i set rice-etr up with a flow rate and he reported back everything is great.

stock computer, stock bottom end, stock heads, thunder cam, 58psi fuel at idle, stock injector offset.

i dont see what the big deal is?

I got my motor started today...gotta get the idleright with the camand then i will put in my 60# and let you know how it does

BIGBOS

Sounds good, keep us updated

I should have mine within the next day or two and I will throw them on and post the results.

Can someone post their injector table with these. I can figure it out on my own, but it would be nice to get a starting point and avoid reflashing 10 times.

I talked w/Andy from A&A corvette, here is what he suggested......

He replied with:

I have these ina 346 motor with no problems.
Try these IFR numbers. 5.83 5.87 5.91 5.94 5.98 6.00 6.05 6.07
6.11 6.15 6.20 6.24 6.28 6.31 6.33
That's what I have in this car and it idles fine.
Thanks

Those #s seem a little odd to me. I have some 42s in my car now and my #s are bigger than that.

if you guys want the flowrate for a stock static fuel pressure i'd have to work it out.. just a simple calculation

i agree i dont see how in the world those from a/a can be right, would be way off for mototron 60's unless hes running something like 40psi fuel pressure.

I was temporarily forced to run these 60#er's at stock fuel pressure because i had not done the fuel system at that time... MM gave me the IFR # to put in, the car idled/ran fine... with no changes to the offset.

Yeah, those flowrates posted are closer to 42's than 60's. Just to clarify, the car idles and drives good, but it has negative fuel trims and is idling at 10.5-11 air fuel.

RICE ETR- what are your fuel trims and inj PW at idle?

Yes those are near 42's.I would figure 60's would be 8.??..

they are i'll post up the correct numbers when i get home..

anybody using a referenced regulator that would like a flowrate pm me.

Jim, do you think you can get these puppies to work fine in my setup?

qqwqeqwrqwqtq

Well, I'm running them in a customers car open loop and everything seems ok other than running a bit fat at idle.

QuickSilver2002

Well, UPS showed up and I got them in my car tonight. Man, the bodies of these things are small compared to my 42s. . Idle was almost perfect on my first shot at it. LT and ST trims were almost 0 WB showed about 14.7 with some movement. I still have some tweaking to do, but I would say these idle pretty nice right out of the box.

I'm seeing a 1.8ms pulse width at idle once she is warmed up. I set my flow rate in the 9.2 - 10.0 range. I actually have a refrenced regulator and run about 51 psi at idle (I need to flatten out my table a bit).

Sorry for the delay.... when i had stock fp, i set my IFR to 9.44, now with a an adj FP reg. i put in the IFR that MM gave me (as mentioned simple calculation) which is 7.871 all the way across.
I didn't get the PW with stock fp, but now at idle it is 1.79-1.86ms with L-trims of -.8 to -2.3 at idle and cruise... and of course they always lock in at zero. I am going to leave it as these l-trims are as good as they were when i was N/A with stock injectors.

I had 4's and 5's in my motor with 42# injectors (GM 3800V6 38#). To make the 75# injectors work, everything was adjusted to 8 across the board. Andy recommended 9.3. I'm running 62psi with racetronix and BAP.

Note that the 8's were entered for a rough tune, it needs to be fine tuned as soon as Nick N. gets his dyno running.
