1 question i have that im gona send an email away is if i get the v88 and i get it tuned for the neo motor and i put a different motor in like a 26 can i load a 26 map into it later and tune that or i have to get another ecu.

can anyone confirm that the v44 plugin will run low impedence injectors without using a resistor pack?

I have heard they from different people that they will but have also read you need a resistor pack.

Anyone done this yet?

Vipec V44 plug-in manual:

GTR models are fitted with LOW impedance injectors run via factory fitted ballast resistors. This ECU has been designed to be used with HIGH impedance (greater than 6 Ohms) injectors. Ballast resistors must be wired if low impedance injectors are to be used. This means that the ECU is plug-in compatible with factory fitted injector/ballast combinations on all models.

with the amp or with the figures in the knock map?

with the amp. i'm keen to know how people are setting up the knock response threshold since it's hard to know what knock sounds like for a given engine unless you can produce it. ie no point having the knock function set at a threshold such that the thing is rattling away but the ecu does nothing because the knock severity at which it acts only occurs when the conrod exits the block.

unless of course it's a noise filter like the Turbo XS Knocklight.

would also be nice if they could find a way to use the standard knock sensors on the GTR.

it uses the standard sensors, the plugin and the V44 need an amp/signal filter so that the input is 0-5v without much random signal noise where as the V88 has that built into the unit.

Ear muffs/det cans. :geek:

i know how you listen for knock, what i'm asking is how you set the knock correction point if you don't know what knock freqs are for a given engine.

if it was standard practice to get the engine to 'just' start knocking and set that as the threshold for the ecu to trigger knock control there would be no question, i just don't intend getting my car tuned that way.

Turbo XS claim that once the procedure of calibrating the Knocklight to the freq range of normal engine noise for a given engine - ie without knock - is complete, it recognises freqs outside that as knock. they are confident that the unit will pick it up correctly because knock freqs are fairly unique. in other words it detects freqs outside those parameters as knock, although the suggestion is that knock freq range is extremely narrow. i'm not advocating their approach but i can see it's plausible as they use the parameters of an particular engine's unique freqs.

another example; the stock GTR ecu has knock control but if you use it on an RB26/30, which will have a different knock freq to a stock RB26, there is no guarantee it will be effective as what it hears when a 26/30 knocks itself to death might be different to what it has been calibrated to recognise as knock.

hope that makes sense.

just not sure how it's done with the Vipec.

With the vipec can you select high or low impedance injectors?

Also just wondering considering the current group buy on the Haltech E11V2 @ $1545

Why would you choose the Vi-pec over the Haltech?

Those who have the v44 whats your idle like? Now I have the injectors and hks turbo on, the idle seems to hunt a lot, where before it was almost flat as a tack? Is it worth doing some data logging?

your engine didnt eat turbo bits did it?...probably only a simple air leak though...are the injectors sealed where they seat on the head flange?

My engine may of eaten some small turbo bits, compression test came back regular no cylinder vastly different to the other., some small metal flakes were found around the intake and around the IM. Intercooler piping etc was all cleaned out. What do you mean by are the injectors sealed?

Wasn't doing this for the few mins I had the car idling after the turbo blew.That was with the old injectors

thx

they have small rubber insulators that seal the injectors to the head...its quite common to not seat them correctly allowing a small amount of air to enter the system which is making the idle hunt.

Frankly I wouldn't know, I have the software to monitor the ecu, but I havent had the chance to use it.

edit: I'll have a look tomorrow to see what I can around the injectors, thx for the tip.

Will see if I can do some datalogging of the ecu on friday as well.

thx

    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
    • @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html
    • These going to fit over the big brakes? I'd be reeeeeeeeaaaall hesitant to believe so.
    • The leather work properly stunned me. Again, I am thankful that the leather was in such good condition. I'm not sure what the indent is at the top of the passenger seat. Like somebody was sitting in it with a golf ball between their shoulders. The wheels are more grey than silver now and missing a lot of gloss.  Here's one with nice silver wheels.
