Kenian Posted August 12, 2020 Report Share Posted August 12, 2020 Hey Guys, I have recently got my B18CR turbo EG project somewhat finished and ready to start - below is a rundown of the basic setup to give you a picture. B18CR unopened (11.1-1 CR), t3/t4 turbo, Skunk 2 70mm TB, 1000cc Xpurt injectors, 500hp Fuel pump, Link IAT pre TB in intercooler pipe, Link 4 bar map sensor, link g4+ PNP (HC96). AEM X series wideband over CAN. NGK BKR7E copper plugs - 0.60mm gapped. I have got the stock base tune map and adjusted the MS fuel number from 22 standard to 12 or so. I found the car runs ok here and once warm and the warmup enrichment compensation is not active it idles around Lambda 0.97 - 1.00. I have run through all the normal first start procedure - TPS Cal, MAP Cal and have set the base timing with the light. The car starts after a bit of cranking but definately isnt smooth or easy and once running i need to keep the throttle slightly open as it just dies as soon as it the revs start to get anywhere near 1000 rpm and trying to restart the car once it is a bit warm is impossible and will not start at all. Please note the car doesnt and has never run a idle air control solenoid (not sure if this is making things worse or not) as the previous owner has blanked it off and installed a skunk2 70mm throttle body and never had any issues idling on the standard ecu or on the link when it was still non turbo. I have attached the log of first start to get it running and obviously it dies. Please note i am messing with the MS fuel number while the cars running (between 11 and 13) to see what it likes and ive also messed with the ignition numbers in the very low load/idle areas to see if that can help it stablize the idle. I have also attached the log of cranking it the second time to try and get it going again with no joy at all. I also note the trig count error number is climbing which is obviously a problem also so i have attached a trigger scope pics and logs. Any help is much appreciated guys - just want to get it running and idling ok so i can get it out the garage - up the drive and on the trailer.
