My M30 conversion

Sun Jul 17, 2011 10:10 pm

I did swap it for the other one I had which didn't make any difference, I have since found another however on my old M20 loom that I could try.

Have you taken them out and bridged them to see if it runs?

Sun Jul 17, 2011 10:17 pm

Bridge the DME relay? I have bridged the fuel pump relay and that gave me power to the fuel pump. Tried 3 different fuel pump relays and neither of them would get power to the fuel pump

Sun Jul 17, 2011 11:06 pm

bridging the dme relay will permenantly feed the ecu and if it worked it would mean you have no ignition feed from the ignition switch to activate it.

Sun Jul 17, 2011 11:14 pm

Do you have 12 volts at the coil with the ignition on?

Sun Jul 17, 2011 11:22 pm

Yes I do. I started a thread in Technical Help earlier, daimlerman kindly gave me a few pointers on what to test http://www.e30zone.net/modules.php?name ... c&t=202151.

I'll try the other DME relay I found and check if I have a feed to the relay with the ignition on tomorrow after work

Mon Jul 18, 2011 6:43 pm

I have a permanent live feed to the DME relay, and both 87 pins become live when ignition is switched on.

EDIT - I have a spark. I have changed the fuel pump and DME relays. Still no power to the fuel pump when cranking, but definitely has a good spark

I'm borrowing another ECU tomorrow to see if that does the trick, hopefully it will start then!

Sat Jul 23, 2011 9:10 pm

It started at last!

Tried another ECU and it fired up! (Thanks Tom

) Idles a bit rough at the moment but a few of the vacuum hoses look a bit suspect so I'll sort them. Had to put the centre section of exhaust on to quieten it down a little as my elderly neighbour is ill at the moment and didn't want to scare the crap out of her! But it still sounds like a beast

Oil light went out fine, everything works that I've tried so far. To say I'm happy is an understatement, I can't wait to take it out for the first drive, going to tax it start of August.

First trackday will be end of August

Sweet, well done mate.

Mon Jul 25, 2011 4:31 pm

Very good to hear fella. Well done.

Mon Jul 25, 2011 6:40 pm

Thanks

Got a few more bits to finish off, fit the exhaust properly, put a front wing back on, bleed the clutch etc. But I'm very relieved it runs!

Mon Jul 25, 2011 7:38 pm

Have you got the itch to drive it then now?

Mon Jul 25, 2011 9:01 pm

Good one, nearly there now

Mon Jul 25, 2011 9:06 pm

Glad the ECU fixed it mate

All the hard work is over now, bar the soldering iron !

Mon Jul 25, 2011 9:31 pm

Yep, thanks again Tom

I'll bring the car round when it's back on the road so you can take it for a spin and see what you think!

Tue Aug 02, 2011 11:48 pm

Is this done yet?

Wed Aug 03, 2011 9:53 pm

Not yet Lee, flat out with work again, managing to get half-hours here and there to work on it. Am hoping Sunday will be free so I can finish it!

All thats left to do is replace the couple of leaking crush washers on the PAS pipes, bleed the clutch system, finish soldering the c101 plug wiring, and just tidy up the wiring. So not much at all really. Tax being bought on Saturday morning

Wed Aug 03, 2011 10:04 pm

You have come a long way since I last checked in.
Soldering the C101 wires is about a 20min job, so chop chop.

Wed Aug 03, 2011 10:06 pm

lol

Believe me mate, I really want to finish it asap, so close now!

Fri Aug 05, 2011 10:22 pm

Chop chop, i want brown pants!

Sat Aug 06, 2011 10:08 am

Won't be long Matt, looking forward to the first blast over the Mendips!

Sun Aug 07, 2011 7:09 pm

Got a new soldering iron from Maplin yesterday, soldering was going well until the last wire when the crappy thing stopped working! So couldn't finish the soldering, and the car has a big puddle underneath it cos of this shite weather so couldn't do anything under the car! So not a very productive afternoon

Tue Aug 16, 2011 8:02 pm

Got a couple of days off work, so finished putting the car back together today, just need to make up a couple of brackets to hold the air filter housing and washer bottle in place. Taxing the car in the morning as long as a small test drive goes ok first, if everything is ok I'll be taking it upto Retro Rides gathering on Sunday

She's not well at the moment

Idle is hunting from 1500 down to nearly stalling, and doesn't rev very cleanly, almost like its missing slighly. I've had a good look around the vacuum pipes and ICV pipe, and I have found a couple of small splits, hopefully this is the cause. I also have new plugs and leads to try, and I'll clean out the ICV. Hope it's not the dizzy cap and rotor arm as they are fookin expensive!

You and me both mate

iirc my dizzy and rotor was around £50 from GSF, both Bremi items too.
ECP wanted 70 odd.

Sat Aug 20, 2011 12:50 am

I've been following your thread mate, must be very frustrating! I've only looked at ECP for prices of dizzy cap so far, my Dad has an account with GSF so might just get all new bits and then its done, not planning on getting rid of my e30 for a while so worth the investment I think!

Sat Aug 20, 2011 12:59 am

Oh, and the heater blower fan doesn't work, everything else does though so I'm going to have to take another look at the c101 wiring I think as this can be an issue on m30 swaps from what I have read!

Sat Aug 20, 2011 10:03 am

There's only 3 wires to cut and reconnect on the C101, so maybe one might be wrong

I

Sat Aug 20, 2011 10:26 am

I had to completely re-do mine Rav, as I have the later engine and loom!

Sat Aug 20, 2011 11:12 am

What loom are you using??
E34??

Sat Aug 20, 2011 11:52 am

He's using a late loom with a different plug Rav.

What about interior lights and windows?

You need to dig the green wire (pin 15) out of the body side of the c101 and earth it.

Sat Aug 20, 2011 2:23 pm

I remember now.

Interior lights and windows perfect! So hopefully its something silly like the fan stuck where I've taken so long to do the conversion...
