    Reflash back to stock?

    I did a transmission service shortly after I got it, so around 25k km ago.

    I know ideally it'd be nice to tune both engine and transmission but how does stock transmission tune behave with tuned engine? Apart from it being super slow to shift.

    Moreso if it starts to slip, you do the service and reset the tune to whatever you had before. I had slip issues and the transmission wouldn't adapt after I serviced the transmission, so I just flashed stage 2 again and that fixed it.

    I understand. Thanks for the clarification. I would be going to just a stage one tune from bone stock

    But this is good news. Do you have stage 2 on your transmission as well? I'm guessing that's just way more aggressive shifts than stage one

    I'm glad it worked out for you and you figured out how to sort it

    I might pull the trigger on the stage one whenever the next sale is on

    I’m running stage 2+ and it’s phenomenal! Power and sound enough to keep my grin from ear to ear on every drive. No issues at all.

    What fuel you guys running ?

    @Jake, with regards to logging, i only have OBD11, would that have sufficient logging? in the case where our local fuel sucks and would need tweaking ?

    It's possible, would need to talk to tuning support. I know they prefer VCDS

    I’ve been running stage 2+ for a couple weeks now and not sure if it’s adapting properly. It’s almost like the performance tune very abruptly comes and goes at certain throttle positions and/or RPM but it’s not consistent. When it kicks in it’s a surprise and it pulls very hard, but it doesn’t correspond to demand or engine load.

    Worth noting the first time I did the flash I only had stage 1 and 2 in the drop down menu. I did the S2+ TCU tune, came back to the ECU menu and the S2+ showed up that time so I re-flashed with that. Also I chose 91 octane not remembering if we consistently have 93 here but confirmed I’ve been exclusively running 93 since the tune. Should I just re-flash to the S2+ 93 octane option and see what happens? Do I need to re-flash TCU after?

    I was noticing some transmission slipping before the tune and it doesn’t seem to have affected that other than shifts are more firm at higher rpm. I’m thinking mechatronics need to be replaced. It runs like a CVT in 2nd and 3rd gears, even in manual mode. Again, this started before the tune. I didn’t expect the tune to fix it but hoped it would.

    @Jake@JHM - do you know if sales can be retro-actively applied ? or is there a way to get notified when sales go on? saw that 20% sale for tune but by the time i called my shop it was already gone. Seemed like it was supposed to go for a week in nov and then some extra sales but i see no sales now...

    They happen every weekend up until black Friday/cyber Monday. However the purchase would have to be direct to us, not your shop in order to get the deal.

    @Jake@JHM, do you offer a E40 tune for the C6.5 3.0T? I am at Stage 2+ with DP and about to refresh my HPFP and trying to determine if I should upgrade the Piston while I have it off the engine. Thanks.

    So I've purchased JHM's C6 tune for my 2010 3.0T and am looking forward to trying it out. What are people using as a power source when flashing their ECUs? JHM recommend a 40amp charger, but I've seen recommendations for 10amp up to 50amp. What have people had success with?

    Where I am in Australia 40a chargers are not plentiful and fairly expensive, and would be rather surplus to my needs most of the time.

    Anything that can insure your battery voltage stays at 12v+

    While risky, you can flash without anything if you have a healthy battery. At your own risk of course.

    People have hooked up another vehicle with jumper cables, portable jumpers, etc.

    When I did my Stage 2, and 2+ tunes for the ECU/TCU from JHM, I put my NOCO charger on the terminals in the engine bay.

    There were no issues during the tune upload or after.

    We don't have a rental program unfortunately. Though you may be able to find someone locally with a cable who you can borrow from

    @Jake@JHM - thoughts on running 187mm crank pulley on stage 1 tune ?

    I got a good deal on a 187 crank pulley so i bought it; but I don't really want to do anything beyond stage 1 (for now) since stage 2 and above require supporting mods.

    Won't be an issue. Our software will bleed off the excess boost it doesn't want

    Got the stage 1 ECU + TCU :D man this car feels alive now. Can't believe how neutered it was stock sheesh.

    I only drove it a little bit today as it was rush hour and no space to do anything; but i will report back after i do some more driving.

    A little update; went for a drive and tried out different shifting combos at different gears, speeds and rpm’s.

    Regular D driving is definitely nicer and more responsive, no issue with any shifting. shifting up is definitely a bit more aggressive and can be felt more and shifting down is very quick. Shifting up can be almost imperceivable if I do a quick lift off when I want it to shift. It’s like shifting with my right foot.

    Driving in S is bad ass. Shifts harder and faster and no noticeable issues when near or at WOT. Have yet to red line in any gear since I need to more room.

    Now for the unfortunate part.

