I thought I emailed them to you? If not, I still can... Whats the addy? What wideband you using?

could i get a copy of the histogram, or could the setup be posted?

PM me your email I got them

I have a few questions about the procedure

Turn off Closed Loop operation
a) To do this, open your current calibration file in the HPT Editor.
b) Go to Engine>Fuel Control>Open & Closed Loop
c) Open the ECT vs Startup ECT table
d) Set all the cells to 255
2. Set the target AFR *(WHAT IS THE TARGET AFR?????)
a) Go to Engine>Fuel Control>Power Enrich
b) Click on the Base AFR vs ECT
c) Set your desired AFR at each particular ECT. *(HOW DO WE KNOW WHAT OUR DESIRED AFR WILL BE FOR EACH ECT?)
d) Open the Mult vs RPM and set the multiplier for each RPM to hit the target AFR in that RPM cell
3) Turn off any injector pulsewidth modifications
a) Go to Engine>Fuel Control>General Fuel
b) Click on the IPW Multiplier vs RPM table
c) Set the entire table to 1.0
4) Make sure your injector constant is correct and working as desired
5) Save this file as VETuningCLDisabled.hpt (or whatever you want, just don't overwrite your working tune).
6) Go flash this file on to your car.




GMR has got nothing on this

Will someone possibly just put the histograms on a host?

If someone emails them to me, I'll host em.

Here are the ones I use.
Low RPM
High RPM
Coast Down
Idle

note that the RPM ranges are wider than the tables

also note that they are setup using my AEM Wideband 02. You will need to change the PID to the AFR error you setup for your wideband.

Well, thankfully I have the pro interface and also an AEM wideband. Just don't know how to connect it to the interface. Just the 0-5 wire?

there is a diagram in the help file for HPT that shows you how to connect I/O to the MPVI pro interface. the HPT help file has a lot of very helpful info, it's not the typical BS help file.

maybe a dumb question, but when i have the config file flashed my cooling fan doesnt work, and the car gets a lil hot by the end of my 30 min trip, what do i need to do to fix it, on the regular cal it works just fine. Thanks for the input guys, i feel retarded no knowing this lol

Just got the car retuned yesterday, street tune. Tuner found our ECU really difficult to tune. 1 table vs 30 for a vette for example. Got a good street tune I think. When it came to timing, I am at 28 at 6 RPM without KNOCK. Never made it on the dyno for WHP numbers so playing with timing was a guess as far as getting me more WHP. My AFR across the RPM band was 14.5-15 and 12.7 at idle. I know nothing about tuning so I wish I had printed this sticky for the tuner. He adjusted all he could, but I wonder if there is something this sticky could have told him.

I would love to talk about it to any of you guys (PJ, NEWT, SHIFTED etc). Call me please. 813-924-4219

Thanks!

That AFR is way way off.

Your Afr should be 14.7 ish at idle and cruising and in PE mode or Wot (however he tuned it) should be around 12afr.

Yea those AFR's are off by a wide margin. You are missing out on all kinds of spark advance with your AFR up there and throwing money out your exhaust running that rich at idle.

Thanks guys. I've emailed the tuner. I'll try to get it back on HPT this week, hopefully without paying another $500! I'll keep reading the post for information that I will print and take with me.

One more thing guys, I could not find out to LOG INJECTOR DUTY CYCLE in HPT. The option isn't there! How do you guys do that? I'm not seeing that anywhere, still searching.

You better not pay another $500. The tuner gave you a @!#$ tune.
Re: HPT VE Tuning - The Easy Way

If IDC isn't a default option, your tuner should be able to set up a custom parameter based on IPW.




Re: HPT VE Tuning - The Easy Way

I had the wrong information. See below:

"Your tune was set for 12.9 WOT AFR and I brought the down some to 12.6 final AFR because richer is safer. Leaner can make more power, but will blow the motor easier. That's why I stay richer.
I really don't see much if again more gains for the car in the current set up. Under actually load of the car at WOT, I was able to see how fueling was and spark. You have 28 degrees of timing in the car now. It really should be a be to take much more if any, and if it did, its only work a couple HP and for as hot as its gets down here, to much timing is not good"

My next question is, does the ecotec motor like a lot of timing or should I have the tuner decrease it some? I think the car was more responsive at 26 degrees of timing instead of 28. Anyone have any idea on the timing parameters based on an NA ecotec? Also, the fuel pressure remained stock. Anyone think I should have raised the fuel pressure and tuned it accordingly. The shop owner and tuner didn't see the need to increase the fuel pressure, I seem to agree with them. What do you guys think about that?

One more thing. I am using the stock heat range plug (heat range of 5 from NGK - higher the number, colder the plug). Should I have got a step colder plug since my engine is hotter and modified (I'm not running boost but still?). If yes, and I replace the plugs with a step colder plug, that shouldn't mess up my tune I just had? What do you guys think?

Plugs are fine.

Timing without Dyno time to see the power between the 26 and 28 degrees no one knows.


Also this sticky is old and crappy. We have updated info in this forum on tuning.

I agree with the tuner and no reason to up fuel pressure.
