Mrkiiitattoos had this exact problem. And I belive his ecu was burnt on that side of the board from a short at somepoint. maybe he can chime in on this. I think he had it fixed at drift motion
What harness do u have. Mine was out of a chaser and the wires for the ck codes were cut. I have mine running to a toggle switch. . U just have to locate the wires. U may be able to trac them back to ecu and ck codes that way
just a long shot but have you looked over all the fuel lines for a crimp in it. and how is your fuel filter? and what about the screen onthe pump in tank, is sounds like your starving for fuel.. also can you take out the resitor pack and run the stock injectors to see if this help out the issue?
Look at the wires going into the water temp sensor.. I had this problem close to yours not to long ago. Turned out to be half broken wires to water temp sensor. Replaced them and all was fixed
No I can't confirm. All that matters is that its a 3 wire narrow band o2.. the ecu does not car.. it can be any 3 wire u want.. I run the 5o cuz its cheap and at every part store.. if the car that will trigger o2 code.. what are the mods.
white wires are heater.. blk wire is not ground.. its o2 signal. sorry i did not catch this sooner
And did you clear the fault codes in the ecu.. it will store o2 codes.
Also. If the car is super rich or lean.. it will trigger a o2 code. What's the afr
Ck to makes sure the hose is not broke at the map.. and that their is no broken wires at the map.. or where the clamp was.. sometimes the nipple will break off of the map
I don't think you need a fcd if your afc is tunned correctly. How boost are you making. I would put it all back to stock aqnd start their. I got a little off. . We also need to know what harness u have to say what pin is for the map
But on a side note. I run no fcd and car makes 23 psi with no...
