Guys, I seriously think all these hiccups are the car's ECU adapting to the new map.

cn555ic, did you disconnect the battery for an hour before or after installing V2.0.02 12/19map?

I installed it yesterday and have almost 50 miles on the stock map settings and it's been rock solid and smooth since I fired it up and started testing yesterday. No issues and I left the battery disconnected for an hour or so before starting the engine. I then warmed up the engine with some mild pulls to 3K, 4K and 5K RPM. Then once I was up to 230 degrees or so, I started the 2000rpm-redline pulls from second. The car is just amazing. With all the police on the roads because of the holiday drivers out there, it's difficult to get enough open road in town to do any meaningful testing without attracting a lot of negative attention. But DAMN the car is seriously fast now.

If I was having any kind of hiccup or strange engine behavior obviously caused by some ignition or fuel delivery issue, my first action would be to reset the car's ECU and at least eliminate adaptation as the problem.

Just to check, does disconnecting the battery also reset the step on AT cars?

Good question. I can't comment on whether disconnecting the battery affects the transmission. It affects other systems in the car so it would make sense that it would reset parameters related to the Step also.

Maybe Eugen can comment...

Cool. I tried resetting it for my tranny with that 25sec ignition on trick where u kickdown for 25secs in ignition on mode. It seemed to have worked. Though i dont use DS often, sometime when i am driving it, it seems that the gears are all messed up in DS. D and Manual mode is completely fine. I have NEVER disconnected my battery but i have yet to have any problems so far as a result of that. 2.0.2 is a very good map but i feel that the car can do more for low/mid range torque. It just feels mundane at that power band.

I hope 2.0.3 can be the king map. Absolutely what we ever wanted. I loved 2.0.1 for its stability. 2.0.2 has only been in my car for 2 days now so i cant comment though redlining it is like a F16 fighter with afterburners.

Wish Shiv the best for 2.0.3 map!

I don't know whether the AT transmission learns from scratch as well after disconnecting the battery, for me it seems to be like it does.

Yes the tranny learns as well from scretch.

Same thing here. V2.02 12-19. One year old sedan AT. Happened while the car was warming up headed home from work, oil temp just coming off peg. Same gas from the same Shell station I've used for a year. Small amount of throttle from a stop and engine felt as if it died for a quarter of a second. Did it again 30 seconds later. Started the car next morning and could not duplicate it. I am not having any of the fuel pump symptons though that was my first panicked thought. The car had been driven about 50 miles since loading V2 but I had not disconnected the battery cable per Shiv saying it wasn't necessary. I had done third gear pulls up to 5k but not higher. Too much Christmas traffic at the moment. I will play some more when I get back from vacation.

Exactly what i experienced too. I couldnt replicate it. Most people say you get that when u step off the throttle too fast on 3rd and 4th gear when you are in thee high rpm band. Ever since my first time i got it, i tried it many times but could not replicate it. I noticed it happened when the engine is relatively cold.

[cn555ic]

it happened only from the initial upload of the firmware and new map...Its has since gone away since over 90 miles...No more symptoms of the jerk from stop at all...It seems to work perfect now...I am guessing with the with the new firmware and map it had to adjust somewhat...Has anyone with this buck from a stop continued to have this buck from a stop?? Or was it from the initial upload of firm and map 12-19

[Tuned335i]

Adaptation...adaptation...adaptation...it will go away in time...be patient grasshoppa...you will reap the rewards of the PROcede V2...

Seriously, the stock ECU is adapting to some seriously revised engine parameters. Give it a break and some time to adjust and you'll be rewarded. Of course this is easy for me to say cause i disconnected the battery and gave it a head start in the adaptation phase!!!

[SGP335i]

This map is a beast.... I'm set at 94% and peaking at 15.1 lbs and it is much faster then the 1.47 and no problems.... Thanks Shiv

[Tuned335i]

+1 Hehehehehehe!!!

Christmas eve and I'd love to bump my settings up and see what happens. Have to wait till I'm sober tomorrow... Gotta get my boost gauge installed tomorrow too

My default V2.0.2 12/19map settings are peaking at around 13psi and I'm running about 95 octane mix. Looking forward to some 2nd-4th gear pulls to redline at incrementally higher torque settings till I get there!!

[M3EST]

I drove the new v2 6mt map 12/19 for more than 50 miles and i feel the same hickups when cruising at stable speeds between 2,500 and 3,500 rpm in all gears.That was not existing in stock or in 1.47.Feeling that i miss the perfect 1.47.Maybe the return of the solenoid back to stock causes all this issues.

[cn555ic]

just drive it and it will hopefully adapt itself...My car had the hiccups twice and since its never happened again...Already clocked 140 miles on new firm and map and no more issues so far...I love this map for some reason it makes it an animal, better than V1.47...

[Panoz]

I have the feeling that the Hickups starts fading as the car adapts. I guess that the car needs to be driven quite a long in order to experience the true potential of the new map.

I would have to agree to this because thats what happened to me and after 180 miles with V2.02 12-19 its just been soooo smooth!!!! I love it and want to drive just to drive!

[e.n335]

The new way of boost control is a good thing but I think we will see further improvements on this boost control.

In the meantime it works for me to let the ECU adapt from scratch ( disconnecting the battery ) after every map or user defined torque settings change. Further v2.0.2 has been developed using a new 335i progman release. I will upgrade progman by end of Jan. 2008, at this time v2.0.3 will be out.

Being somehow careful now and upgrading the PROcede map and car software by end of Jan. is my way to go. PROcede V1 needed a couple of releases until the final v1.47 got rock solid.

I agree. I have not had any issues or unexplained hesitation/hiccup when updating firmware or maps and I use the battery disconnect step. If it was a pain in the ass to disconnect the battery I could understand skipping it, but it takes less time to disconnect the battery than to type this sentence...

[M3EST]

we will see.Lets wait some more miles.
