HJTRBO,

A bit of progress today. Tried your mods and it ran pretty well. Idle hung a bit high, but that's OK. The transition from P/N into gear was good. However, it still had a hard stall when...

Might start a thread. Not sure how putting a High/Low signal into the A/C pin could be used to tell the car it's going into gear? Unless you're saying to use the A/C table provide the extra airflow...

Thanks, HJTRBO. Yes, I looked over your changes and can see that it will be aggressive in Park. Will take some playing with it. I'm eager to see how the big change in Follower Torque is going to...

HJTRBO,

Thanks, again, for the edits to the cal file. I need to find some time this week to test it out. Going to have to wait about 5 months before I can get it back on the road and see how...

OK--finally made some time to do more testing for this stalling issue when blipping the throttle in gear.

I tried Jeff7577's suggested changes in the file he supplied (THANKS!) and things got...

Jeff7577,

Finally got a chance to look at your suggested changes. Interesting that you cut back on the spark retard/advance in the Adaptive Overspeed/Underspeed tables. And the values are zero...

Jeff7577--thanks for taking the time to look this over and to recommend some changes! I'll take a look at this tonight. Hope to try it out Friday or Saturday.

Thanks (again!) hjtrbo--great info, there! We just got 6" of snow (I'd gladly switch placed with you now...) so I'll need to wait until Friday when it's supposed to be warmer to try this out. The...

Just finished the Gen IV Tuning epic post from BigMike42. Really helped me to solve a problem I had with the engine stalling when dropping from P to R/D.

So one big issue left to solve. When I'm...

BTW--in case anyone is reading this and wants to read the idle tuning guide for Gen IV, I found BigMike42's "Gen4 idle tuning guide" here:

Thanks, again, hjtrbo!

This is gold! I can't seem to find a PID for the Base Airflow Minimum, but I'm sure I can figure a way to pull the channel data into excel. Time to give it a whirl!

...

hjtrbo,

thanks for the details! I'd like to ask a few follow up questions.

do you happen to have a link to the russK post with his GEN 3 instructions?

Doesn't dynamic air already include...

Looking for advice from the tuning geniuses here!

doing some tuning work on a supercharged LS3 crate engine with an E67 ECU. I'd like to fine tune the Airflow Final Minimum values to see if that...

5FDP--thanks for the info! I believe "1" indicates full reference of the Low Octane tables and "0" indicates full reference of the High Octane tables. Software engineers are funny people; you would...

Is there a PID or some other indicator that will tell me whether the E67 ECU is referencing High or Low Octane tables (e.g., Engine/Spark/Advance/Base Spark Timing: High Octane and Low Octane...

Relative newcomer to HPT but experienced with other EFI systems. I've got an E67 controller on an LS3 crate engine running the GM ASA cam (Duration @ .050" Lift( Deg): Intake: 226 / Exhaust: 236,...

thanks, kevin87turbot! Good info. Yes, I had Chuck at B3R near Cleveland (my area) modify the tune for the supercharger. it generally does fine, but I see ST and LT trims in areas that could be...

Well, I've learned something--no wideband sensors. Time to go get an external unit. Thanks for your answers. I've spent quite a bit of time reading the forums and looking at YouTube and most of...

Noob to HP Tuners so go easy....

I have an E67 crate swap ECU (OS 12638778) on an LS3 running an Edelbrock supercharger. Trying to tidy up fueling to bring the ST and LT fuel trims into line.
...

Thanks, WAK.

Do you happen to have any info whether the STIT and LTIT channels are available in the E67 OSs? Sure would make it easier to know what is needed

I'm currently trying to pull...

(Re-Posting to the correct forum...)

Hey, Folks! I'm a noob to HPT but experienced with other EFI systems. I've got an E67 controller that came with the 525hp LS3 crate engine ('67 Impala with a...

Sorry folks--just realized this is the GEN 3 forum and the E67 is a Gen 4 unit. Moving this post to that forum. THANKS

Hey, Folks! I'm a noob to HPT but experienced with other EFI systems. I've got an E67 controller that came with the 525hp LS3 crate engine ('67 Impala with a 4L80e using a standalone TCI...

New to the forum--please let me know if this should be posted in another area.

I have a client that is looking to pair an LT5 with a 6L90e transmission. GM offers an E99 controller which I'm told...
