Best TPS setting

[mr08353]

On PE Table, PE Throttle/pedal HOT, is there a "one size fits all" TPS percentage setting?
Ex. 30, 40, etc.
If not, how do you determine the best setting?
Would 50 or 60 be too high across the entire RPM range?

It's up to the end user really.

It's all a preference thing and how you have the other PE enable settings setup.

It wouldn't be a good idea to have a low MAP kpa enable of like 20kpa with a 30% throttle enable and a 1,500rpm delay because you'd be in PE like all the time. This is just an example.


I prefer to have the throttle enable on a GEN 4 computer at 60-65% because normal driving is anywhere from 20-50% durning normal driving. Then I like to have the RPM delay lower like 1,500 with a MAP KPA enable of 60-70kpa. That way pretty much the only thing that will control PE is your foot because past half throttle the revs will be higher than 1,500 and the MAP KPA will be higher than your enable settings and it's only waiting for your foot to go past 60-65% to enable PE.

This way you won't be wasting fuel when you don't need to and aren't in PE all the time.

You could also set it up to be a lower TPS enable above 4,800-5,000rpm too once you are already in the gas. Like if you had to lift or shift, that way because the rpms are already really high you don't have a small pause to get back into PE.

Good info. Thank you Sir.

With the above settings (60 throttle, 60 Kpa and 1,500) what would be good for enrichment ramp?
2.0 maybe?
And on my EQ Ratio I've got 1.141 all the way.
Would these be compatible?

I've just been using MAP for the most part and keeping throttle fairly low once over 2000 RPM's or so. Somewhere around 85kpa. Not sure these are the "best" but that's what I've done.

Have you guys had luck with this long term? I have found that I had to return these settings to stock as any change eventually causes a PCM code. Had it with a 2013 Camaro SS and a 2007 Corvette Z06. Any change was fine for a week or two but eventually threw the code. Back to stock and issues gone with no other changes made.

[schpenxel]

What was the code? I've never seen a code from this

[MMGT1]

Trying to remember off the top of my head...it was a PCM Error code. Happened on both, Ill open a file and find the code. When I see it in the list Ill know it...brb

[5FDP]

I've had my stuff changed for like 1.5 years on my current truck, never had an issue.

Just changing power enrichment settings shouldn't set any codes. Not sure how a pcm fault code like a P0606 would come from it.

[MMGT1]

Found it, got a PO606 code on both. Reflash and it was fine, two weeks later up it came again, both vehicles.
Changing the throttle position vs input did this as well. Couldnt change the throttle in either one or it threw the same code

[5FDP]

Under Engine > Power Enrich > PE throttle/Pedal > HOT, changing that will not cause a P0606.

Perhaps you are doing something else to cause the code?

If you are changing any of the desired throttle area tables, then yeah I could see that being a problem.

[schpenxel]

yeah the throttle map tables are the only ones I've ever seen cause that error, nothing related to PE

[GHuggins]

If you change anything on the base torque calculation side of things and then change some of the fueling it can cause the p0606. I'm referring to air mass and coefficient tables as far as the torque side of things goes. Then as previously stated, the dd tables. P0606 can also rarely pop up if the VE and maf don't agree close enough. But that usually coincides with changing some of the other tables in unison.

[mr08353]

Lol. I didn't mean to create a code argument. What about the other settings I referenced above? The ramp and other one? Would those work? 2.00 and 1.141?

[5FDP]

1.5 to 2 is fine.

1.141 is 12.86 AFR based on 14.68 stoich. It's up to you if you want to run at for WOT or the car will let you know if it can handle running that AFR. Try to pick around 12.5 AFR for starters and work on it from there on a NA motor.

I don't know what your stoich ratio is set to but on a 14.68 it's around 1.174 for 12.5 AFR.
