boab3 164 Posted June 22, 2017 Author Report Share Posted June 22, 2017 Inlet manifold off now and it's really strong smelling of fuel ill pull plugs out make sure they are all the same colour incase it is down to 1 injector leaking Link to post Share on other sites
boab3 164 Posted June 22, 2017 Author Report Share Posted June 22, 2017 Well all plugs sooted so definitely all cylinders running rich.refitting original standard injectors. See if that helps Link to post Share on other sites
boab3 164 Posted June 23, 2017 Author Report Share Posted June 23, 2017 Standard injectors wont run on United motorsports chip i presume its due to the map on the chip being done for larger injectors.is there anywhere who can flash my chip with a standard map to get me running safe so i can get it custom mapped.i now dont want to remove standard injectors id prefer to keep them with the 4 bar regulator Link to post Share on other sites
Gazbvr6 16 Posted June 23, 2017 Report Share Posted June 23, 2017 I'm assuming u haven't got your original chip? Link to post Share on other sites

boab3 164 Posted June 23, 2017 Author Report Share Posted June 23, 2017 I'm assuming u haven't got your original chip?Hi mate are you running a z engineering supercharger? Are you running z engineering software or have you got a custom map done? Link to post Share on other sites
Gazbvr6 16 Posted June 23, 2017 Report Share Posted June 23, 2017 Yes i have mateI had mine remapped at stealth boab3, VR6 Supercharged and VR6Pete 3 Link to post Share on other sites
boab3 164 Posted June 23, 2017 Author Report Share Posted June 23, 2017 Found my original chip will try it later on Link to post Share on other sites
VR6Pete 1,455 Posted June 23, 2017 Report Share Posted June 23, 2017 I would highly recommend going to Vince at Stealth, but appreciate its some distance from you! There is a local B&B I have stayed in where work has gone over 2 days or to break it up a bit I run 320CC injectors, 4bar pump and uprated fuel pump @ 9 PSI but of course all needs mapping in. Thing is with the chip you have, looks to be "protected" so no other tuner can meddle with the map - throw it away and get it mapped for the hardware you have. boab3 and Gazbvr6 2 Link to post Share on other sites
boab3 164 Posted June 23, 2017 Author Report Share Posted June 23, 2017 I have a company i have found that deal with vws and mapping etc ive emailed them with details. They are 30mins from me Link to post Share on other sites

boab3 164 Posted June 23, 2017 Author Report Share Posted June 23, 2017 Well i went back to basics plugs out gaps good dizzy cap off and seems to have blown a hole on one cylinder glad ive got spares.this could equate to the slight rough running at idle so change this out tonight.checked for voltage at maf all good just to rebuild up again and ill pull maf plug off just to i double check the maf is working.

boab3 164 Posted June 24, 2017 Author Report Share Posted June 24, 2017 Ok new cap fitted 310cc injectors and chip back in running much better this .code o2 sensor limit surpassed i had forgot i had this fault before fitting charger i presumed i cured it by buying a new bosch lamda.obviously hadnt and this is why im running rich even more so with bigger injectors etc.lambda plug on car loom has 4 wires the yellow that connects to pin 42 in ecu i think is the ground for sensor has corrosion on terminal.im thinking as the lambda detects a lean mixture the voltage would be low and if rich it would be high.as ive got a corroded terminal id have no voltage to sensor so in theory itd be thinking its weak and firing more fuel in. Job for 2moro replace corroded terminal and try it out.its running fine just now but still coming up with lambda control limit surpassed VR6Pete and Gazbvr6 2 Link to post Share on other sites
boab3 164 Posted June 25, 2017 Author Report Share Posted June 25, 2017 Well wont be getting continuity through that terminal its the earth for sensor side not for heater side.hopefully found the problem Gazbvr6 and VR6Pete 1 1 Link to post Share on other sites

boab3 164 Posted June 25, 2017 Author Report Share Posted June 25, 2017 My theory is no contact no voltage.no voltage makes ecu think its running weak or sensor fail if it does fail or think its weak it automatically puts an extra 25% fuel in as a fail safe Gazbvr6 1 Link to post Share on other sites
boab3 164 Posted June 25, 2017 Author Report Share Posted June 25, 2017 Yesterday with ignition on the vcds was showing the o2 active as 1.0 tonight after repairing cable its 1.85 so made a difference before even starting it up.will tell 2moro how it is.im not really sure what the vcds o2 active actually is monitoring Gazbvr6 1 Link to post Share on other sites
boab3 164 Posted June 26, 2017 Author Report Share Posted June 26, 2017 Well vcds now alternating o2 active limits when running seems much smoother did scope of o2 and has a fluctuating graph now so all working.just 1st start this morning didnt want to increase idle on cold start but im going to get it mapped anyway as its idling fine revving throughput the range with no dips and rests back at idle and stable.so time to hit the rollers see how much this mapped chip i have runs on the rolling road Gazbvr6 1 Link to post Share on other sites
Gazbvr6 16 Posted June 26, 2017 Report Share Posted June 26, 2017 Well done mate. Seems you have cracked it boab3 1 Link to post Share on other sites
boab3 164 Posted June 26, 2017 Author Report Share Posted June 26, 2017 Well done mate. Seems you have cracked it Cheers mate i suppose old wiring prone to corrosion but i totally forgot i had issues before fitting charger.at least now i can see o2 moving on vcds.disconnect maf it cuts out same with throttle switch it cuts out so ecu must be using them.so far so good Link to post Share on other sites

boab3 164 Posted June 26, 2017 Author Report Share Posted June 26, 2017 Good stuff!!I'm interested to see what power it makesSo am i im crapping it as i never run my vr hard.no big mods just a 2.9 inlet and throttle body and the charger.im hoping for nearly 240 Link to post Share on other sites

LolYou will need to run it hard after, as they dont make 6psi till about 6000-6500rpm!! VR6Pete and boab3 2 Link to post Share on other sites
