Just Got my microsquirt running! badly

Post by dave36 »

2017-05-14_12.10.49.msl
microsquirt using msextra firmware on ford zetec silvertop 2.0 zetec
Actually got my first start today, fault was broken wire from pin31, hence no rpm in tunerstudio! I have yet to add the MAF and intake temp sender - I have attached my log - multiple restarts as no tickover as yet! any advice and instructions to change settings welcome.
cant find settings in tuner studio, they are: Cranking trigger -calculated, trigger wheel teeth = 0 and set predictor algorithm to last interval.
thanks for any help or files offered

Is there a specific reason that you are running an obsolete beta firmware?

I'd strongly suggest that you upgrade to the current release firmware from the Downloads page.

not a clue, the microsquirt is as supplied to me, with a base map for the Zetec. I did not know there is a need to upgrade, I will have to have a look and see if I am up to the challenge!

Best to ask your supplier first.

thanks James, I looked there and am fairly confident I can do it, though my supplier has told me if I update firmware his support will end!
Map - still not sure what settings I should input, it is 20 - 250 kpa rated
MAF is still on the bench, IAT still not fitted, engine fires up straight away on the key, but dies as soon as I touch the pedal!

With no MAF and no IAT, it really can't fuel the engine properly, so not sure what you're expecting from it?

thanks for that, I do have MAF but its not connected as I have MAP which is bosch 0281002119, values I have are 20-250 kpa and mV396-4610, no idea how to translate those into values the tunerstudio will accept, as tuner studio seems to want the values entered as %.
I have MAF but I have been told that its not needed, IAT is present but not connected as yet, engine fires up no problem, idles until I touch the throttle, then dies.
Trigger wheels, my supplier, tell me I don't need MAF if I have Map and that support will end if I upgrade firmware, so I am a little lost on how to proceed!

you do not need the maf as well as the map sensor. the calibration is input at under calibrate map/baro it will be a kpa value at 0v and the kpa at 5v you need to enter. post the tune file off the ecu and a bit of info on you zetec engine is its going to have a turbo or getting itb's ect.

the newer firmware's do have various bug fixes, the menu's are laid out clearer and you may get better support here as that's what most people here will be running. seems odd that trigger wheels would end the support

If you're going to use MAP that's fine - just forget the MAF otherwise you will confuse people.
What does TunerStudio say the MAP value is when the engine is not running?

Update - all sensors and air intake now installed, wiring not yet wrapped. map readings shown
firmware upgrade on hold, not sure how to go about it and don't want to lose the suppliers support!
Started this evening and got past tickover, log shows start about half way through, revving achieved by gently pressing throttle, did notice some clicking, which I think was pinking - hopefully log will show enough for someone to give me some pointers, I am thinking it is running lean, exhaust hopelessly bad, will be taking it off and adding a proper centre box!
when it comes to adjustments some guidance would be appreciated, I see graphs but no idea how to alter the inputs.

s*** attachment quota reached wtf?

He probably wants to charge you for firmware upgrade...

map sensor calibration is not quite rite should read about 100kpa when the engine is not running, air temp sensor needs sorting to and it looks like the alternator is not charging properly best you get is 13v

thanks for getting back, MAP a big problem, I know what the settings are but tuner studio makes no sense to me! its asking for a % input which I don't understand, the MAP is 20-250 kpa and mV396-4610 I did try entering .396V - 4.610 but this was not accepted.
AIT not working? I have 2 available - AIT currently connected from the donor car is located in the air intake by the K & N filter, there is another in the planum (from another donor car) which is not connected as I thought ambient heat would be a problem.
Alternator is currently not connected as it has been suggested that alternator "noise" could be a factor!, battery trickle charged after every workshop session!
This evening I have discovered the reference manual, which may give me some help. I am reading about V tables, if I can get my head around the concepts I may be able to achieve an acceptable tune - at the moment its a whole new language to me - I used to work in a lab creating the machines that made microchips, but at 67 new concepts are hard to grasp.
Once again many thanks for getting back to me - the vendor of my ECU has, this evening, told me its ok to update the firmware - more reading needed!

forgot to answer your previous question, engine is zetec silvertop 2.0, oil pressure and coolant fine, injectors are focus side exit 2.0 rated, plenum is Escort Mk5 1.8 , throttle body is mondeo 2.0. O2 sensor is standard narrowband, ignition is EDIS. fuel is LP pump feeding swirl pot, then filter and 50 psi pump, fuel regulator is standard mondeo

what kpa values does the sensor read @ .396v and what kpa @ 4.610v? have you got a spec sheet for the sensor? yeah your ait is not working/calibrated properly unless its really -23c where you are. when loading new firmware you will get prompted for a version to flash. you want microsquirt cased.

they should show enlighten you on where to calibrate your sensor

i think you may want to invest in a wideband lambda sensor as well

You can't tune with a narrow band sensor.

it just goes on and on - I remember reading right at the start, that users should read all the manuals! A lot of the information is baffling to say the least and the learning curve is very steep!
Discovering that my IAT was producing a temperature reading of -27C was quite a surprise!
While searching for info yesterday evening after a session in the workshop I came across a document not seen before - which mentioned menu items in tuning that should not be modified while the engine is running - pants! I had just done some tweeking not knowing that! - so when I went to the workshop this evening the first start was spectacular! - no computer connected the engine coughed, started and then accelerated like a demon!
presume that's the flash memory garbled! so question is - does the squirt have to be updated or do I just need to connect and burn the values I changed while the engine was running?
