F1 Relearn

Hello Friends,

Recently took the 360 to the mechanic. We were talking about shifts and he mentioned that he can do an F1 relearn on it - he states that it would recalibrate the shifts on the F1 making it more crisp and responsive. I did a search on the forum and could not find the subject (perhaps not searching correctly) I presume this is done through computer calibration

Is this something you all have heard about, is it worth doing? Does it make a difference?

Thanks,
Coz

Pat- Ask him what he is doing, reflashing the F1 ECU/TCU or replacing it. There is also an aftermarket add-on (Formula Dynamics) for the 360 F1 system that owners have liked.

You sure he was not talking about resetting the clutch point of initial slippage (PIS) for the F1 system?

Every day I look around, and if nobody is shooting at me, it is a pretty good day.

Taz,

I think you are correct, he did mention PIS, that is probably what he meant. I guess I got thrown off when he said F1 relearn, I thought that was a computer/ ECU issue.
Anyway by resetting the clutch PIS - does that improve the shifts and make them crisper.
Just curious if this is something that is worth doing?
Thanks

Pat- On early 360s, all you can do is have the F1 TCU do an auto reset or relearn on PIS. Later TCUs also provide the capability to manually set PIS, which offers some advantages if an expert is doing it.

With the SDX you can indeed ask the F1 to do a complete self-learn operation. This procedure will engage all gears and reverse. From the different sensors the TCU can calculate the best optimized values. Maybe your shop was speaking about this?

Like Stef said there is some kind of re-learn available. My dealer did it to my car when I first bought it and the difference was like night and day, they assumed the TCU got confused at one time its history because the car was jerky when shifting, they also tried to change the PIS but in the end the put the PIS back where it was to begin with. The process took maybe a half hour plugged into the computer plus some road time with the PIS settings.

To be fair, my TCU is not the original one with the car so maybe the swap was done incorrectly or who knows what happened. My car is a 99 with a 04 TCU because according to the records the TCU "failed checksum" and it was replaced under warranty 8 years ago, no other details but the hand written failed checksum on the record.

Thanks for the input. I believe this is what the mechanic was talking about. He did say that I would notice an improvement in the shifting. It seems it might be worth doing. StefVan have you done this and have you noted a difference. Mike I appreciate the input. My car seems OK but I do not have experience, drive time or baseline to compare with.
Thanks -

Pat, no didn't do this on my car because I have a manual. But as Mike mentioned, it's worth to realign the actuators from time to time.

Unless the actuator has worn considerably, or an affected part of the f1 system is replaced (position sensors/actuator for example) then the self learn will not result in any difference to gear selection. PIS change will......

Coz,

Am having same minor gremlin on mine....

Was already taking mine into Barrett Ferrari on Wed....but this is certainly something I am also having checked and done if needed.

Noticed on mine that in 1st and 2nd Gear....she seems a little "Jumpy" I guess....especially in situations like a parking lot that requires just first gear with a little throttle.

Also noticed that after 30-45 minutes of drive time - especially in instances where there have been a few stop-and-go traffic moments, the shifting seems a little different... and it even did the "pop into neutral when upshifting from 3rd/up paddle automatically into 5th or 6th gear" issue that from what I have read is a sure sign of either a Bad Clutch or PIS Adjust.

Supposedly my clutch is fine - will verify that on wed of course - but sounds like to me a PIS adjust is needed for ours in the short term.....but budgeting for a TCU replacement for mine in the coming year.

If you have a 2004 TCU you are ok. Search on Fchat, as there are many 360 owners that have upgraded their TCU's to the newer model and or the CS TCU. The PIS needs to have a certain setting for optimum shift speed and smoothness, also helps tremendously with clutch wear. I will see what I can find.

Ok seems minimum safe is 4.2 setting, max 4.7. Have them start at 4.2, go drive it, and see if you have any forward creep of clutch drag. If so, move it up a bit. This is assuming your clutch and flywheel are in good condition.

I highly doubt you need a new TCU.

Thanks for that tidbit....anyone know what the "out of the box" Clutch thickness is - if newly installed - and what a "better change it ASAP" thickness would be??

Based on what I read on Fchat, the shop that installed my buddies CS set his clutch thickness at 100% even though it was worn 25% +. he just knew the downside that his wear reading would always be off, but he said the installation tranformed the car.
All I have to go on.

Eric- Incidentally, I mailed your TCU on Saturday. Should be there early next week, I would guess. Will make one more happy 360 owner.
