Fixed! 1.6 w. DIYAutotune MS1 extra start issues
I really need some assistance with this.. I bought the MS1 prebuilt by DYI and did the DYI mods for CAS and ignition. I actually had it started on the first try, had it running up to standard temp, but it really ran like a POS. Realized I had only half RPM on Megatune compared to car tach, so I switched primary and sec tach inputs. Now it reads about 200 RPM at cranking, but it wont start! What I do is:
Set Lambda to Standard NB and temp to F to accept the DIY No MAF .msq file.
Open the .msq and burn it to MS.
Set lambda back to LS1 WB and temps to C to match my environment.
Req fuel is set to 13.5.
Check the inverted spark is set to NO.
Crank, and it occasionally catches for a revolution or two, but never starts. Sometimes it pops in the intake, and if I run flood clear, it may pop in the exhaust. Pulled a plug, and it looks dry, a bit black but I guess thats from my initial startup.
I´ve tried req_fuel values from 9 to 18 without any success. I have stock 1.6 injectors in. I also have the greddy fpr but that shouldnt affect anything on startup I belive.
Obvioulsy I'm doing to little or too much of something, but what??
I have MAP, tach, Coolant temp and TPS reading on the laptop.
The standard problem seems to be burned out ignitors, they are not warm by themselfes but the nuts that holds it down feels pretty hot. Could that be it after all?
