thanks, i bought the parts today, and ill give it a go this weekend... but its the GF's birthday and i already copped alot of trouble for working on the car late into the nights recently... so hopefully ill get to sneek away at some stage, lol.

would it possibly be a poop ground? i know iv checked them, but im going to check them again, and re run them to multiple places. id guess that would cause the engine to be affected with the spikes.

iv just watched the log with secL, and i do see what you mean. throughout the log, it only spikes ...

thanks matt,

problem is i dont only get issues witht he resets, i get them throughout the log, and where the spikes are affect the engine, i can feel the spikes like a miss in the ignition or similar. but a miss in the ignition system wouldnt cause everything to spike would it? even my clt sensor ...

bump? any more news yet? i told the gf i want her old phone [galaxy S] when an android app comes out, and because i dont use a phone anymore since my last died [i call it my leash... ] she's whinging for me to get a phone or pay for her upgrade to a galaxy S2 so i get her old one.

heres my most recent log, taken yesterday.

look at around record 1290 onwards, see the spikes or drop-outs there?? could that be noise? i never had this issue the last time the car was running... it shows up a couple of times through out the log.

what are the "mark 001 reset"s? there is 4 of them ...

hi again, been awhile since iv had the alfa going due to cam problems [now fixed, i hope... ill find out in about 1000kms. last one wernt hardened properly :x , the second ones wernt even for the correct engine :evil: ].
iv still got the stutter around 1500~1700, and a smaller stutter at idle, but ...

heres a log i made on the way home, from mum and dads, tonight. should show my problems.

cool, i thought id try some different sized seners. ill give that a go and get back to you's

a log i made this morning to work, the rpm range is between 1500 to 1700 and a split second before the 'miss' [or leaning out of the 02] rpm spikes downwards to 800, or 500 if its a bigger 'miss' [bigger miss = leaner spike]. looks like tacho drop out? seems to follow my problem quite regularly.

what the heck?
dont know why it started but all of a sudden it says

problem loading project.
reported error:
peojct corrupt, no configuration options found.

then i click 'ok'

then
would you like to update controller econfiguration file?
yes / no

this happens with or with out the megasquirt ...

right-o,
since fixing the spikes, its revealed a missing feeling at light cruise and light accel. the WB 02 is reading about 13.5~14.5 when it happens and sometimes seems to jump to 19~20 for a split second, most of the time it doesnt stay long enough to read. happens from 1300 to 2000rpm ish.
up ...

thanks, using a 20v zener diode worked a treat.

v2.2
so they are tach spikes?

hi guys,
iv got my ms1 up and running, pretty well when it gets up and moves, but i know theres more left to tune out of it.

im having trouble with getting it to idle well just after starting. usually when cold, but sometime when warmed up too. iv been playing alot with the after start enrich and ...

i was just reading the mega manual and found a section on IAT sensors saying that they can be found in the Buick engines up to 1996. this would be the VN to VR commodore in australia, and iv got 2 or three spare engines at home... horrible things they are...

can anyone give me the part numer for the gm IAT sensor, solid end, or even a model of car they were used in [austalian delivered would be ideal]?

thanks

thanks bud, i checked it, and it looked great, as new infact, zip lock bag and all... so i installed it and everthing tested fine

hi guys,

this is my first build, and iv just got to the first stage of testing with the megastim, and after checking all the boxes in the manual iv printed out, pin1 has no voltage/signal when connected with pin 2, 19 and 32.

sometimes between pin 1 and 19 the voltage will jump to about 4~5v and ...
