5.0 Microsquirt start up help

ultrabluevert · May 28, 2019

Looking for some ideas for help with my tune. Car starts but stalls unless I hold the throttle and let it warm up. Any tips on where to start adjusting?

Combo is a 1990 Ford Mustang GT with a Microsquirt.

306 with Edelbrock RPM heads, 1.6 Rockers, Lunati 51014 Cam, Edelbrock RPM 2 Intake, Accufab 75mm TB, 60lb injectors, Vortech S trim with intercooler.

New to tuning and Microsquirt so opening to ideas to help out. Tune file is from some other local folks with semi similar combos.

Thanks!

Welcome to the forum. Glad to see another MS User

Please post the tune file and a datalog for us to evaluate.

Thanks! Attached is a data log from a cold start where I was having to apply throttle to keep it running. Let me know what other type of data logging I should do to help gather more intel.

What you want time off? Certainly interested in remote tuning help and class on proper use of the software and not break stuff. I suspect I may be approaching the magical range when stock blocks could decide to split...Visual in case that provides any inspiration.

Nice looking engine bay!! I saw your PM and will respond with the information you need.

Thanks again Steve for your time and patience this evening getting it to a good place. Starts and idles like a champ and have a much better understanding of Tunerstudio and the settings. Even better have a plan going forward to get the tune the rest of the way there. Highly recommend a session with Steve to get your car in a safe place.

You should start your own thread and I will respond to it. Create it in the digital tuning forum and I will get a notification.

Just curious how you like that lunati cam? Just installed the same one in my combo with trickflow trackheat and brodix st 5.0 heads. So far it seems to work pretty well for me
