Fuel level gauge issue after tune... Hi everyone,
New to the forum, and had a fuel gauge question. I have done a search and come up with nothing. I hope I’m posting this in the correct section, if not please forgive me!
The car is a `93 Camaro, with and 2000 LS1 swap with ECU, harness, fuel tank, Walbro 255lph pump, OEM fuel level sending unit, ect. The motor has been completely built, now a 402 cid, with cam, rockers, manifold, LSA 52lbs/hr injectors, adjustable fuel pressure regulator, and so on. The instrument cluster is out of a `97 and has been wired for the fuel level, and have done the fuel segment swap using EFI Live.
Anyway on to the question, the fuel gauge had been working properly giving accurate readings without any problems. The car was then dyno tuned using EFI Live, to where the ECU was converted to speed density from MAF and other obvious adjustments had been made. Since the tune the fuel gauge is now pegged on empty, up against the needle stop with the ignition on, and starts to move up with the engine running, but not close to the correct fuel level. I have checked to see if the correct fuel segment is still in place, to which it is. Other then that the car runs perfectly, but the gauge issue is bugging me. I hope this is clear enough to understand, if anybody needs any more info please feel free to ask.
Any help would be greatly appreciated.
Thank in advance,
Giancarlo
