porsche 964 tpc supercharged vems ecu,
« on: December 07, 2018, 09:26:50 pm »
i ve done a nice project, i installed a tpc supercharger on my 964 1991, controlled by vems ecu,
all was going good, but suddely i realized that the mixture is too rich on idle, and that on deceleration from high rpm, the mixture is rich (10) i realized that the vaccum is not going less than -0.5 which is strange, i checked all vaccum lines there is no leak, is it possible to be fpr? does it affect the vaccum?
this problem happened suddenly!
i will be glad to hear from u guys

Hi.

Please provide a log of the occurance,
I donĀ“t know what you mean by -0.5 ,

you FPR could only affect vacuum readings if it was leaking air pressure
