Here's your correct injector flow rate for 60's.
Can't find the Motoron offset table for them.
Had it at one time.
Might be able to do a search on here or HP forum.
Injector Flow (lb/hr) 60.00105812 60.37500292 60.74664582 61.11602883 61.48319268 61.84817688 62.2110198 62.57175869 62.93042974 63.2870681 63.64170795 63.9943825 64.34512408 64.69396413 65.04093323 65.38606119 65.72937699

I changed my IFR values to what you posted and will see what changes with that.
Thanks

Thanks for pointing that out!

Motron 60's are ussually rated at 72lb at 60psi.

They tune fine on stock offsets.

Have you adjusted the OL equations???? Is the condition solely in OL or in the transitions from OL to CL??


Edit: Sorry didnt see you had it setup for open loop...

your injector data is off considerably.....

Change your OL Equation ratio to 1.0 for all cells from 68*F to 248*F and as far down as 75KPA.

Are the numbers Outcastdon posted better injector data than what i have?

Ive been messing with the OL equation ratio and it seems to have no affect. it still pegs out lean.
it pegs out lean now when i try to rev the car stationary.

im starting to think its the fuel pump and intake leak possibly...
i have an autometer fuel pressure gauge hooked up but it seems to want to work when it feels like it. when i key on it still builds pressure to 58psi...

i need to be able to see if my fuel pressure reduces when i take off and then "falls on its face".

Day to day the car seems inconsistant.

in this quick log i attached it shows a steady commanded AFR and you can see where the WB AFR reads ~18.8:1 through the idleing (if you want to call it that) and the pulse widths of the injectors range from 1.8 to 5ms and has no affect on the AF.

It wants to die when i give it pedal due to being lean i believe

Im thinking from when i switched from Gas to E85 originally i might have broken up old deposits from the gas in the tank and when i had E85 sitting in the tank for a will it cleaned up the tank a little and started clogging the fuel filter. Im going to check that out and see what comes of it...

I think your driveabilty will be compromised by the cam specs, you have moved that power band up in the stratossphere. I know first hand i just installed a 253*/260* @.050 on a 111* LSA in my 346 with 10.7 to 1 . The cam peaks torque for me at 5900 and Hp is 7600 rpm. I leave at 6500 and shift at 7500. Torque suffers until 5900 over a moderate size cam. I am tuning my low speed and driveability but you cant fix too much when the exhaust is residing in the intake around town driving.
