Default 4+3 Tuning

Has anyone tried to use the ARAP bin on an 88 with a 4+3? I got rid of my cold start injector when I installed the super ram, and with a couple other modifications I need to adjust my PROM. I want to use the ARAP bin but I want my overdrive to work too. Any one else been in the same boat?

Thanks,
J

Me. Thankfully there is a forum member (Red88Vette) who claims he should be able to add the overdrive functions into the ARAP code. Our other option is to go to manual overdrive control.

I would recommend using the APYP code. It is meant for a manual transmission. The ARAP is for an automatic transmission.
And yes, I do have the APYP code modified to work with the 4+3 transmission. It has passed all of the tests on my 88 Vette. Email me if you would like to try it.
