Impul_GT-R

A lot of people were heralding NCOP as the end of the modification world. I truly hope to see this project of yours go through with engineering approval to get full rego to show that if the quality of work and engineering practice is good, you can still have your toys. Your attention to detail and quality of work has my respect.

Either way it sounds like you're on top of it, from an engineering perspective it would have been nice to identify the issue before blanket fixing it with another ECU. Injection timing adjustment is available on v10.127 now by the way but it's only injector phasing (so the adjustment is in 120 degree steps on a 6 cyl), not injection end angle adjustment as is the case the with the 1280.

+1 agree it's not because you were running wasted spark, especially on Nissan coils which only need 1.8ms of dwell time. If you do that maths at 1.8ms dwell a wasted spark setup could support up to around 12,000rpm. Interested to hear if it was a FW issue, The e1280s will give you full sequential fuel delivery, end of injection timing and whatever fuel/ign calcs your tuner might want to dream up if he's competent with the advanced view interface though.

Out of interest, which version firmware were you running in the select ECU with the misfire problem? With the Nissan trigger there was a problem above ~6000rpm between versions 10.105 and 10.126 which has been remedied in 10.0127. If your version was outside of that range then it must have been something else.

Hi Rob, some answers to your questions: Do they have closed loop narrowband/wideband control? - Yes, RS232 input for wideband from Innovate, Techedge, FJO, AEM & M&W so it won't inappropriately go into closed loop during sensor warmup or a sensor error condition as the sensor state is defined in the serial datastream. The ECU will fallback to a sensor connected to the analogue input in the case of a wideband error condition given you have a second sensor configured (eg OEM narrowband sensor in vehcile full time to run closed loop and come dyno time simply connect RS232 cable to have wideband logging and adaptive tuning available in the ECU, no software change needed just plug it in to tune, unplug when finished and it'll go back to using the analogue narrowband one automatically). Individual cylinder trims? - Not yet, but this is planned to be available in the next major firmware update. The firmware release cycle is fairly swift from my experience. Variable ignition attack/decel rates? - No Delta idle ignition control - Yes Im also guessing they only have 4 saturated injector outputs - 4 outputs yes, but they're peak and hold drivers adjustable from 0.9A - 1.9A holding current, peak current 4x holding current for ~1ms from memory. Variable cam control? - Yes, you can control either inlet + exhaust independently with programmable PID gains for different engine rpms to account for the control characteristics changing with oil pressure, or 2 x cams from the same target map. VVT maps are either 2 or 3D at discretion of the tuner. The select range only has 3 PWM capable outputs so doing a quad cam VVT engine is outside the scope of this ECU, but not its big brother the e1280s. What's the trigger filtering like when using inductive style triggers? - There is nothing definable in software like available on the Motec M series ECU's from firmware 3.x onwards. On the inductive triggered engines I've done, provided you don't have ground loops in your wiring or anything silly with RFI I've not had problems. I'm scepticle they will completely solve your ignition issues with just a change of trigger disk on those few cars that do have issues... - It's good to be sceptical, too many people believe what they are told without checking the facts for themselves. I think you may have misread what Anthony said, in his experience he hasn't had to change trigger discs to fix triggering problems with the Nissan CAS using the Select ECU as has been the case with others. They're worth having a play with if you get the time or opportunity. Download the software and have a look, it's clear from your questions you obviously know your way around engine managment systems

I haven't had those trigger issues on the select like as seen with others. I have logs of Select ECU's running Nissan engines to 9000rpm without the any of the RPM artifacts you've described - I have no doubt you'd be familiar with sawtooth looking RPM traces pulled from Motec's etc. The engine position being derived from the 2 degree windows has a lot to do with Adaptronic's immunity to this.

Nice write up Anthony, I'm not suprised you've found the Select range fantastic to tune for clients and yourself as have I. In particular with the Nissans, Adaptronic utilizes the 2 degree tooth windows from the CAS to provide more accurate ignition delivery and faster starting compared to many others. In my opinion the features, performance and support you recieve with this product is without peer, especially for the price. It takes a tuner with an eye for detail to fully appreciate the depth of programmability available if you choose to leverage it, especially with things like idle control as is evidenced by the experiences you have shared above. I have tuned several Skylines in the 600hp to 800hp bracket with the plugin range and they work a treat. Up until a few years ago when I took the Adaptronic brand on the only ECU I would sell and support was Motec. Today I would install and tune ten Adaptronics for every Motec I do now among all the other brands we tune if brought to us. I would recommend anybody in the market for an aftermarket ECU to find a workshop or tuner familar with the product so you can judge for yourself.

