Yes

Just got my gt35 fitted to an older protomotive conversion. Had to rework some of the exhaust to clear the tire. Wow, great improvement over the older turbo. Full .5 bar almost immediately from 3k up in the upper gears. Thing flies now.

You had to rework the exhaust to clear the tire? I’d like to see what you had to do there.

Lyle-did you use the position for +6% or +6 with ign retard? About to adjust mine. I don't actually have an afr meter but my plugs have always looked slightly lean.

Actually, I dialed in the position with 6.3% enrichment and 2.79 degrees of retard. The retard affects the overall HP output, but adds some safety again detonation. When I dyno, then confirm everything else (fuel system pressure, and fully plotted AFRs and boost), will probably reduce the retard at the switch to zero, but add a bit back in the EPROM. It runs really solid now, though.

I'll send pics later. Car has stock heat exchangers and the original protomotive kit barely cleared my rears. The gt35 was just enough wider that I had new stainless fabbed to move it inboard a schooch. Will have car on a lift tomorrow or monday and post pics.

At 10:1 you were probably blowing a lot of black smoke out the exhaust. You are leaving a lot of power on the table at that AFR also

All seems a little baling wire and duct tape.

3.2 is an EFI car. There was a piggy-back in-circuit emulator for the Motronic developed a few years ago (guy posted on the 911 forum) which would let you tune maps interactively, log and all that modern stuff - then burn an EEPROM when done.

But given that you've already got most of the sensors, just adapt the factory harness to any ECU developed in the last 20 years.

You wouldn't even need to add MAP/TPS, cam sync or switch to modern injectors all at the same time, do that incrementally later.

Had to lengthen inlet to turbo and change it from 3 bolt to t3, and that required redoing the exhaust plumbing. Had I known, I would have gone with a v band compressor side.

Oh wow that's interesting location of turbo. Is that protomotive kit location?

Yes...but a very old protomotive kit, early 2000's.

Was that the unit from RaceBoy in Lithuania?
I'm still interested in his unit and wanted some feedback from those who have installed one.

RaceBoy's ecus are not piggybacks; they're VEMS full standlone with an adapter harness. I'd stay away from piggybacks for countless reasons. As far as VEMS goes... No issues with mine so far other than issues I've created myself (ie. wanting more boost and blowing plenums apart lol)

GTK, thanks. Not at that point yet, but inching forward.

No, Sal (scarceller) in this thread, starting post #132 http://forums.pelicanparts.com/porsche-911-technical-forum/452932-tuning-programmable-engine-management-systems-4.html

993Speedster is right; a piggyback that lets you tune/live-map the Motronic does have an application - but a very specific/limited appeal. And tons of compromises for forced-induction applications.

Stand-alone management would be better in almost every way.

Raceboy seems well on top of things & knowledgeable; I'd made a note of his kit, but ended up with something else.
