I think I mentioned I had 173's too, what are they from??

Got plenty of the 150's then.

Post Wed Oct 12, 2011 10:22 pm

173 is the facelift 325i Motronic 1.3 ECU - one of the best out of the bunch.

The 150 was Motronic 1.1 fitted to early M30B35s, while the later ones had the 179 Motronic 1.3 ECU - the same as a 173 apart from the EPROM chip.

What is the difference between 1.1 and 1.3?

Post Wed Oct 12, 2011 11:03 pm

1.3 has higher resolution than 1.1 (more memory map locations), thus giving enhancements in driveability, and slight power gain.

Also, it was designed for running catalytic converters on later models.

The main advantage is it has just one PCB, making it more reliable and easier to chip.

Hi

Saw these on ebay and thought of your thread...

http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... ink:top:en

how easy would they be to fit i wonder??

jim

Post Sun Oct 16, 2011 3:36 pm

Cant remember if they bolt straight on but im sure they need a plate making up to fit, Rav will know.

Post Sun Oct 16, 2011 4:57 pm

Jim,
You'll need an adaptor plate to fit those, available from Germany.
Also the thermostat housing will need altering, basically cutting and welding the top outlet to a different angle.
Also, those are well overpriced!

Post Sun Oct 16, 2011 5:13 pm

How much is the adaptor plate?

Post Sun Oct 16, 2011 5:31 pm

they do look good but not sure if you would get any real extra BHP though, maybe 20 or so max.

wonder how much a port, polish, 291/283 cam, 1mm oversize valve and seats would and decent free flow exhaust would add in BHP and Torques terms??

BTW....I had to look after the children this afternoon, so set them up with lego and read the whole thread....brilliant read, really nice way to spend an hour or so on a sunday afternoon with the radio on. I've got a nice M30 donk so just doing "research" and collecting bits ready for an installation next spring into the e30 cab, need to source an LSD also as currently have 4.1 open = new tyres every traffic lights. lol

What do you do about the plenium (sp) and AFM? is there a thread anywhere with pics etc...

Jimbo, Lego FTW

Post Sun Oct 16, 2011 6:28 pm

Take a look at Staleyturbos thread, he's running these on his M30 set up with plenium.

Post Sun Oct 16, 2011 7:29 pm

These need quite alot of work to make fit but there mega

I had a look earlier

how much power can you expect to gain with these?

Post Sun Oct 16, 2011 9:54 pm

Coupled with a cam and six branch, prob a good 30-40 hp. Its ok saying they will fit, but I've never seen these used with standard management, I'm not sure how that would cope?

Rav?

Post Mon Oct 17, 2011 2:19 pm

I've been told that the itb's will run on standard management, so we'll see when I do mine.

Post Mon Oct 17, 2011 2:56 pm

this has some useful info on:

http://www.m535i.org/officers/ra/article.html

ITB bit pasted below:

There are two options for a individual throttle body system. The first is to attempt to retrofit the M5 intake system. This requires at a minimum fabricating adapters from the head to the M5 intake runners. It also requires investigating the choice of fuel rail, as the M88 or S38 rail and FPR will not clear the t-stat housing on the M30. Similarly, the TPS switch will have to clear the t-stat housing. To do this the adapters have to be angled so as to point the intake runners above/below the t-stat housing and rad hose. The other option is to get the Weber DCOE adapter brackets from Redline Weber (Redline Weber part # 99004 094). The castings aren’t that great, so porting and polishing them is a must. However, 40mm or 45mm Weber fuel injection ITBs can then be bolted onto these. Again, one of the flanges near the t-stat housing has to be shaved a bit to clear, and I have not verified if the TPS switch will clear the t-stat housing and rad hose, but this looks to be more a ”˜bolt-in’ solution. Additionally you’ll need a custom intake plenum. http://www.jameng.com and http://www.twminduction.com are both good sources for the ITB components, as well as Top End Performance can order anything from Redline Weber.

I've seen this before, it's a good read. I would definatly be thinking some better engine management to get the best out of the m30 though, removing the dizzy aswell. I'll be taking alot of this into account when building my next lump and head.
I have a spare oil cooler if you need one?

Post Tue Oct 18, 2011 12:19 pm

is the oil cooler a simple (ish) fit to the M30? Am interested in it

Post Tue Oct 18, 2011 12:30 pm

Its off the euro 535i so its a straight fit. In excelent con. Give me a pm if your interested.

Post Sat Oct 22, 2011 12:43 pm

Ive got an M30 oil cooler housing somewhere, it came on the B10 but didnt have the pipes or cooler but ive heard M20 ones can be used.

Update later ive got another ECU to try (thanks Jake), fingers crossed!

Post Sat Oct 22, 2011 1:24 pm

ECU is on and let it tick over for 10 minutes, so far so good! ill take it out later to see whats what.

Is there a procedure to take when i do the half hour drive to re-learn the settings?

Post Sat Oct 22, 2011 2:47 pm

What ECU you trying now?
And were the 2 I sent you no good at all then?

Post Sat Oct 22, 2011 3:05 pm

Ive got a 173 now with my pina chip in.

The two you sent the one wouldnt run and the 150 was an early twin board business.

Post Sat Oct 22, 2011 3:18 pm

Okey dokey, btw, i'll be needing those mounts week after next.

Post Sat Oct 22, 2011 3:21 pm

Post Sat Oct 22, 2011 3:58 pm

Just drive it in all gears using all the rev range, which should transfer across all the settings.

Sometimes, it can take several drives or a few days to fully bed in.

Post Sun Oct 23, 2011 9:42 pm

Well ive been using it with the new ECU and everything seems fine, spluttering has gone and it pulls smoothly. Still doesnt feel like a 260hp lump though so its getting booked up next week to get it on the rollers and see whats what.

Anyway, some may remember these.

Staggered Exips 7j & 9j

They now look like this....

Check the 3.5" Dish

Ignore the Champiro's there just my ebay bargain test tyres.

Well with them done and the car mobile again i couldnt resist trying them on before they get served up.

Proper council ay they.

Post Sun Oct 23, 2011 11:51 pm

They look quite smart to me. Good to hear you've got it running smoothly again.

What number was the ECU that gave gyp?

Post Mon Oct 24, 2011 10:52 am

Belive it was his 179.

glad to hear it's running correctly now mate.

Post Mon Oct 24, 2011 8:23 pm

Yep it was a 179.

Post Mon Oct 24, 2011 10:15 pm

Strange - they're identical to a 173, and these are usually pretty reliable.
