Really need some help!!
Turbo Mini Forums

My original plan was to use the original MEMs ECM to run the Eaton M45 - but as was pointed out on this very site - it didn't happen.

So - I've raided the piggy-bank and bought a Vmax MPI 150 kit and fitted it myself (really couldn't make the journey to have Stuart do the fitting and I like to get my hands dirty).

Anyway, got everything fitted but I'm having real problems getting the Mini running.

Keep getting really, really bad misfire.

I've been scratching my head for a good few days - the Mrs is getting really pissed off with the Mini being grounded, but I'm still no further forward with getting on the road.

Anyone got any advice as to where I should be looking?

"se ne estas rompita, ne ripar ĝi - supercharge ĝi."

Ignition timing??

when is it mis firing? could be fuel.

I run a supercharger and I don't care the TB is on the wrong side.
VEMS + 12 PSI + Liquid Intercooler = Small Bore FUN!

ht leads on correctly?

"se ne estas rompita, ne ripar ĝi - supercharge ĝi."

Is anyone else running the Emerald ECM?

Any chance you could email me a base map?

"se ne estas rompita, ne ripar ĝi - supercharge ĝi."

Just give stuart a ring, im sure he will give you some advice

usually any missfires under boost are caused by a lean mixture ..... if all other avenues have been checked,

have you a wide band lambda gauge fitted ?

if not i would have a rolling road session to sort this out PRONTO!
if only to save your pistons and espcially to releive the ear Ach for the missus .....lol

could you not stick a dizzy on it temp to eliminate emerald from the equation?

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

If you are using Wasted Spark coilpack with your ECU, it's worth fitting a 20 microfarad capacitor off a Ford coilpack to prevent misfiring.

Certainly sorted mine out on the van.

Lots of info on fitting the capacitor at:

Good luck

Minivanless, but reluctantly happy living with the decision. There'll be another one day.

post up a screen shot of your fuel and ignition maps.

Have you calibrated the crank position sensor with a timing light?

Ok, had another attempt at getting the Mini running and I can't even get it started. I'm starting to get seriously pissed off with this - but I know it will be worthwhile once up and running.

As requested here are the ignition and injection maps

So, going over the basics - got the spark plug gap set at 28 thou; valve clearance at 12 & 15 thou (inlet and exhaust).

Any suggestions?

"se ne estas rompita, ne ripar ĝi - supercharge ĝi."

Right, I've said bollocks to studying for my Project Management exam next week for the time being and spent yesterday and today going over my install.

Don't think the head gaskets have blown (I know it's a bodge using a decompression plate, but had to stick within the budget) - couldn't find my compression tester - I'll get a new one over the weekend.

Cleaned and re-re-gapped the plugs.

Rechecked HT connected to Coil pack and that it actually produces spark (which it does).

Turned engine over a couple of time with fuel pump disabled, and what do you know - she started up.

Making progress.

Tried to smooth out the idle, still getting the occasional miss. Took her out for a run and seems to be ok under load - not happy when coasting to idle or when stopped.

Not sure what the problem was before.

Any suggestions on how to get a smoother idle?

Noticed that the crosshair on the live adjustment screen never sits in the yellow on the target and the lambda jumps about a fair bit.

"se ne estas rompita, ne ripar ĝi - supercharge ĝi."

the idle advance area looks quite bumpy,

I'd set every thing in that area to about 20 deg so start with and see if its ,more stable

Cheers mini13 - I'll give that a try.

Just when I thought everything was starting to go my way.....
:(
One on the bloody headgaskets has gone - luckily my local motorfactors had two Payen AF460 in stock.

Gonna spend tomorrow getting it sorted.

"se ne estas rompita, ne ripar ĝi - supercharge ĝi."

DOH!!

well, thats one reason that we dont like decomp plates :?

mind you, that said I ran two gaskets stacked for a couple of thousand miles with no troubles, could be that you had a dodgey BK from the bad batch....

check the new ones out before you bung them on just in case

Aye - soooo gonna get the head pocketed, but still skint and student loan and my wages are just paying household bills..... :( So it's gonna take a while.

Any tips on fitting the budget version of a MLS gasket?

The first time I put the gasket/plate combo in place before the studs - seemed the best way to ensure no damage to the gaskets.

Anybe I screwed up and there was damage - I find out tomrrow.

I'm fucking gutted. Wife ain't talking to me....

"se ne estas rompita, ne ripar ĝi - supercharge ĝi."

If the two graphs are the same orientation one shows throttle rising from the bottom left while the other shows throttle falling towards the bottom left. That in itself is a problem?

I agree with Joe about the lumpy map at idle. I'd also have a look at smoothing the rest of the ignition map aswell tbh.

What lambda reading are you getting at idle?

1/4mile in 13.2sec @ 111 terminal on 15psi

Thats the big problem Matty, we don't know as there is no lambda gauge or sensor

I have a wideband lambda sensor fitted - TechEdge 2J1 - I'm just using the display in Emerald in the mean time.

At idle I'm getting a reading of 11.

The maps I'm using are the ones supplied from Stuart, he said they shouldn't need much alteration.

"se ne estas rompita, ne ripar ĝi - supercharge ĝi."

11 is about right at first start up. once warm you should be seeing roughly stoich (14.7)

if your fuel pressure it too high it could be making it rich across the board.
