Hi all. I have the same problem with my FG NA + T. Did anyone find a solution?? Mine hunts sometime at idle in gear ( usually at the traffic lights) and sometimes with the cruise set around the 100km speed. Seems good on a flat road set at 100, but if going up a slight hill it will surge a few kms past the set speed then go a few kms below etc. Gets so annoying I usually turn cruise off. Any help would be much appreciated. Cheers Jason.

Perfect Thanks.

Hope this is not a stupid question? But how do I check my current credits balance? I have looked all through check my account etc. but cannot find a credit balance for my account. Thanks in advance. Jason.

Yes . I will try them and report back.. It all helps for us to know and may help someone else. I would be only happy to share and give back if I can for the help i have received here. I will try them tomorrow. Thanks, Jason.

Excellent advice once again. Cannot thank you enough. Knowledge is king with this stuff and i am just getting started. But I have already fixed lots of problems I had after the last tuner screwed things up, so I am well in front so far. Cheers to all for now. This little problem is solved.

Hey guys. I didn't have any luck getting that tune to work you modified for me Puffwagon. Don't know why something in it ( same when using the original Turbo tune ) just is not compatible with the PCM. Just get trans fault and the U0301 locking it in first gear.. BUT. I did what you said and now all is great.. I had to end up turning the Rev limit to 6600 as well as increasing the pressure on the trans shift etc. Now it will shift nicely on a WOT sprint from stand still. Very happy am I...... Really appreciate all the advice and another happy PCMtec user.. Thanks, Jason..

Excellent. You guys are the best. Let you know how I go..

Thanks so much for the time guys. No, the NA trans was working perfectly until I started getting up around 18PSI boost 600HP. So I just thought ok I am pushing the NA trans past what it wants to deal with. So purchased excellent FG1 Turbo trans and thought that would solve my problems. But after having to load the old NA TCM tune to get everything to be happy. I have exactly the same problem. Its weird, but still very drivable. Just cannot give it WOT from standing start as it will refuse to change out of first and just bounces of the rev limiter until I lift off a bit then all good. I will load the tune you have modified for me ( thanks so much ). And if still the same I might turn the boost way down just to see if everything goes normal. Really appreciate the help. Cheers, Jason.

Thanks Bill. Full read below. This is my current PCM and my old but modified TCM file from the NA box loaded to the Turbo box. I cannot get the original Turbo TCM file to pair with my PCM and yes, get the U0301 code software not compatible with PCM. Thanks, Jason. Full PCM TCM 7723.tec

Hi. Just did another read and this is the latest TCM file I am using. The one above is just my original NA tune working on the Turbo box. Thanks. Jason. NA tune on turbo TCM 7723.tec

Live and Learn hey.... Yes that would have been much easier than the way I did it.. Appreciate the Knowledge very much. below are the origial ZF Turbo tune. And my NA tune that works with the new Turbo TCM in the car. Thanks. Original Turbo TCM file.tec First TCM Turbo file working.tec

Hey Guys. Hoping for some more help. I have checked the auF1692 to match ZF03987. And they are both 4, So I guess they match but still cannot use the Turbo tune, same transmission fault.... So I copied my NA tune back after painstakingly going through pretty much every parameter and changing them to match the Turbo tune. Everything is great, except I have the same problem as with the NA box. I hard run from stand still WOT and the trans wont shift out of first and engine just bounces off the rev limiter until I lift my foot a bit then it all goes back to normal and shifts ( same if trying to do it in manual shift mode ). If I do the same standing start with only around 80% throttle trans works perfectly. Also after the run and it is staying in first gear launch at WOT, if I scan for fault codes it comes back with "P0701 Transmission control system - range/performance " Which is what I was getting before when I had the NA ZF box in the car. I changed to the Turbo ZF because of this and thought I was just going past the limits of the NA box.. But now still the same thing. So only thing the same really is the NA tune is on the Turbo TCM now.. Must be something in the tune that is triggering it?? What do you think?? Thanks in advance. Jason.

Thanks again guys. I will give it a go tomorrow for sure and report back my findings. All working sweet with the old NA tune file and changed all I can see from the Turbo tune across. But will do what you have suggested to the Turbo stock tune file and see how it works. Nothing to lose now as I can just go back to what I have done now. Cheers guys. Jason.

The other clear difference is the stall/torque converter. First pic is the Turbo and second is the NA. So just for no confusion, yes the rusty one here is the TURBO one from a wrecked FG. And the clean one is the NA straight out of my car. Hope this may help someone out.. Cheers, Jason.

Hey. Just done a change out of NA ZF in my FG to a Turbo box. Thought I would puts some pics of how to tell the difference so now one gets caught out. First is the trans itself. On the right/drivers side there is a barcode/white sticker that clearly has TURBO written on it. see pics below. Next pic is of the same white sticker on the NA box.
