Are you sure man? I asked someone and they rekon I will have to send it back to microtech and they have to change it to suit a sr20 and that will cost me $380.

dude y would you have to do that as it is programble with a lap top thats bull shiyt

you can leave the laptop in the car all the time and tune it whenever ??

Asked my tuner. Your lt8 will only suit skylines.

It's the same as saying a stock sr20 ecu with control an rb20. It won't work.

This ECU will only suit skylines with the same motor as teazn_r33.

well my mate just brought one from a fella with a ford and is now using it with a vl turbo with no problems you rmight wanna get you facts straight

can u tell me y it will only suit skylines as i have had 2 professional tuners say other wise

i think you need to see a diffrent tuner if he is saying that

Thank you for your question regarding the Microtech LT8 ECU.

Unfortunately if you are wanting to put an ecu made for an RB engine and put it on an SR you will be required to send the ecu back to Microtech. Our first thoughts were to just try and get Microtech to load a new base map, which is only an $80 cost, but after talking to them for one of our previous clients who had used a microtech on a 4G93 and was changing to EJ20, after talking to microtech we learnt that their ECU's are hardware specifiic units, and when you order an ecu from them it is for that specific engine only. The main reason on why it is not possible is due to different crank angle sensor wiring setups on the various motors.

You can send the unit back to Microtech at a cost where they change parts of the chipset, and alter diodes and resistors so it works on the new engine it will be going in, they also send a new loom with it as well as wires out from the ecu will also differ now.

Many tuners like us get caught out by this if they have not had to do this previously, as I said our first assumption was to just load a new base map until we found out it is a hardware specific ecu.

It is possible to run that ecu on various versions of that similar motor.

For example, the lancer tune ecu we had was able to work on 4G63,4G93,4G92.... etc etc as they all share similar characteristics such as crank angle.

Since you are talking about the RB, I would presume that the ecu will work on RB20,RB25,RB26 and maybe RB30.

That is the problem with hardware altered ecus compared to software altered such as Motec and Autronic, yes the ecu is laptop tunable, but only once the base map has been loaded for that car and the internals changed.

I would give Microtech a call if I was you to confirm this however.

Please dont bother to ring Microtech until after 2pm and before 5pm as they have limited phone answering hours, Id expect the cost of converting to different engine to still cost around $380, my feelings are to just sell the ecu to a similar engined car if possible, as a new ecu is only double the cost of converting it.

Thanks.

Email response from my tuner. Rang Microtech and they confirmed what he said. So maybe you should get your facts straight.

Good Luck with the sale.

    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.
