Speed Density proms? (90-92)
I repinned my L03 harness to work with a 350 TPI that was set up for speed density rather than MAF. The original memcal and prom are attached in such a way that I cannot remove the prom to replace it with my new aftermarket prom... Do I need to have a new prom burned with the chip attached to the memcal?

Thanks.
This is irrelevant but does the 2timer he sells allow you to run two chips and change them without dropping the ECM?

Not two chips, but two BINs in one chip. The wire is used to select which of the two BINs is actually used by the ECM.

If you wanted a dip socket like the D2 soldered into your memcal send me a pm I will be more than willing to assist. I have never seen a aftermarket prom sold bye itself so , hypertech, jets, ads all have used a piggyback like the G1. The g1 fits the 165 case better than the other adapters.