Hi, fitting a R34 getrag 6 speed to my R32 GTR, I have the box but need: * Front tailshaft * Rear tailshaft, or at minimum the front half of a rear tailshaft * Gearbox cross member from a R34 GTR * R34 GTR gearknob If you have any of the above please PM me!

lol that's faster than you went at the Maryborough sprints... (or any of us for that matter!) Weren't you heading up that way only a couple of months ago when you dropped into wheels on wide bay for a look this year? P.S. what's with you not getting a drive yet Russ??!

FYI... I think the most impressive effort was the fact that Brad's full weight (1560kg without driver) legally registered R32 (car 131) running street legal tyres ran a 35.33sec making it the fastest ever street registered GTR to lap the Gatton track. The unregistered one (car 135) ran a 34.068sec on factory brakes which were really letting it down. Both cars running pump United Boost98 fuel which only cost $1.17/Lt that weekend. Both times done on cold tyres and brakes, maybe next time he'll double enter a car so the first driver can get everything nice and up to temp for when he takes it around which history has shown us is good for 1.0 - 1.5 sec off your time at this track.

Looking for a spare hand controller to suit an Apexi Power FC with the following detail: The sticker on the back of the handset must have FCC2 written on it to suit the firmware in my unit (it's a powerfc pro). The older controllers have this firmware which is denoted by the FCC2 on the sticker. As an example my hand controller which works has "FCC2NT010" written on it. The detail that's important here is the "FCC2" bit. I have tried later handsets and they don't work (display locks up on startup screen). So if you have a controller lying around gathering dust or simply not being used get in touch with me and turn it into some cash! Your car will continue to run fine without it and you won't have to worry about your mates mucking around with your tune! Thanks.

Got one for you, PM sent.

Got one for you, PM sent.

Jas, Looked again at the datalogs your absolute max boost was 18.8psi - those runs were done at 18psi, not 20psi! Here's a quick vid of your last run the 9.882 @ 146mph + the burnout on the 9.364 run. SAU_Benaraby.mpg

I'm assuming that this is at Queensland Raceway? I should have my GTR back together by then after popping a turbo in the hot laps at Cruisetime

Sorry I couldn't post pics guys as it turns out we didn't take nearly as many as I thought; but here's a quick vid that was taken by one of the guys from our campsite. It shows fullysic running a WRX.... don't know if he beat it, as it looks like a close run... Maybe fullysic can tell us if he did paste the WRX...? :kick: Enjoy. MPG video here (zipped)

Hey guys it's a wicked event, I went to Powercruise last year too so as soon as we found out a replacement event had been organised for QR again this year we were there! I went down with our group from Hervey Bay (400km drive) for the whole weekend arriving Friday 7am in the morning so we could get a good campsite. They weren't going to but they let us run around the track that afternoon for two hours!! I took the GTR around for the hot laps after having only just finished tuning it for 1bar on standard turbo's at 9pm thursday night (I never leave anything till the last minute!! hehe) and well wasn't doing too bad save for the f**ked falken azenis tyres I was running on with too much pressure as instructed at the drivers briefing - 40psi hmph! I'll stick to 34/32psi next time. Anyway coming up the front straight in lap 4 one turbo cried ENOUGH! ... oh well at least it made 329.1rwhp earlier that day... Which leads me to my next question... anyone got a standard R32GTR turbo they wanna sell?! I disconnected the wastegate actuator on the good turbo so I wouldn't stuff it as well on the way home. Drove it home last night with no boost :Oops: Damn what a slug! I even lost a race to our support vehicle - a turbo diesel patrol! I've got a few pics might post them later today... Anyone else on the forums go?

