Howdy all,

Just wondering if anyone has delved into trying to tune a top mount charger with injector cap on a VE V8?

I thought about running a 2nd PCM to multi fire the injector hat, but than was told it "MAY" be possible to run all the injector hat injectors off 1 of the stock injector feeds from factory ecu & run resistors on the rest to make it seem like they were all the same impedance?

Has anyone done anything like it & does it seem plausible or is there another easy solution?

Any idea's & thoughts welcome,

I have heard of people doing that with a ls1 controller but havent seen it in the flesh so to speak of . it should work if the injector drivers in the e38 are up to it if not you could run a piggy back to supply the extra bank of injectors how are you going to operate the throttle id think that would be a night mare

Yeah was thinking while lying in bed to save the extra supply for injector drivers maybe run the single injector to a solid state relay to drive the injector hat & then run resistor on other injector feeds to match resistance of relay, but is 1 single pulse going to be enough for injector hat set?

Then yeah the throttle issue was going to be the next issue as it needs to be cable but still need the original throttle to think it's operating as normal for EVERYTHING else!

I was more thinking of joining all of the 8 injector wires together so anytime any stock injector pulse fires, the injector hat fires.... if the pcm panicks, maybe separate the signals from each other with diodes. you need 8 pulses ot your injector hat per cycle... same as a TBI setup essentially.

Yep I'd try it the same as jayme as for the throttle you could use the pedal and mount the throttle on the fire wall and hook up a rod to the throttle body shaft to operate the butterfly's unless you can mount a matching tps and run a cable I reckon there would be throttle related codes etc hopefully all which could be deleted with efi or hpt
