Super nice build up

Keep an eye on the fuel tank bulkhead feedthru you built... and let us know how it works out. I experimented with essentially the same thing on a C5 and it failed miserably. Because the (97-03E) C5 bulkhead / sending unit assembly is on the bottom of the driver tank it is normally submerged in gas. The feedthru I made, similar to yours, weeped gas right out of the core of the wiring... to the point to where it would drip. Since your bulkhead is on the topside it may not be a problem... but I wonder if gas will get pushed up through the wiring if any positive tank pressure takes place... just a thought.

 

No, I built that assembly, the wiring connector is not only sealed with gas resistant sealant but also a gas resistant rubber gasket on the inside. all the fittings are welded and leak tested. Furthermore the tank is not baffled to push gas to the top of the sending unit outlet like other tanks out there.

 

Wow I missed all the fun!!

That looks like one helluva fun truck.

Thing def moves.

 

Good Job

 

Ok, Heres the issue. 50% throttle in 3rd gear. As boost builds bank 1 increases long term and short term fuel trim 13%, and 21% respectively. Bank two however decides it needs to decrease by -14% and -30%, Bank 1 pulse width is 10.4msec, and bank 2 is 4,5msec. Both o2's are in the down pipe next to each other and both read the same mV's. It starts breakin up really bad and going into alot of knock retart. When I floor it, it pulls out of it and enriches both banks up. If I let off both banks equal out as well. I'm using HP tuners, and can't figure out why it would be doing that. Its also got the MAF disabled.

help?

 

Where is your power enritchment set at?

 

damn. if both are in the downpipe i'd say one is bad. I ran 1 on the crossover from bank 1 and 1 in the downpipe which actually read bank 1&2 together. but I had the O2's disabled and just used them for reference. You need a wideband in the downpipe for sure.

 

Don't touch anything with the tuning, WOT and part throttle are controlled independently of eachother. you need to look at why the sensors are f'd up, if you switch the wiring does the ecu still add and subtract fuel at the same points? I'm willing to almost bet it's because you're running Mafless and part throttle is suffering.
