Hot start its ok but after hot leave car off for 10m and the problem comes -22 degrees again

Sorry to wright on your conversation, but i have a similar issue. I have mycar tuned and and runs fine but my car doesnt start when cold. Takes time to start. I checked my pfc comander and the temperature sensor shows like minus 22 degrees (-22°c) wich is impossible. Try to replace for a new one and same problem again. Do you guys have any ideas to sort this out please? Thanks

yeah im back friday so i will forward something through Hi again status. I tryed the map you sended me and made some adjustments and car runs fine thanks alot. Now my exhaust manifold is cracked lol. I am looking for one more resistant then this one. And i have a problem with my ecu 2 pin temperature sensor. Car takes time to start and when start i warm up for a while and when a turn engine of for 10m the reading in the ecu is like -22 degrees wich is impossible. I bought a new one and it does the same thing any ideas? Thanks

Ok mate cheers. I am doing the injectors at the moment. I Done 43.5 to all my injectors but the car is running rich on my wideband. I will try to sort my injectors latency cause by my maths is +0.24ms But the car is steel running rich so probably it is a diferent latency. Cheers

Hi there mate. Are you in the same situation as i do? Are you trying to map your apexi pfc? What type ecu you have and car? Cheers

By the way i sended to you mail my mods. I was wondering if i, using a timing light do the 15 degrees advance on the CAS sensor or do i compensate in Apexi PFC ignition avdance sheet? Thanks

Just let me know if you received my email with my mods thanks

I was wondering is the latency on the injectors left at zero? And the diferent value set on the injectors is there a reason? Thanks

I have loads of carbon on the plugs. So it seems to me that i have a lot of fuel added to mixture. Very rich mixture. But it is a bit dangerous to lean the mixture. I will try small increments adjust to the mixture and i will see how rich is the mixture on my wideband. Actualy is showing something like 9.4 on the wideband

Thanks mate for your help. Very much apreciated. This fórum is realy a most with very good People and happy to help. I will logo my datalogit to my pfc and aply those numbers to the fuel injectors sheet on my pfc d-jetro. Thanks i will let you know how was it after that whith the mixture. As long as doesnt knock much and doesnt run lean i will be ok

Thanks was what i saied but they saied that they Never Done an apexi and they dont want to take the risk. About the fórmula i found it but it doesnt say what latency are they rated. I even found a injector chart but no densos orange 850cc top feed

Hi there mates do you guys know the latency for r33 top feed 850cc orange denso injectors? I am reading these topics cause i am trying to understand how to map my rb25det pfc d-jetro ecu cause where i live no one knows how to remapp an apexi. The tunners here only deal with motec haltec or AEM ecu. If you guys can help me with this issue will be much apreciated thanks

Hi there try and check the MAF sensor first. Then Try the coilpack loom. Then check for vacuum leaks se é if this helps
