    Well, Ive got a new problem now which really has me stumped. While attempting to install a GM coil pack, I shorted the coilpack power(between ICM and coil) to ground and popped a fuse. Since then it wont stop misfiring/running like crap and knocking at idle. Ive got spark at all plugs, plugs are new and gapped at .022. Plug wires are brand new. Compression and timing is good. Pulling #2 and #6 plug wires have no effect on idle condition, but the other wires being pulled makes idle worse. Disconnecting #2 and #6 injectors makes idle better. Strange thing is, im getting spark from all 6 plugs. S

    Forgot to ask, last night I did a couple pulls through first and second and shredded a brand new belt? You guys ever heard of this? The belt had a very small tear from the dog getting a hold of it but I don't think that caused this? I mixed and matched mk3 and mk4 accessories, they don't have different numbers of pulley grooves do they? The uphill battle continues... *Edit: got this sorted. Had the pulley on backwards.

    i get your point then. Functional logic? A little over my head. I would love to be able to tune and understand these ecus like you do. I can't even manage to connect to one though. Would probably help me out a lot if I had that capability.

    Wow, great info. Seriously, thanks for the in depth info. That is a rarity on any forum. I hardly feel worthy of such wisdom. It's going to take me some time to digest all of it. i think I understand that your saying all the proper ingredients need to be intact for the particular tune. I've already got all that covered. As for the bank specific readings, I'm still a little confused. The standard 12v vr6 only ever has 1 bank even from the factory. Both exhaust manifolds join in the downpipe and have a single pipe back with one primary and one secondary oxygen sensor. Feel free to correct m

    Is it possible cam timing is slightly off? Compression #s were from 150-170. As for the bank specific readings, all of us on c2's tune generally use the ATP style one piece cast manifold, (with O2 sensor in the mid pipe) most with success. So that's probably not the issue. AFR's are all over the place, except when idling and vac is low so I'm leaning toward a fuel system/sensor/vac leak.

    I've already checked the oxygen sensor and compared it to the wideband sensor and they match identically. Got the car running in and out on the road for about half an hour didn't go too crazy but noticed wideband was all over the place. It stayed stoich when cruising steadily. But anytime in and out of boost it jumped all over the place. Another problem I've noticed is low vacuum and I can't locate the problem. Have already done a compression test and boost leak test .

    For those of you that would rather have the information here: Rebuilt the motor (new rings, bearings& timing chain kit and ARP head studs). Also built a full 3" exhaust, switched to a SRI and added a front mount intercooler. Fuel injection is still C2 Stage 2 with Bosch 440s & 4" MAF but added an inline Walbro 255. Also replaced the fuel filter and now have functioning wideband, boost and fuel pres. gauges. At first I was running extremely lean (17.2:1AFR with ecu adding 25% fuel) until I changed my Intake/MAF configuration. Now I'm running stoich but the ecu is cutting abou

    Well here's an update everyone. (I'm the OP just switched usernames) After a year of meticulous rebuilding I've finally got her fired up and running decent. If you would like to see my current thread and read what's going on here's the link: http://forums.vwvortex.com/showthread.php?7771897-VRT-Running-Very-Lean&p=94896073&posted=1#post94896073

    Hey guys, Just finished my MK4 12V VRT build with C2 440cc flashed ecu. Car starts momentarily then dies. If I auto-scan I get this code: P1388 35-10 "Control Module Malfunction" - DBW Throttle Monitoring Anyone familiar with this code? There isn't much info on the forums and I honestly don't trust a dealership on this one. Thanks for any advice.
