Default VW G60 lysholm charger running WAY rich

ok this is a friends car

1992 GTi w/ a G60 swap and an upgraded blower and this ******* runs rich as hell (no WB on it yet but its bad)
no matter what we try it constantly runs rich to the point that gas could pour out the exhast at any minute and barely runs

stock ECu w/ stock inj runs fine (didnt try to drive for obvious reasons)
stock ecu w/ stock injectors w/ FMU turned all the way down, runs rich (normal FMU condition, just figured we'd try it)
chipped ECU w/ 40# inj runs rich.
chipped ECU w/ 40# inj base fuel pressure turned way down runs rich


w/ the car running fine on the stock setup i'm sure the wiring is just fine. cant figure out why it wants to dump so much fuel with the chipped ECU. the program for his car is what the SC manufacturer recommends.

any ideas??

I was actually working on a 91 G60 tonight, they are pretty fun cars besides the random electrical fires and bitch of a supercharger. If he still has that ISV valve ( looks like a giant fuel injector on top of the valve cover) you can re-route it back into the intake charge pipe and plug the hole in the return (if its still there). And make sure the ecu is grounded GOOD, they are real picky. I cant imagine any "chip" a manufacturer would send with a supercharger will have an entirely accurate tune, thats more than likely the biggest problem.



Edit: Is this one of the "stage" kits available? if so which one and did it come with the camshaft? I am looking at one of these upgrade kits for that motor they seem to run about $300 for a 17psi pulley, cam, and chip.

i think it is just the first stage: blower, ECU, inj, intercooler. he should be making around 200hp.

i'm sure the manufacturer knows what will make the car run decent but not perfect, but this is bad.

lysholm supercharged cars are the most annoying thing i have ever heard...im getting flashbacks to WaterWagons and the BaunBrenner cars..

anyway chips for VW;s dont work... you want your VW to run right? swap to standalone [includes stock cars :P]...

Lysholm chargers are def annoying, they sound like an old fire truck siren. I don't miss my G60 one bit, well except for handling and braking.

i was thinking to just run the stock G60 ecu and injectors and put a wideband on it and see what it looks like. if it was lean then try throwing a 3bar FPR on it.


i suggested MSnS but he doesnt want to throw money at the car just to get it to run right when people have made this setup work

I had a problem with mine running rich at one point, turns out it was a bad oxygen sensor. If your sure it's not the chip than I would put the stock injectors in with the chip and see what happens.

it ran best w/ the stock ecu/inj and FMU but still isnt right at all, he may just haev to deal with it untill he gets some a better EMS.


i've seen MK2 1.8t swaps go easier than this
