o.O, that would be my car.

umm lt12s is having issues once warm reguarding the rpms around idle. Its glitching out and sending all kinda of crazy rpms signals to my ign box and coil packs. anywhere from 250rpms to 16000 rpms. Its on its way back to the AU for repairs.

The middle part is where the car didn't want to start is where it was just starting to glitch out on me.

lt12s swapped to rb20 ecu? That wont work....

Yeah I know intercooler is massive thick. I just didn't feel like ever having to re do the piping again if I ever went bigger. Being its all hand made and tigged up.

thanks Bill. already having bad.

The way I see any complete standalone out there has its quirks, its more or less luck of the draw if you have issues or if you don't. They all have their positives and negatives.

Microtech is far from cheap and right in the middle of the pack with standalone prices. Any standalone is upwards of 1500 for the RB series motor when everything is taken into account... Its a fairly efficent and easy standalone to use compared to say the AEM unit which has a good deal more intricate maps.

Now if only it had functioned right for me from the start... I'll see in a few weeks when it returns.