Complete set of four R32 GTR wheels fitted with Falken Azenis 225/50R16 tyres. The tyres DO NOT have legal tread depth left so if requested can be removed to save $$$ on shipping. Purchasing with or without tyres will have no effect on the price as they aren't road legal therefore in my opinion worth nothing (other than burnout value for those of you that way inclined). The wheels themselves have very little in the way of gutter damage which is the way I purchased them from the previous owner about 2½ years ago. They have only once been used on my vehicle for a session at Qld Raceway (all 15 laps of it) so I figure there's not much point holding on to them as I no longer require them due to a brake upgrade (read: they won't fit anymore!). I paid $1750 a few years ago including freight I am asking $1200 with the purchaser to pay and arrange pickup. I'm in Hervey Bay, Qld which is 300km north of Brisbane on the coast. I can take some clearer photos and email or post them if anyone is interested. Either PM or email me [email protected]

Haha yeah I couldn't agree more some of the decisions I've seen over the years for "best" whatever category car at shows has left me (and others) wondering. You generally find that the people who vote an off the showroom floor brand new car the winner are generally the people who read and believe what the writers of MOTOR magazine and the likes have to say! Naturally we'll probably never see Nissan as a designated car category because as is Japan's way they copied what others had done except they did (and still do) it better. Although we may yet see plenty of imports making their way up the hill provided the established players with their historics don't get annoyed with the fact that we don't have to measure our straight line speed in eighth mile (as opposed to quarter mile) to prevent our E.T's being recorded in minutes and seconds as opposed to seconds and fractions thereof (just kidding guys!)

Damn you must have been waiting to jump on me that reply was quick!! I'll get that entry done this week look forward to seeing you there. My parents in law will also be making it there with their blue 300zx (g'reddy TD05x2 + 2x ext. wastegates + trust coolers etc...) and their black V12 twin turbo XJS Jaguar. I'll enter both my cars that way I should get at least one accepted! I've got a friend at Coolum with a white R32 GTS-T who would probably with a bit of arm twisting attend the Noosa Beach Classic next year also. I recon if we do what the Porsche club did (and that is practically take over the show) they won't have any choice BUT to acknowledge us!

Was a good event, I'll probably enter mine next year. On my way home I went for a spirited drive up "the hill", I think I'd better get that entry form filled in and mailed away for the hillclimb for this year - they've resurfaced most of the road up there Matt I think you should enter the 33 too! I had no ground clearance issues. Hopefully I'll get the GT-R in under the category of "future classics", the HRCC are a bit funny with modern cars in that event.

Just a thought, you have got your ignition trigger set to negative or falling edge haven't you? Given that you (or your installer) set the dwell time correct I'd imagine you'd have the this correct also but what you're experiencing is very unusual so it pays to look at everything. The coils would take a few months of torture before they fried so it is possible that they survived for 12 months before giving up the ghost. Good luck! Bradley Smith

Took the words right out of my mouth Steve-SST! The charge time or dwell time as it also known is very important to the longevity of your coils and ignition modules. Correct dwell will also bless you with more spark energy. Any more than 1.8ms with the Nissan coil-on-plug coils and they will saturate. Once they saturate (ie the point after 1.8ms of charge time they are still being charged) the current drawn by the coil rises sharply and accordingly that rise in current is dissapated as heat. I see people make this mistake with Autronic ECUs all the time as unless you option them with a dwell board ($600 later...) the ignition output is constant duty... Then they wonder why their engine idles like a hairy goat and you can cook on the ignitor/s and coil/s. In short, make sure your charge time is set to 1.8ms for any of the nissan engines running factory coil on plug coils and you'll have no more problems. If you are interested in more info I might capture some oscilloscope traces next time I'm setting an ignition up. When you can "see" what I'm describing it's a lot easier to grasp. Regards, Bradley Smith

Yes that's correct only one, depending on what the insurance decide to do I may require two (the repairers damaged the other one... don't get me started on them!!). I believe they are a two piece wheel, all I *really* require is a fresh outer. If you are in a position to supply could you please provide me with a quote in Australian dollars which I can submit to them for the cost of one or two wheels landed here in Qld.

I require the RS527 which are a 9.0JJ~18{25 which are listed at 112,000 Yen before tax. While I'm at it I'd also like to order the wrench for the center nuts which are 2100 Yen. Have a look at that site in English it's so much easier to follow! Brad
