Tuning with a aftermarket wheel with the oem ecu?
With a oem rev limiter and running with a aftermarket wheel what performance gains would be expected?
I would be running a ET HB WHEEL.
Besides needing a boost clamp what else is needed?
I already have the rrfpr installed.
I have been told that the oem ecu runs rich,so would fuel need to be added?
Would it be able to turn a 160 magnum 12 vein pump?

I dont know about the pump, however i do think you gonna need a fuel regulator, i have seen ppl with E1 run 79mph with stock ECU. @yamahamiamiski. Also you should know that Riva specs on Boost clamp is 17 pounds of boost MAX. you can contact them and see if you can run more. but on their website it says 17psi max.

I have the stock ECU and Injectors and an E1 wheel on my 08 FX SHO. Here is my setup and what I ran:
78.9 MPH @7680, Yamahamiamiski, 08 FX SHO, 195 lbs, 95air/?water, fresh water, sea level, 1/2 tank, one click up trim, Riva Power Filter, Riva manifold upgrade, Fuel Pressure Regulator(75psi) 93 octane pump gas, Boost Clamp, E1 SC wheel, Upgraded R&D SC shaft, Riva Powercooler, HKS BOV, Solas 15/22 prop repitched to 15/26ish, Anti-cavitation cone, Riva thru-hull exhaust, R&D intake grate, Riva rideplate, stock ECU/Injectors.

I have the jd intercooler(type14)
The intercooler is capable of keeping the AIT cool.
The speed i am looking for is 79+mph like what i had with the R2/C3. I was able to run 79.2 consistantly in the summer @ 8400 to 8500 rpms.
Which was with a 85mm exit nozzle ring, unmodded R&D rideplate and the R&D steering nozzle.
If i can get those numbers with a oem ecu that will be awesome.
Definetly want to be in the high 70's.
I do have a oem plate with jims mod and a modified oem exit nozzle to help with the top speed.

Just curious, but what's the reason for going back to a stock ECU? The thing I remember most from the pre-reflash days was the PITA of constantly having to change prop & nozzle setups to keep off the rev limiter every time the weather changed 10*.
