Try lowering or 0 the top left corner 4 cells of the throttle cracker this should help with the revs hanging, then to combat any stalling increase the base running air flow in the temp range to stop...

Well i personally would like to say a big thankyou to Chris from HP Tuners, Mario from Autotechnique and Greg from VCM Suite for providing some insight to the HP product over the last 3 days. I have...

post a copy of your tune, what is your commanded afr and what is your PE set at?

Are your logging, if so you should be able to see if you have a bad o2 sensor, should be tuning it with a wideband

Try lowering the shift speed not rpm at WOT in the 1-2 shift

says the vid is no longer available Chris, did Mario do the job for you?

If you have a wide band, what brand is it? if it is compatible to be connected to your HP dongle then do it, if not- get one, are you running a maf, i only tune forced induction cars mafless/SD.
I...

We are planning a holiday to the U.S for LA and Las Vegas, what i would like to know is what are the hot spots in theses areas and what should we look out for? are ther any areas we should stay away...

I hope someone can shed some light on this!

I've had some issues in the past with electronic throttle, started off with fitting a Maggie and PWR 90mm t/body which entailed pulling the electric...

Check your scan, and look at the VE AFR error, it's way out, it's lean, get the figures between 0 and -7 and your fuel trims will be spot on, make sure when you tune this you turn off LTFT and o2...

Drop your idle speed back to 1050rpm and start adding to your base running air flow until it starts and idles on it's own, are you tuning with a wide band?, make sure it's not too rich/lean at idle...

Post a copy of your tune, sounds like base running air flow needs to be scaled back.

Is it better or worse when the engine is at operating temp?

The first scan needs some work in the ve table, it's too lean in some areas, is it an sd tune or maf? you can touch up the ve table using the narrow bands and copy - paste special - by 1/2 % in the...

Have you physically checked the throttle blade against what the scanner is saying?

I've started an SD tune on this vehicle that has a cam , removed the maf etc & usual codes but now when i start it it goes into safe mode and the engine cuts out and logs p0068 fault code, any ideas...

Thanks Russ, i'll re set the tables and let you know how i go

Dave

I've unlocked it and saved it so i hope it works

Sorry Russ, I'll re send it tonight unlocked

I'm having some trouble with a cammed car with the AC clutch engaging and disengaging rapidly at idle and light throttle, it's pretty anoying seeing as it's 40 deg c at the moment and getting...

Anymore info on the window switch set up, we have a few cars with H/C & Nos, I have tuned them with 5 deg less timing from 3000-6500 rpm for the gas, as we don't use the gas all the time it would be...

How is it on cold start?, it looks to me as though the base running air flow is too low at operating temp, this will cause idle issues.

Dave

I'll change the Maf fail to 13500 and see if that changes anything, didn't think of setting it to max because i was in SD but who knows what it will do.

Thanks

No not running Maf & 2 Bar, just 2 Bar SD.
I'll increase the running air flow and see how that goes, should i just scale the IFR down in the top end where i'm over fuelling?

Thanks for the tips
...

I purchased a new electronic throttle body (damn expensive at $1100), removed the TPS and the motor, swapped it to my 90mm T/body and ran it all weekend with no problems, I'm not getting too excited...

What about about the tune in the first post, can you open that one? if not i'll have a look and make sure i'm unlocking properly before saving it.

Just asking the Q of when the next release will be and will we be able to tune in SD for the VE Commodore/HSV, any chance of lean cruise for VZ LS2 also.
