Have a MMW->TRM/Technica ECU flash?!! New release!

[ForcedFirebird]

Tell the hondata guys to make it for bmw. If it works as well as for Hondas I'll buy one.

HAHA!

This is so true. I have been writing chips for years, but OBD2 and especially CANBUS coding are far more complicated. Short of having a "black box" interface like HPTuners does for GM, there won't be a DIY plug and play anytime soon for BMW (well, you have Shark etc).

If it's so "easy" more people would be cracking the current ECU's.

Exactly.

With the brilliant amount of smart things people with Hondas are doing with hondata setups it could only get better with a pile of R3vtards involved.

With hondata you can spin your otherwise stock B16a to 9k! It's so awesome with no power shooting rods out the block.

What kind of power range can we expect from m52b28 with headers, m50 intake, with and without s cams?

This actually might be a big decision maker with going obd2.

[328ijunkie]

190-210whp. I've seen it all over with the m52. I would expect right around 200...
S52 cams add around 10whp on top of that...

[mpowerful]

Man only 10hp for s52 cams. Thats weaker than what I would expect. Hardly worth it. Anyway, Thanks for the info. Swap parts collection to continue.

Guys I got my Markert DME installed a couple days back and it has helped with some previous swap issues. The car now starts and idles at around 1500rpm smooth when cold versus the old tune where it would bog down and stumble for a few minutes and was quite undriveable until it had a bit of heat in it. After 30-45 secinds the Markert tune drops to normal idle and you're free to drive. Hot starts were not a priblem before, and they are still ok now. Performance wise I won't comment until I get it dyno'd but it feels about the same. Maybe a bit more on top but I did have the car tuned for an OBD2 manifold while running an m50 intake before. Dave has corrected that and I now have the correct map installed.

Engine is 1997 S52B32 with usual OBD2 swap items deleted. Overall pleased with the service and would recommend others to hit them up.

I do feel that my motor is not AS powerful as it should be, but it was identical with both TRM and Markert tunes so I doubt there is an issue there. I've just never felt a stock S52 to compare, under 4k it's quite lacking vs what i was expecting it to be.

Are you sure your cams are timed correctly? It's surprisingly common for them not to be, especially if you (or anybody else) has been inside it.

It is entirely possible, I'll pick a weekend and pop the valve cover off sometime soon considering how easy it is. It was apart for a vanos replacement when the engine was dropped in and I may have put them in a bit out of time. It does have plenty of pull at the top end and seems to idle fine when warm so I dismissed the possibility, but again this is my first shot at this. I did have the cam lock tool in place.

That's because in order to take full benefit of S52 cams the low compression of M52 engine 10.2:1 has to be raised. With using M50B25 pistons in M52b28 engine will make the compression be at 11.5:1 same as S54 and that M52 will make 250hp at the wheel and 275 at the flywheel, this is confirmed on a dyno.

My Subaru ej22 with one single cam head and one twin cam head for TOHC (triple over head cam) had 11.5:1 compression; with a ej20 turbo ecu mapped for the na high compression it made more than the DOHC 2500cc at 10.5:1 compression like even more than a 2.0 turbo.

It was confirmed on the kay-aei China products "dyno" to make 250awhp; up from a stock 118awhp.

but seriously, Dave and all the guys at MMW are excellent. Dave installed my m52 five years ago and its still running great as my DD. His swap parts are also in my brothers s52 e30 and neither him or myself have had a single issue or complaint about Dave or MMW. I trust his products and work over anything else on the market hands down.
