During my learning curve with tuning I found out that the my replacement 951 ECU does not have the circuit for the cold start injector. Though the 563 Computer that I took from the junkyard does. The only issue is that the 953 computer does allow for cold start cranking adjustments and the 563 does not other than with the cold start injector that my car was equipped with. Well after reading there was a ECU 937 that both has the cold start circuit and the cranking fuel adjustment. I located one and will become my main fuel ecu. I know these numbers don't mean much to anyone but Volvo made so many different versions of the same LH2.4 ECU and they all have some sort of weird difference in the program. Luckily there have been people who found or figured out most the differences and stuck it online. This should help me get this car to start under 30F on E85.
