Hi friends I have a problem which raised from my new Greddy Ultimate programmable support ECU. So I canceled my AFM and I could run my engine without this part but I don't know the best mixture of AFR. Please inform me about this problem. Perhaps you have a base map which I am able to use on my Greddy for my car. So my car's spesific ; injectors : Primery 550 RC - Secondery 460 Stock , Turbo : T70 constans pressure @ 0.7 bar , AEM UEGO Controller , Greddy EGT , Engine has been turned 13B N/A to 13B Turbo. If you have any information please share with me. I don't know how I will adjust the Ultimate for secondary injectors... This is the real problem I have I couldn't run the secondaries Thanks All of you my friends...
