mappers (autronic)
Right some will of seen my previous posts about the problems ive been having with the focus.
Ive had an on going boost issue and then developed a miss fire when coming off the throttle then back on it.
I was at justins house (b13jus) yesterday fitting my fuel setup and he suggested connecting my ecu to his laptop as he has autronic software.
All we done was look in the errors part and these came up, can anybody give me a run down as to what they are for certain.
They are in order as in the errors list.
The car is booked in to sitech racing on the 3rd of december and i dont want to turn up and not be able to do anything if it needs sensors etc, so id rather try find out before hand.
cheers

don't know this ecu, but does it have a external map sensor? also looks like you have issue with the crank sensor did you look at the settings when connected

yes it does have external map sensor so hoping its actually that one and not summet internal lol, we didnt look at any settings no just hooked it up and found these codes etc.

simon at sitech actually got in touch with me wanting to sort the car out and made me an offer i couldnt refuse

IIRC there was a problem with boost tailing off before, but I'd have expected MAD to give you an idea about what other codes/issues the ECU was throwing up too?? Feel for you Lee, cause the car is on the edge of being absolutely epic, but I just hope you're not disappointed after taking the car all the way up to Sitech.

yes grant thats the problem the boost tailing off, but surely by lookin at them faults its either map sensor or when been mapped the over boost limit hasnt been changed? (hopefully) why would i be disappointed going to simon?

Ive been upto simons when we got my brothers zvh mapped on haltech and simon was really helpfull and explained what he was doing.
Really nice guy who knows what he's doing and will be taking a trip back up to see him in the new year after a few more mods.
I dont think you'll be dissapointed.

What was Simons offer that you couldn't refuse? (oo err

Im no expert but have spent a bit of time on Autronic SMC and SM4 ecu's.... If you look at the age of each fault(in cycles, each start to stop) the baro and manifold pressure faults are all a similar age and the misfire related faults are all similar ages.
The baro, manifold and overboost faults will all be related. The baro press reading is taken on start up from the map sensor, before cranking. The manifold and overboost readings also come from the map sensor while the engine is running. You need to check all wiring and connectors related to the map sensor and then check the sensor is reading correctly by using the laptop and a controlled vaccum and pressure supply, like a mightyvac or similar. It is highly likely the issue is wiring or sensor for this one, especially since you are using an external map sensor, internal map sensors are typically bullet proof in these ecu's.
The other 3 cyl i/p type faults all relate to your crank sensor signal. It is being corrupted through one of the following....wiring issue, elec interference, sensor fault, trigger fault eg gap to big/small or trigger lugs damaged. This will be the source of your missfire.
The boost trailing off could be a map sensor related issue or a mapping issue, you can log a run with the ecu and usually see what is causing the issue if you select the correct items to log.

I will add that If I had a problem with Autronic, it would go straight to Mark Shead @ MAD.

No Problem
FYI, charge temp when talking Autronic ECU's is a programable cross between inlet air temp(sensor in plenum) and coolant temp(head temp). It is used to estimate the amount of heatsoak from the head into the inlet charge under varying rpm and load conditions. I dont think this will have anything to do with the fault codes recorded.

Do you have a mechanical way of altering the cam sensor? Ie is it in a distributor that you can turn for example?
If you can alter it a little and reset the sync values, this may well get rid of the problem, as I have seen similar when the sync isnt in the right range (it quotes the desired optimum in the manual, I dont have it to hand but its something like 50 or so IIRC)
As everyone else has said, take it to Mark as he is the UK distributor for the Autronic so will be in a position of having seen more with errors wether that be hardware or config than anyone else in the country, and as you have already had him do some work on the car it makes even more sense.
How come you are running on an external map sensor not the internal one? They are 4 bar sensors anyway so perfectly well suited to a car running 2 bar of boost or a little more.

As for map sensor chip im not sure tbh hits how it was when i bought the car and i presume its how the car was mapped previously by mark
it could still be a turbo fault as mark said when i took it to him?

If you mean the vacuum pipes? It has one that goes to the external map sensor off the throttle elbow but also has a vacuum pipe from inlet to ecu?

As standard the autronic will only listen to one MAP input at a time, you could add a second if you wanted to also monitor something different (compressor housing pressure to allow you to monitor boost drop in the inlet for example) but given they are both from the same place that wont be the case.

You need to reset the codes and see if they come back,
The mapsensor fault may mean it needs to go back to autronic to fix it but you need to reset to see if its just a small issue,
If you have a loose wire and the ecu turns of and on with the engine still turning is will bring a baro/mapsensor fault. the overboost at the same time could be just a overboost or a ecu swithcing off on boost then reseting the baro and then it will see a overboost if you then go back on boost,
The cranksensor issuse can be caused by a misfire on the 36-1 trigger being more sensative to picking up misfires and showing them as a fault,
Or it could be a back cranksensor/camsensor fault you need to reset these and see if it comes back before a misifre causes it,
To reset these go to ecu error history and press R on the keyboard this willl clear them then go out and test and then recheck or have the laptop live while drive and see if/when it comes back.
