hey guys

hoping someone might have had experience in this prob. I got a mailorder chip for my ecu

which is sposed to have different maps, speed limiter cut, rev limiter change and other stuff.

So i just put it in and my cars running like a bag of shit! The EGT light is flashing on the dash

and it feels like driving with an intercooler pipe off. Idles fine but breaks down heavily underload.

What have i done??!!

Any mail order chip is a gamble. Some seem to work well but unless you put it on a dyno or otherwise check afrs, timing etc you can't be sure that you're not damaging your engine. A chip other than Nistune is OK if it is tuned in your car for the engine and mods that you have but Nistune has the advantage that there are many tuners able to work with it.

its like that because youve probably gotten the wrong MEC chip type

when you get the wrong MEC chip type the car runs like ass basically

whilst there are s1 and s2 ecu's, there is different MEC chip types for some wierd reason and if you get the wrong one, it runs like ass

i had a mail order remap long long long time ago s2 GTST with S2 remapped ecu, it ran like ass, turns out i got the wrong MEC chip type

so essentially, you can't use it

remaps are junk, you should never buy a remap

if you insist on remap, remap your current known working ecu with nistune

I suggest you contact Toshi on this forum about resolving the matter.

He can put the right chip in it and remap it to suit your setup. Despite people saying remaps are crap there are no negative results from Toshi and plenty of people use him.

    • Hi guys, I’m new to the GTR scene. Picked up an R33 GTR earlier this year that needs a lot of love. I’ve been going through the hot side, changing all the gaskets and while it was all off I managed to score a set of -9s. It still had the stock ceramics so I was pretty happy to get the 2860s.  I live in a small country in the pacific with 0 performance car scene. No dyno’s no performance parts, let alone stock parts for a skyline. I order everything from Australia and do it myself. This means I’ll be running the stock ECU. Maybe down the track I’ll get an aftermarket set up and do a remote tune.  Will the car run -9s on stock tune safely?  I have a very heavy foot so I really hope so 😂   thanks guys   
    • perfect, no rush to address the leaking bush then, it's not doing much/anything
    • I'm not sure if it will bolt up, but.... I'm reasonably sure that the ID of the runners is somewhat smaller on the NAs. So it probably wouldn't be a good match at the flange where the top and bottom meet. So that would be a reason to not do it. And the skinny runners would be the bit you're keeping, which would be a reason to no do it. You'd want the big runners if you were doing any work to swap stuff. Why not just use what you've got, like nearly everyone else who has +T'd an NA? You don't need or want the TCS throttle or other stuff that is specifically DET inlet/crossover.
    • lol already been put in temporarily 3 years ago
    • Makes sense. For actuators, if the pressure itself isn't adjustable, that would mean I'd need to think about 2 different actuators with 2 different pressures on paper in order for them to work at the same time if the turbos behave differently. So measure the difference in psi needed to move both, and then get an actuator to match that difference. Assuming I cant get rid of it by adjusting the arms.  You're exactly right, never happens in gear 1 or 2. I can occasionally get it in gear 3 if going uphill but its very small. Only ever in 4 and 5. Seems kind of backwards that one of the points of VCAM is faster spool but if it introduces shuffle then it actually slows spool down.