    In Manual mode, 4th gear at around 50% throttle, 3500rpm tried to shift up into 5th, rpm jump to let's say 4000 and then clunks down and stays into 4th.
    I was able to reproduce it 3 times. On the 3rd time I did more than 50% throttle, clunked hard but stayed into 4th once again and got tranny warning about an issue and to drive as normal. Went into limp mode. Pulled over restarted the car and it went away and went back to normal.

    Thankfully this is not a use case that I'll ever find myself in since the speeds are too great and rpms too high but still unfortunate it happened.

    Glad you like the software! Keep an eye on the shifting behavior with the transmission.

    @JAKE@JHM - are there any issues just running the JHM downpipes with everything else downstream being stock ?

    Based on this reply I'm assuming the JHM catted downpipes fit with the rest of factory system?
    Don't have the funds to fork out the full exhaust, so I'd prefer to start piece by piece.

    Still running factory exhaust behind that and no other mods or tuning. She’s loud. I need to re-check all the clamps etc. but it’s very harsh above ~2k RPM.

    Is JH still planning to offer a complete 3” system?

    It will work just fine All of our systems are modular so that can work with the OEM counterpart. Today is the last day of the sale FYI

Shifting up can be almost imperceivable if I do a quick lift off when I want it to shift. It’s like shifting with my right foot.

    Driving in S is bad ass. Shifts harder and faster and no noticeable issues when near or at WOT. Have yet to red line in any gear since I need to more room.

    Now for the unfortunate part.

    In Manual mode, 4th gear at around 50% throttle, 3500rpm tried to shift up into 5th, rpm jump to let's say 4000 and then clunks down and stays into 4th.
    I was able to reproduce it 3 times. On the 3rd time I did more than 50% throttle, clunked hard but stayed into 4th once again and got tranny warning about an issue and to drive as normal. Went into limp mode. Pulled over restarted the car and it went away and went back to normal.

    Thankfully this is not a use case that I'll ever find myself in since the speeds are too great and rpms too high but still unfortunate it happened.

    Unfortunately you're not the only one to experience this. Did some damage to my transmission before I sold the car.

    Proper remedy is servicing the transmission- dropping the pan, replacing the filter and replacing lost fluid from dropping the pan, then re-flashing the software again.

    Hmmm that's not great news.

    When you did the transmission service, was it just filter and fluid change ? or did they revert the software back to stock as well ?
    I did a transmission service at 119k km and now I'm sitting at 162k km. When i got it done they said doing it every 60k km is OK; but maybe it's better i do it a bit sooner given the new tune; so it's on fresh fluid

    Was the damage because of the 4th gear shenanigans and hard driving ? Or just the regular shifting.
    I've already adjusted my driving style to not be on throttle when i want it to shift; i can actually get it to shift when i want now.


    @Jake - Would you guys have a set amount of miles the car would have to be driven to get the transmission adaptation sorted or is there no additional adaptation that happens after the tune?
    Also I'm assuming if I need to reflash the same TCU tune again; there won't be any additional charges ?

    I had my Indy mechanic drop the pan, replace the filter and gasket then refill the fluid lost during the procedure - not a complete fluid flush.

    Once I got it back I reflashed the software myself, same tune as before but just re-did it to reset all of the adaptations.

    My damage didn't totally kill the transmission, but iirc a concerning amount of clutch material in the fluid for 83,000 miles. The factory service interval is 75,000.

    Not sure what longterm fix there is. It seems to be a bit different for many people, but when it happens to someone I recommend the above service and resetting the tune/adaptations.

    Basically gives it the best conditions and a fresh software for ideal operations. Seems to be one of those things where if your car was assembled on a Friday, the issue could come up.

    Latest update; it seems the adaptation has smoothed itself out.

    @Jake - if I provide the same info, email, name etc. Would I be able to re-flash the same stage TCU 1 at no extra cost if I find somebody with a JHM cable ? Or is there something else I would need from JHM ?

    Thanks in advance

    Can you clarify what you mean by this? Are you needing to reflash your own car?

    Yes, If i would like to re-flash my TCU tune(following a transmission service); with the same one how would I go about it. Can i just go to my buddy who helped me out the first time and just re-install? or does JHM have to enable something on their end ?

    Oh yes, absolutely. Just log back into your account and flash like you did before. Its already tied to your VIN

    Quick status update. I was cruising in 5th gear and I had to pass somebody and I accelerated expecting to down shift into 4th but pressed a little too hard and went into 3rd (which is fine). I continued the same throttle and shifted into 4th and tried to shift into 5th but couldn't. There was a buzzing noise and it stayed in 4th until I let off the throttle a bit and then it shifted into 5th. All this happened between 3500 and 4500rpm.

    This is similar to the previous time when this happened, there seems to be an issue with shifting from 4th to 5th under heavy throttle.

    Just FYI in normal driving conditions the transmission shifts very quickly and smoothly. It's improved quite a bit. It's just this scenario that it's behaving weird with noises.

    I wonder if it has anything to do with the level of torque in this gear at this rpm?
