+ 1 on EOIT, Dave Steck did us a huge solid with his info, major fix for driveablity issues and the dreaded startup fumes issue.

thank you that is not what I thought the answer would be but it is clear now how things work, I am glad to see good documentation.

Yes, however the point of my post was that connecting the first time seemed to have its own issues. First it would not detect the protocol, then it couldnt detect the vehicle then it couldnt identify...

After much time wasted trying to understand why I was continuously loosing more and more functionality I did a from scratch install which fixed nothing. Then I took my laptop to the car and after a...

Can someone briefly explain which does what now in 3.6. Having tried to gradually migrate from 2.x I find my HPT folder is full of files which HPT put there from previous installs and which do not...

So while maybe there are no dumb questions, this one is a near miss. Even though the sensor will be reporting values from 7.35 to 22.x its only going to display what ever values are between my...

So with 2.x I could use the wb setup graph to determine the values to have an HPT gauge display 10-18 AFR instead of the whole 7.35-22.xx range which corresponds to 0-5v. With 3.x I get the limit...

flogging this same issue today...research here indicated HCI engines are too rich with original tables. I agree with schpenxel on lowering the table to lean.
Main issue I see is the window for...

I'll have to get back with those. Until a few weeks ago I only saw this happen a little as I only had the laptop to monitor AFR while driving so I avoided using much throttle. Now I have an SCSS...

I should say my biggest issue with trying to improve things in the midrange is the lack of factors that seem to relate in anyway to the factors I equate with throttle transients=-evap factor, fuel...

First off, thanks for the replies, sometimes its hard to get more than a one line answer even if you post tune and logs. Power valve is as you thought. I picked up that VE is airflow which is fueling...

AH, well that is well above my experience level. My need is more in the line of not understanding anything beyond the cliff notes one line explaination of a table or setting within HPT...like you...

Dsteck posted EOIT calcs a couple years ago and while it didnt completely stop the raw gas smell for me it made a massive improvement. It probably helps that I'm now running 200 cpi cats but I did...

I had no idea I could get support from HPT....I'll probably flog it some more but expect I'll be asking them for help

Thanks, I read that but think its not very applicable to the E40 and maybe I am misinterpretting it but thought transient fueling on the E40 had more to do with temp transients from warmup to...

I'm seeing pretty big gaps(on the lean side) between commanded and wb measured afr. I'm not having much luck improving that without changing afr in areas I'm happy with. Steady throttle AFRs match...

wow, you're right...not what the log should be. That should have been a 45 minute drive...looks more like the first minute. Never had that happen before. Anyway, heres the cold start and run before...

Need to pass emissions...not interested in "cheating". She passed last time but I've been tweaking it for 2 years and pursueing turn key starts has lead to occasional map performance codes...

My...

thanks GMtech, mines a garage queen but I always log when I do take it out and with retirement coming this fall, I'm ramping up my use. I saw the ad for the new dual gauge Innovative and realized it...

What do the experienced tuners here think about dual WB's...worth the price of a second O2? Running an LC2 now so just a sensor is needed.
I'm tuning for driveability more than peak numbers as my...

IS there a post or page etc where we are told what you have to do to actually use 3.x?
After 30 minutes of reading logs only to get an error message saying I have to update config to interface,...

I tweaked cranking VE...magic. Fiddled with all kinds of stuff for a year, then tried this and a 10% change took me from taking a big bootful to start it and keep it running to turn the key and walk...

Thanks for the explaination, while it helps it also means to me HP should do more to label it as a tuning aid than a tuning tool. Now that it seems possible GM is claiming ridiculous things about...

As to it being number on an injector that would be a NO.
To reiterate, I'm asking in reference to the chart in the picture posted above, what does the numbers under the heading "Injector #" mean?

and the answer is, experiment and see:worship:
