I'm going to check my IDC again Russ but the last time I did it was at 93 at 5800 rpm and I'd like to be able to go to 6600rpm. Not sure what it would be at that point as I've never taken it that...

Thanks for the replies. You guys must be getting tired of seeing my threads by now:doh:



I am going to try to richen the car up from 1100-1600 rpm and see what happens.



That's what I'm...

If I need to lean it out then why are my trims +25? Also, I thought the lower the 02's go the leaner the mixture is. Am I wrong?

Stock fuel pressure. 58psi I assume but it hasn't been verified. The car runs perfect save for some low speed bucking with the stockers installed.
Here's the tune for the 42's. and a 5 min log of it...

Do I have to do a write entire or can I just set the maf fail freq back to stock?

I know the resistance is higher and lower but what does it mean for tuning injectors? Are my stock injectors high or low impedance? I bought a set of 42's and the car runs terribly even with the...

I feel your pain. Subscribing.

Thanks Christian. I'll try and play with it and see what happens. As you pointed out, my cam doesn't have much overlap (1*) and that's why I feel driveability can be better. If I had a 24X/24X on a...

I'll give it shot Christian. How do I keep it from pulling fuel to maintain stoich?

Thanks for thresponse SS. As far as fueling goes I do have a WB hooked up but was not logging, just watching when the car starts to buck. Nothing really unusual. Car is trying to maintain stoich and...

Back from the dead. I went out tonight and tried a couple things with RTT. I tried using much lower timing values in low load/rpm cells which seemed to help marginally. I also tried pulling fuel in...

Excellent. Thanks Russ.

Any numbers with the new set-up? What size injector are you running?

Thanks Russ. I'm looking under Airflow>Dynamic Airflow>>Zone RPM boundaries and Zone MAP boundaries. Is that correct? If so, they read

RPM Zone 0-1 1000rpm (my car idles at 950) 45-55kpa I believe...

Christian, how are u? It's Chad from the Corvetteforum. You were the one I was referring to in my previous post. Thanks for posting up your tune!
Lowering my timing did help in low rpm-low-load...

I have seen this before also. A forum member has an identical set-up with the exception of a slightly larger cam and his timing is almost 50% lower than stock in the 1-2k zone. He is running a true...

Thanks for the responses. :cheers:

Russ, how would I go about LTFT Map and rpm boundries to match my cam and how can I tell that they don't match right now?

I am running the 1 barSD system...

Where do you look 1st? I have been concerned about this for a while now and I'm pretty sure it has nothing to do with my timing.
While rolling through a parking lot in 1st gear in the 11-1600rpm...

Let me know if you get you LM-1 and HPT to read the exact same values. My readings are always .3 or .4 AFR different between the LM-1 screen and my histo.
I've tried slowing down the read rate on...

Thanks Bill and Keith. I'm looking forward to trying it out.:)

Here you go Bill.

Thanks foff. This is the tune that is currently in the car. If you need anything else just let me know.:cheers:

I just remembered that I sent Keith a stock bin file and then I had to re-apply it. Do I have to use the exact file he sent me a while back or can I use any of my stock OS files? Sorry for all the...

OK foff. Just follow the re-write entire instructions again then?

Thanks for the response.

I have downloaded the latest version of HPT w EIO and purchased 1-bar SD over a year ago. Can I use the RTT function? When I look under license info. it only says 1-bar SD enhanced. Should it say RTT...

For sure. I tried that with my 42's and the car runs like crap. It's definately not as easy as plugging in a new ifr table.
