At the stage of deciding which way to go in regard to ECU.

Do not require any factory controls as there is no fancy bits left.

No AFM's and 1. x single , need straight out good clean HP for drags.

What are the fastest GTR's in the country using , any one have an idea?

I have been told Go MOTEC or next best Halltec, surely some of the jap ECU's will cut the cheese.

Any one have info or results fom the D - jetro experiences? <_<

Wilson's R32 GTR uses Motec

Munro's R33 GTR uses ????

Mario's R33 GTR uses Motec

Theo's R32 GTR uses Power FC (with AFM's)

The SubZero GTST's mostly use Microtech, I haven't seen any Skylines with Haltec's.

:( cheers :D

Munro is running a Motec in his car.

I'm running an Autronic SMC combined with the Autronic CDI.

Next best thing is a Haltec :D I don't think so! I would say the next best thing to a Motec is the Autronic system.

If you have the money, the Motec system is the way to go. You will never look back!

well i have a spanking new d jetro power fc if anyone wants it for 1000

suitable for single throttle body

cheers

fatz , i have been thinking in this direction , but have come up with zero evidence that supports it's ability's or any one who has anything what so ever to support this unit ??

correction.Willall"s use motec and power fc.However fc is only for "knock".Motec does the rest.

motec is the no 1 option

autronics and cdi is next in my opinion

and also ND4SPD in perth with a hks 2.8L stroker and twin hks t04z turbos making just under 800hp at the wheels in his gtr uses the power fc d jetro im 99.9% sure (thats what all the articles say anyway)

www.xspeed.com is where the car is from if u wanna chat to them about it

cheers

You know , it's such a difference in price , a $1300 D Jetro compared to close to $6 K for the motec?

Does it really cost that much extra for a little more Hp or----- does it come down to consistant and reliability 'on the day " monitoring and tweeking to enable the engine to perform under different conditions.

Is this the D Jetro's max ability? I simply do not Know.

The Autronic and the CDI unit , what sort of $$$?To set up properly . <_< post-10298-1126608776.jpg

I'm intruiged, why all the big $$ ECUs in a car that runs WOT for 9 seconds? Honest question, is the tuning really that difficult? Surely the PFC has enough load points for this use? I mean, the quickest drag cars use carbies?

Defin. agree with Dunc's on this one!

We will continue using power fc.....easy to tune. If you need all that datalogging shit with a Motec....then go right ahead....I am an experienced enough driver to tune the chassis/set-up the car with the seat of my pants. Dont need an expensive toy to tell me the car bogged or had too much wheelspin etc. Power FC and a new G-Tech pro RR cost me $1500. whats a Motec full set-up installed?? $8000-$10 000. Spend the money if you need all the help you can get....if not save it and spend it elsewhere.

Boy's, you need to think laterally on this.

The same timing and the same A/F ratio will make the same power, doesn't matter what ECU you are using.

I used an Autronic for 2.5 years on my Sti and I loved it because it plugged straight in. I'm using a PFC Pro on my R32 purely because it's a plug in solution. Both will make the same power numbers on the same car.

What you pay for with Autronic/MOTEC is the race car options that none of us will even go close to using the way the maker intended.

Don't just buy an ECU, invest in a proven and reputable engine tuner - an ECU is just a conduit for a tuner's engine strategy.

So ....... Andrew , what do you think of the D- Jetro?

The Apexi PFC PRO has the the two drag facilitys coupled with AFM's.

This leaves me to say that;

this topic is starting to narrow down to a couple of basic derivitaives( can't spell that ?)

The conclusion is ? <_<

My ECU is MINE's Tuned

I have never used a D-Jetro PFC.

I'll draw a comparison with my Autronic as you could use air flow meters or a MAP sensor.

They only reason a MAP based system is better in my opinion is if the air flow meters are a restriction (either by volume or resolution) or they are prone to failure (like some WRX versions).

Air flow meters are more precise in transient throttle applications particuarly at low manifold vacuum.

I would go with whatever your tuner thinks he can get the best out of.

I'm new to GT-R's and I'm biased towards Autronic. So AUTRONIC FOR POWER!! Go the SM4 http://www.autronic.com if you're not using AFM's.

    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
    • It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
