Hi all, having a lot of issues trying to get my 89 eunos started/running on the base tune provided with my ms2pnp. It’s basically a stock car with just the gm iat, and lc2 wideband. Sadly I bought the ms2 like 9 years ago and ran out of time before life took over and I’m only just getting back to it now. I’ve gotten the lc2 hooked up and working perfect then went to do the mega squirt and got it fitted everything reading and running in tuner studio but can’t for the life of me get the car to start and idle on any base tune being the one included on the ecu or any of the one available from diyautotune. Total noob in tunning and have been reading everything I can but starting to get a bit lost. Located in Australia if that matter and would appreciated any help I can get! Car cranks and splutters but won’t start and idle.

 

Did you remove the ST fuse? Any chance Australia had sequential NAs? I know the autos all were, not sure on other regions.

Attach your tune here, there are a number of options for the older MS2, lets look at the one specific to yours. Take a log while cranking too so we can see all the data your ECU is seeing.
