Looking for the speed scalar for a 93 stock or with 17" rims. Mine is way off for some reason after chipping the pcm.

Thanks.

 

just read your old prom for the data

 

The stock chip is soldered to the stock board and I dont have the 28 pin socket adaptor. Anyone have a stock 93 bin?

 

No 93 bins around?

Well I went ahead and ordered the Memcal adaptor, and will post the results.

 

Well, I pulled the stock bin from the car and found out it had the same Road Speed Constant as the one I was using to tune with??? That not making sense I just made all my adjustments to the original stock bin and flashed that file. After that everything was tuned right and the speedo read correctly. Not sure why the other bin didn't work but all is good now. If anyone is interesed in the stock 93 TA M6 bin PM me.
