I have been working on an MG Midget (Don't Laugh ) that I have installed TBI from 1991 S-10 2.5 VIN A $94,ASWY calibration. I have IAC,and VSS included in the setup. These engines never ran good and I know when this calibration is correct it will run great (And also some guys bet me I couldn't do it). The engine is rebuilt because I didn't want to chase a proper calibration without a good base. The engine is running and I have adjusted to get a good cold start and idle. The engine likes 13-13.5 AFR for a nice idle. I have the ecm also controlling the cooling fan. I have not figured out data logging yet with TPro. I have Moats autoprom and innovate LM2 WB. Have both NB and WB in the exhaust.

I noticed the 747 with $42 can run a 4 cylinder TBI and has the ability to disable CL at idle and that will cure the idle quality problem. Also the $42 has allot more tuning information and tools available for the VE.
Another option is adding the NVRAM to my 165 ECM for the self tune capability.

Any thoughts about these options would be great.
