Stripped all the insulation tape on the ECU harness today to check everything is wired correctly, which it is. I then made sure the the two ground wires where not bunched with any other wires and ran them separately to the ground point in the engine bay, then also ran a wire from the ground point to the battery negative.

Still have the miss fire/hesitation at 2800rpm.

There is only one other Pelican I know of that also has a Microsquirt ECU (also on an SC turbo conversion) and he has the exact same issue! His setup is more advanced than mine with spark control too (mine is very minimal, just fuel).

This doesn't seen to be a problem that you guys with Megasquirt have so is it maybe something to do with the Microsquirt ECU!

I have maybe gone as far as I can go myself. I just don't know what to check or do next

It maybe just easier for me to remove the Microsquirt ECU and install a Megasquirt v3

In your datalog does it show injector pulse width dropping at the same time your RPM's are dropping out? Are there any synch loss issues at the time? If there are no pulse width issues or synch loss issues then I would think it is an ignition issue.

Edit: I not sure how you are inputting RPM's into MicroSquirt. If you not using a trigger wheel then synch loss would not be applicable. I assume you are running MS2 Extra software. You may want to post on the MSExtra forums for some more help.

Thanks dap930,

I will take the car out this weekend and get a datalog and post it here first, see if anyone can throw some light on the issue.
For the RPM feed I tapped into the wire that the MSD ignition use's to read RPM. It's from the connector block that used to plug into the OE ignition box. It seems to work fine but I guess could be a issue for some reason.
Microsquirt has the latest Firmware (MS2 Extra) and I use TunerStudio, again latest version.

I have to agree with everyone else. That is a cool looking slant. It's one of the few I've seen that actually looks like a race car.

Thanks guys

Fitted intercooler version 3 today, pics to follow

But back to the miss fire issue.

The weather here is now a lot colder than last time I ran the car and the tune was was out, too rich, guess that's another thing I'll have to look into.
Anyway, I let the autotune do its thing for a while and after made a logged run.

You should be able to download the log here :
TinyUpload.com - best file hosting solution, with no limits, totaly free

I have made three red line markers on the log but the last one shows the issue best.
You can clearly see the duty cycle drops at 2800rpm.
So what could cause that?

Also I notice my injector duty cycle is showing well over 100 in places.
I'm using ACC-150136 injectors which are 36lbs.

I posted on the MSextra.com forum with my log and instantly got some replies.
A few guys picked up some of the sensor readings where strange but this was due to those sensors not currently installed on my motor (I've only got 3 or 4, very simple setup so far).
One of these was the TPS, when I said it wasn't installed yet they said I should ground the signal wire to the sensor ground otherwise it will be acting like an antenna and picking up interference.

So that's my next job at the weekend.

If your injector duty cycle is over 100% the injectors are too small. You probably need at least 44lb/hr or more. I am running 55lb/hr injectors and I am hitting 94 - 96% DC on my car, also a 3.0 liter, but running higher boost.

You should consider installing a TPS sensor, it can help with accel enrichment.

If your AFR's are changing from warm days to cold days, your MAT correction curve needs some attention.

I have not looked at your datalog yet, will try later.

Thanks.

Plan is to fix the rpm hesitation issue first, then order probably 55lb injectors and install TPS and boost solenoid (both are sitting here ready).
All the other little issues are just TunerStudio settings so I may get it to a tuner after the above and get the settings all done correctly.

Grounded the TPS signal wire ok.

Now in the log the TPS signal is always at 0.0%, but it hasn't fixed the problem

I was finally able to fix my hesitation. My spark table was not advanced as much as it needed to be. Absolutely no hesitation now. Have you thought about just going distributorless? you can do this on the cheap. I think i had a total of about $75 in used ford EDIS module, coils, and plug wires from a Ford Crown Victoria. The most expensive thing is the crank pulley. I used the goingsuperfast pulley and VR sensor clamp.(looks to be under $250 off ebay.

Thanks for the update, glad you've got your sorted now

Distributorless is on the to do list but it was a bit further down the road.

I know I probably have my MSD boost retard set a bit conservatively so I may look at checking that.

Otherwise I may just go TPS, Boost solenoid and Distributorless all in one go and see what happens

OK time for a new shopping list for ignition control :

This time round I will be aiming to fit the Carrera 3.2 intake I have also.

1 x Distributor Bock Off
1 x Crank Pulley
1 x Crank Trigger Sensor Mount
1 x Crank Trigger Seneor
1 x Trigger Wheel 36-1 For Megasquirt
1 x Ignition Coil Pack

I will get some of the bits from goingsuperfast as they do a kit which takes care of the dizzy block off, crank pulley, crank sensor mount and trigger wheel, so nice and simple there.
They also sell a coil pack and trigger sensor :

Ignition coil pack Chrysler V-6 DOHC 3.6L or 3.8 L. Niehoff patrs AL173 $90
Crank position sensor 2004 Ford Focus 2.0 DOHC 948F 6C315 AA $45

Maybe easier to just get the lot from one place.

Anyone know if these work with Megasquirt?
And also would I be able to use my existing Magnacor plug wires?

Are they any other parts I would need?



Or alternatively I go EDIS 6.

I think for that I need 1 x Ignition Coil Pack and 1 x Ignition Module

Is that correct?

I know you're pretty handy with mods, Gavin and probably don't need any help, but just in case you need any notes:

3.2 Carrera manifold on an SC

I believe you need the EDIS 6 ignition module with the Chrysler coil pack also.

I found my 80lb injectors on eBay here in the US for only $300 new.

There were quite a few selling around those costs.
