Hi. I've got the wasted spark conversion from msd. I got them to fit the driver to my super 8 ecu running 8 injectors but i haven't had the car running properly since. I sent it back to them to get checked and when i got it back it only ran on cylinders 2 and 4 a few times but won't start at all now. I've fitted a new amp as i thought it could be that but made no difference. I took the spark plugs out and they all spark initially when i turn the ignition on but when i turn the engine over only cylinders 2 and 4 spark. Any help would be appreciated as i'm tearing my hair out lol

Thanks

Was it running fine before going for wasted spark?

studabear

have you got the plug leads correctly on the coil pack? reason I ask is because the wasted spark fires 1&4 and 2&3 together, so either your coil pack is fooked or you have the ht leads on the coil wrong and one half of the coil is not firing?

Lee1419

It had a slight misfire before that got worse that's why I got the wasted spark but it turned out to be the cylinder head was cracked. Just had the engine fully rebuilt and bench dyno'd so I know it's something electrical. It was run in on distributor and diff ecu tho.

Lee1419

Yeah the leads are on as per instructions which I think was 4-3
1-2
I did think it's maybe my luck that a new coil pack is faulty but then I'm thinking it still could be the ecu not telling it to fire?

That's wrong, you essentially now have two coils. These should have leads 1+4 on one, then on the other should be 2+3.

This gives the coil more time to charge than using a single coil plus other benefits I wont go into here now.

Lee1419

The coil pack is square with 1 below 4 and 2 below 3 as per instructions.

markk

iTrader: (2)

Correct, just make sure you have the pairing correct.

Lee1419

Yeah all is in the correct order. Can they be swapped to check if one side of the coil pack is faulty or need to be in that specific order?

markk

iTrader: (2)

Yes, but the ecu will still try and fire the corresponding cylinder, swap the pins over and you can use any side of the coil you want

Have had this problem since fitting wasted spark for 4 months now! Still trying to sort it after new coilpack, new amps, another leads to amps, loads of different plugs, tried another ecu too. Il be going back to group a coil.

Lee1419

Swapped the wires over and cylinders 1 & 4 are firing now so coil pack is working. ECU fault it seems to be then. Back to Motorsport developments for the 3rd time. Had the ECU checked on another car running msd wasted spark and it's popping and cutting out and won't start again the same symptoms i'm getting.

Lee1419

That's not confidence inspiring lol. Yeah I've had the issue for months also

Have you spoke to msd ?

Lee1419

No not since the 2nd time they had the ECU. Gonna phone in the morning once they open and see if they will check it again.

Mines been faultless since fitted6 yrs ago

timster

Fitted mine Christmas time, works great!

Gadget

Had the same problem, had it all fitted then had all sorts of problems.
Ecu was fine before, then after, ecu buggered!

I keep reading about W/S ECU's tested???? I may be wrong but since when did MSD start servicing and testing ECU's - i was under the impression that James tests the ECU on a like for like car not the actual ECU as i had mine checked in the early days, i had the driver fitted in 2009 and had to wait for a L8 W/S car just to plug in and see if it would operate but mine turned out to be the baby board ribbon had failed.

So if James has said it operated fine then you need to start looking elsewhere on the car

Lee1419

As i mentioned in an earlier post the ecu was checked on another car running wasted spark and won't run it.

Jay,

iTrader: (4)

I think really if you havnt got miss fires then dont fit it BUT if you need it go to msd and get them to fit it

Lee1419

I def don't have any misfires cos the car won't start lol. I got the kit because I developed a misfire but turned out to be a cracked cylinder head.

BRAMMER

iTrader: (23)

Right so if the board is fitted right then the ECU must have a little issue somewhere

If i were MSD i would sell the kit with the driver board fitted by them

Lee1419

The driver board was fitted by MSD. I wouldn't attempt opening the ECU up myself. Yeah the ECU seems to have an issue but it was functioning fine before I decided to go for the wasted spark. That's what's frustrating.

luke19790_3

And did the ecu off the other car run fine in your car?

Mr RS500

iTrader: (6)

Well if thats true im quite disgusted , I wouldnt be happy if my car was at MSD and they were plugging in other ECUs into my car that could have faults

Not exactly what you would expect , your car being used as a test bed for faulty parts

Shocking ,

Jay,

iTrader: (4)

With the car them ino

They have for a while iirc plus if there selling a product that changes the way the ecu works then why shouldnt they

BRAMMER

iTrader: (23)

Don't quote that as absolute correct Paul i'm just assuming they may have another way to test

Mr RS500

iTrader: (6)

Im sure they have mate , as i cant see them plugging possible faulty ECUs into customers cars

gray_rs

My rev counter isn't right on my escort since fitting a few weeks bk?

BRAMMER

iTrader: (23)

Sure you have to alter something

timster

Paul
For the record when James fitted my wasted spark driver he tested my ecu on his OWN car

Mr RS500

iTrader: (6)

so they do test by plugging them into another car then

timster

Oh dear, is someone looking to shit stir?

Mr RS500

iTrader: (6)

Lol, If i wanted to shit stir i would , I just make a comment that ,,IMO ,, testing possible faulty ecus by plugging them into other customers cars isnt what ,,I ,, would be happy with if it was my car being used as a test bed

all MY OPINION ,,

can you smell it too :cry

Mr RS500

iTrader: (6)

Lol,

the MSD fan club are out in force

Paul you are clearly jumping to conclusions without facts though mate. You confirmed it in your own head because someones ecu was tested in James's car. James isn't a customer so why are you worried about ecu's being tested in customers cars?

Why doesnt someone actually speak to MSD??

They are a grown up company and should offer you a suitable level of customer service.

In my experience, stu takes pride in making sure his customers are treated properly so best give them a bell.

Why do most people defend MSD on here? Have these people defending them ever used them?
My personal experience of MSD was not good. I won't go into specifics but suffice to say I spent a tidy sum with them and was not happy at the results. Before anyone asks no I didn't contact them about the problems because they would not give any kind of warranty as it was a rally car.
