As a vette guy I have always been concerned about sucking up water as I speed down the hammer lane. If you guys don't have that concern - I have heard that the Vararam is an awesome system.

Let me know what you think.

I was also very interested in a graph. I understand that graphs need to come from a constant test - meaning test it under the same conditions.

So...let's get a run on the dyno....not change any variable other than the diablo programmer....and get some results.

I feel that I had much better ...

Sticky -

I had to adjust my ltft to -8 to get my numbers in tune like you saw. Now I would like to review my PE Table. One of my friends says that I have to adjust the PE table to get my low end throttle response but I read on this site that I don't have to do that if my ltft's are dialed in ...

I have a 2001 C5 Corvette and I added the twin tube intake, x-pipe and Corsa exhaust. After that I found some good improvements but I really found the quickest gains from the throttle body. After the throttle body I actually felt the difference. When I installed the dialbo performance tune it ...

You guys have done a great job segregating the forum into Manufacturer identification but it would be great to have forums like:

Corvette
GTO
Camaro
Firebird
Mustang
Charger
Etc.
Etc.

Otherwise - the Forum and Sticky really helped me work out my injector slope problems - Thanks

Thank you for all your help. This has been a good experience working with you.

I have a website that I just started www.portcorvettes.com

Click on the discussion board and Content to add things. I would really like input there.

The DSLogRedux program works on my other computer ...

I was able to install the program on my other PC. Sweet!

Is the next logical step to go to the Power Enrichment tune??

Not a Predator Question - Can I bypass the throttle body (the coolant running through it) so the incoming air temp is cooler?

Ok - I changed the injector slope to -8. It resulted in the following:

LTFT Bank 1 - 1.78%
LTFT Bank 2 - 0.00%

It did go negative a few times as the vehicle was going up / down a very modest grade.

I think I am getting quicker "throttle response" but it could be just in my head.

Also tried to ...

Thanks for the info on the tune - I will try it right now.

The error is DSLogRedux has encountered a problem and needs to close. We are sorry for the inconvenience.

If you were in the middle of something, the information you were working on might be lost.

Be right back with re-install comments ...

I will work on the reinstall. What about actually reprogramming the u7198 to accept the change to-8 for ltft?

No. I am using XP.

Ok. I understand that I am running lean and I need to make it run a little more rich.

1. I don't know how to actually change the parameter on my U7198 to download it to my car.
2. What other parameters would / should be changed in conjunction with this change?
3. I also downloaded the dslogredux ...

Thank you for the quick reply. I don't know how to post it. In addition, I don't understand what it is that I am actually affecting by changing "it" to -8. Can you give me a little background into injector slope?

Thanks for your time.

I have the U7198, v9r10 that I am using on a 2001 C5 Corvette. I have a K&N Filter, BBK throttle body and Corsa X-pipe with the Pace Car Exhaust. I have been trying to understand the Long Term Fuel Trim Bank 1 & 2 that I see "Sticky" talking about. I took my car on a run in 6th gear at 75 miles per ...
