Here is my current msq and a data log file I've made, no idea what this means, but hopefully someone can make some sense out of it.
Cheers.

OK, for a start it looks like you havent set your TPS bins up properly.
Looks like you are running Alpha N but have Speed-Density type entries in your VE table.
I would expect to see values of around 55 for closed throttle and 225 for WOT if you are running GSXR throttle bodies.
Connect the laptop up, turn on the ignition.
With your foot off the accelerator go to Tools>Calibrate TPS
Hit the get current button next to the closed throttle box and note the number.
Then foot to the floor and repeat for the WOT box.
Use these figures for the top and bottom rows of the VE table.
Fill in the rows in between with a range in between. Make some close together around 1/3rd throttle as this will be your cruising range.
Cheers,
David
PS I will reattach an MSQ in a min which should get you somewhere close.
PPS You are also running massively rich too.
What throttle bodies are you using?
Give me 10 mins to compile another MSQ....

Have a look at this one.
Also not sure if you need the PWM idle stuff. If not, turn it off.

David,
I've used your config file (thank you). Checked the TPS configuration and found the ADC ranges from 9 to 192, so I've adjusted the bins
accordingly (see attached).
I've also switched off PWN (I think) as I don't need it.
Still think it's not sparking right, also the AFR still show it's running way too rich.
BTW the throttle bodies are off a GPZ1100 if thats any help.
Thanks for your help.
Scott

It may be running so rich its putting the sparks out (for want of a better way of putting it). Lower your req fuel to about 10 and see what
happens.
I cant see anything obviously wrong with the MSQ file (though I may have missed something)

David,
Just wanted to confirm something. If I put the required fuel down to 10, the values in the VE table go up. I thought the VE tables values should go
down?
Cheers

Nope, they will go up.
You need to leave the VE table alone and just put the req fuel down. Do not scale the VE table.
This will have the effect of weakening the mixture across the entire rev range.
10 may be too lean anyway (halves your current req fuel). I would expect it will end up somewhere around 15.
Cheers,
David

Well here is the update for today.
I've messed around with the req fuel setting, and it did seem to improve as I lowered it (got to about 12 and it seemed happiest)
BUT still not running on all cylinders, still not seeing a consistant spark on cylinders 3 and 4.
Was think, could it be something wrong with the VB921 drivers, so I've pulled the MS out and connected it up to the stim again.
I checked the voltages on the input and output of both VB921's. The inputs are roughly the same at just under 1v, but the outputs are massively
different, one is showing 3v, the other next to nothing. Could be something to do with the stim.
Cheers
Scott

Could be a faulty coil driver.
I fited the BIP373's to mine.
If your two dodgy cylinders are on the driver that doesnt check out OK I would replace them both with the BIP's.
They are more resilient than the VB921's anyway

On the other hand I think I have the working VB921's I pulled out of mine if you just want something to try?
Cheers,
David
