Default It's ALIVE it's ALIVE it's ALIVE.. got it :)

Tried tonight. that b18b in the 92 Hb Plus turbo is DAMN fast. Injector problem were made cause by a resistor pin that got broken when I taped the whole thing together. So, I am tuning using ECM SMG+, when I WOT in 3rd, the af meter is showing three green and one brown all the way, from 2000rpm to 7000rpm. But there is a problem, when I press the pedal to 2000rpm while in neutral and keeping my feet still, the tach goes up and down, like 2500rpm, back to 2000rpm, 2500, 2000, 2500 etc.... Neones know what's the problem?
Also, it's very rought at idle... tach is boucing.. but at 3500 and up, everything is fine.

Thanks

did you put an aftermarket fuel pump in there without controlling the idle fuel pressure?

You can tune it out a little, but that 'holding the rpm still' problem is present with the SMC, AFC hack, and greddy blue box (so i've heard on this one). The AFC hack did it real bad for me at first but i leaned it more and it got better. It's just somthing that happens when you go ghetto. it's no biggie, it only happens in neutral. all is well!
