I'm sorry if this is the wrong place to post, but I don't think this fits anywhere else... I have 5 original BBS basket weaves (15x7, et24) that have been refurbished and powder coated in 'smoke chrome', complete with metal centre caps and BBS centres. 4 of the wheels have Dunlop SP sport 9000 tires...

Thanks!

Andy - any chance of that info?

Cheers

Did you manage to have a look at your manuals?

Ta,

Goo (Jason)

Ok - I've sent a PM to Demlotcrew (the onlu demlot on the list, so I hope it's the right chap

)

Another quick question. The ECU (Motronic 1.3) sends an RPM signal to the Rev Counter in the e30 - I assume that this is Pin 6 - Tacho?

That's what I assumed, but getting a consensus from the experts would be nice.

Hi Chaps, I've just got one of these units second hand, and I'm planning on fitting it to Vikki, my e30 / M20B25 based kit car. www.greatoldone.co.uk Has anyone else fitted one to an e30? The physical installation looks very straightforward, but there is a software setup step that needs to be done. ...

Thanks Brian - Of course, that means yet another new intake boot, as the new one I bought a week ago from cotswold has the branch for the 'air pump'...

What exactly does this pump do? it just seems to be several concentric tubes & orings when you take it apart.

That was plan B

Hi guys, I bought a spare 325 throttle body complete with TPS for my car. My current Throttle came with the car and is the same age as the rest of the engine ('86), so it has a throttle bypass screw on the top, two outlets on the right hand side for the 'airp pump' that feeds the vac lines to the br...

Thanks all. As I have a spare three way connector from my old loom, and it's free, I'll do a switch and terminate and wrap up the other three lines in the new loom.

Bugger. My M20 is manual... Guess it time to get the soldering iron out...

I'm in the process of converting from motronic 1.0 to 1.3, and I've been busy identifying all the various plugs in the engine loom, by buzzing them out with my multimeter at the ECU connector and referring back to the wiki pages for the ECU pin out. Everything is hunky dory, except this: http://grea...

Well, there's your problem: http://greatoldone.squarespace.com/storage/idle/ECUToast1.jpg http://greatoldone.squarespace.com/storage/idle/ECUToast2.jpg Opened up both ECUs with the hope of changing the idle Transistors, only to find this horror show - same damage, both ECUs. The traces here are comp...

More research done, and it would appear that the Transistors that control the idle valve in the ECU are kaput. From what I've read, it occurs when the ICV overloads or shorts out - blowing the transistors. Which is interesting, as one of the procedures in the "Tuning Motronic" sticky calls for short...

Ok - here's the latest. Both ICVs show no life at all when connected to the loom, with either of the ECUs I have. When connected to a PP3 battery, the valve snaps open and close on both of them. Triple checking the harness back to the ECU plug still shows continuity on both of the ICV lines. Reading...

Bought a full motronic 1.3 fuelling rig from him - all looks in order (no chance to fit it yet), well packed and for a reasonable price.

Thanks!

Well, I've managed to source another ICV - hopefully that will arrive today.

I've also bit the bullet and ordered replacement gaskets and seals for all the intake side mating faces. All the hoses where replaced not so long ago, and they've been leak tested.

I will not be defeated!

Hi, I didn't touch the spring when I moved the slider arm - All the advice I'd read said to leave it well alone, as 'BAD THINGS HAPPEN' when you mess with it. My engine is an early high compression M20, but it does not have a cold start relay. It's never had a problem starting, kicks into life immed...

Hi, Can you give prices for the following please: 11121713116 x 1 - Rocker Gasket 11611717286 x 1 - FPR Vacuum Plate on Intake Plenum Gasket 11611726012 x 1 - Intake Manifold to Head Gasket 11611726010 x 4 - Intake Manifold to Head Gasket 13541289576 x 1 - Throttle to Intake Manifold Gasket 13541285...

Lower than 1000rpm - that's by ear. I don't know for certain as I can't see the rev counter whilst I'm propping the flap open. But it is stable - it's not fluctuating any more. Winding the bypass screw in the AFM in causes the revs to rise but it still fluctuates between around 1700 and 1300 when it...

Right - I believe the ICV is dead, as there is voltage at the plug, the lines have continuity - but no buzzing from the body of the valve. I left it overnight just in case giving it another shot of carb cleaner had somehow flooded the interior of the valve actuation motor. What's puzzling is that I ...

It might be even cheaper if you go to the spookily similar Eurocar Parts site and use MIDMONTH30 as the promo code.

Further update - I have sprayed the ICV with a liberal dose of carb cleaner (you could eat your dinner off it now). Whilst I had the ICV off, I noticed that the metal elbow that slots into the throttle body was very loose. As where the ones for the Servo vacuum take off. Looking at them they seem to...

Thanks for the help with the spare ECU - Delivered quickly, well packaged and all for a reasonable price.

Ta!

Update - I have tried to follow the motronic idle setting sticky, with no luck The idle bypass screw is completely shut on the throttle body, so unscrewing causes the idle rpm to rise. Likewise, I found that the bypass screw on the AFM is completely open - so much so it just spins in the socket. I h...

Received a spare 073 ECU yesterday (Thanks HairyScreech!) and plugged it in. Ignition on, measured the voltages at the ICV plug, and bugger me they're exactly the same as with my original ECU. I have continuity on the lines from the ECU to the ICV plug, so it can't be the harness, right? Or could it...

Yes - I put one up yesterday.

So, anyone got one?

I'll start looking for a replacement ECU - I don't have a source for a temp replacement, so I may as well see what I can find on eBay.

Thanks

Ok, some more diagnosis. I thought it best before I start buggering around with idle screws etc. :) According to the idle sticky, I should be getting these values from the ECU to the ICV plug in the engine bay: * between the inner pin and ground there should be battery voltage * between any outer pi...

Blue temp sensor - pin#13 and ground, should read ~300-360ohms when at operating temp, ~3000ohms when cold - CHECK TPS - closed pin#2 and ground, WOT pin#3 and ground, both should read continuity (0 ohms) when active - CHECK speed sensor - between pins #47 and #48 should read ~550ohms - Hmmm, not su...

Thanks!

No - mine is an early '86 engine, Motronic 1.0 (2 row ECU connector)

It's had so many doses of carb cleaner that I think it's now got a taste for it...

I will check at the ECU plug after work.

Resistance of ICV - measured at the ICV
Continuity on TPS - measured at the TPS

Throtte stop is adjusted as per the Bently specs - I can just slip the correct feeler guage past the butterfly valve.
