Update, I completed this swap yesterday & unfortunately it's a fail. Original mech is back in(after being up doing everything all over again until 2am). The car & DME accepted the EGS & the Alpina(and other) flash but the the shifts were EXTREMELY jolty. I tried various flashes from the sport flash, both Alpina flashes & the Euro 330i flash as a last measure.

I'm certain the issue comes in with the 6hp19zTU having much faster shifts but the internals of the 6hp19z not being built for it. The jolts were beyond the "needing to adapt" severity, so much I worried that during the short test drive if I was going to cause some serious wear & ruin the trans.

So I took my original valve body, rebuilt it with a sonax kit, replaced the solenoids, the adaptor seal, mech seal & 4 sealing gaskets & remounted it. I didn't get the Alpina flash I was hoping for, but at least I can say I've never felt my trans shift so flawlessly. Along with that I've picked up some extra low end torque, I assume due to me probably have some pressure loss due to 200K on the original trans parts.

Just wanted to update all....

oh man that sucks. probably a difference in valve bodies, clutch packs, etc that makes it shift weird - I doubt it's the strength of it or anything.

well, would you still be willing to let me borrow the mechatronic? I think the 335i still uses a PPC based computer. I have an OBD read from a 328i I think, but I'm not confident everything is there (disassembly works but it looks weird).

Absolutely, email me your address & I'll ship it out after the holidays.

I'm not too hung up on it, it was purely a boredom project & the question had been asked, I guess we now have our answer....

So I've been doing some research, and apparently the EGS also does an EWS check (and it uses a 16-byte ISN even in MSV70 cars). I wonder if that, rather than any hardware difference, is what caused the poor shifts

That's interesting, any idea what the TCU is doing with the EWS information? Could it be backup data like the mileage in the light switch?

Do you need any files or bins for this project? I've done a full download via ODB from my ZF 6HP19 and compiled a few 0da files for the same hardware.

[hassmaschine]

typically EWS just doesn't enable some function of the computer unless authorization succeeds. On the engine it disables ignition and fuel outputs, on a transmission it could be disabling something else - proper valve body control, etc. It doesn't really have any other "information", although the mileage is probably read from the CAS (or Kombi etc) and stored in the EGS.

You sure? We swapped used valvebodies with the EGS all the time? Given I always flash & recode it, but if the same ISN rules apply, winkfp & ncs shouldn't touch it if it's in there.

Speaking of swapping, why did you swap only the 335 megatronics and not the complete gearbox? Just curious. Are they not the same physical size?

Seems like it's used in EWS4 cars

Would have been much more work for experimentation considering the car is my daily driver.

Would have been a nightmare if I did the swap, they didn't play nice together & I had to swap back to get home.

You swap valve bodies or EGS modules? swapping valve bodies shouldn't trip up any modules (regarding EWS anyway), but if Terra has it right, it could be an issue with the EGS. I'm pretty sure all 335i's use EWS4, so if the EGS module was out of a 335i it would have definitely not worked correctly without EWS authorization.

GS19d.prg (which seems to be used in LCI E9x) has a couple jobs for EWS and ISN stuff. Earlier ones (gs19, gs19a, gs19b, gs19c) do not have those jobs as far as I can tell.

[dstrickland]

It was from a 2007 so it was pre lci.

Whoops, I thought LCI was in 07. I was trying to get at it being used in the MSV/D80 cars

[hassmaschine]

I guess that means MSV80 and MSD80 must support EWS3 then? Nice.

If I'm not mistaken E90 LCI hit in 09. I know I've don't cas-DME adjustments in 328I's a few times & ews4 doesn't have an adjustment procedure.

I think EWS4 was introduced with those DMEs.

[hassmaschine]

Yeah, but it appears 2007 was a transition year - so they should suport both.

That means an EWS delete has multiple vectors for attack...

[Terraphantm]

Did some investigation on my dad's E60 535:

1) The EGS supports EWS, but apparently not used. I do see references to the E70 X5 with the same EGS having EWS. So I guess BMW built a factory EWS delete for the GS19d in pre-E70 models?



2) MSD80 on this car is EWS4, and it says it doesn't support EWS3. However, simply by virtue of there being a field that says "EWS3 Capable", I'm willing to bet there's a configuration byte that can enable EWS3 mode.

[hassmaschine]

I don't think any E60s were EWS4 - so that makes sense, assuming the only version the EGS supported is EWS4.

This E60 definitely seems to be EWS4 based on the DME output posted above.

Er, duh. lol
