Thanks Paul! I will check it in a few days, the weather here is not really hot this few day.

I have done a dyno tune in the winter time, everything works fine. Until these day, the weather is getting hot. My car had no problem starting up in the morning or cold start. But warm start (usually I have driven it to fully warm up) and start it up after 15 to 30 mins, the idle will jump around and stall/surge. I have to keep the rev up a bit to keep the engine running and after 5 mins driving everything goes back to normal. Any advise where I should look in to? Thanks!

I think this link from paulr33 might help: http://paulr33.skylinesaustralia.com/docs/...powerfc-faq.htm

Hi Paul, I have installed HKS 600cc Injector on my R32, from your Power FC FAQ I could caculate the fuel adjustment. But I can't find the Injector Latenacy, would you have a chance to have the latenacy spec. of HKS 600cc injector information. BTW, your Power FC FAQ is a great document and help me alot on tunning this unit. ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 1989 Skyline GTR R32 HKS GT-SS Turbo HKS 600cc Injector HKS Racing Suction Apexi Power FC + D-jeto
