DTAForum.com - a forum for the DTA ECU

To be clear the first thing i did beforebstarting in the first place was drain all fuel and renew the pump filters and fresh fuel before starting. Than i cleaned injectors and tested them too.

So the answer to my question twice where you said nothing had changed from it working previously........something had in fact changed. It is unlikely spark plugs will cause the engine to start briefly, then stall. More likely it is not getting a suitable amount of fuel/air if you have now confirmed...

The problem is the original map was overwritten when i started entering the ecu as i saved the ecu map b4 i started. I realise i should have renamed it and backup that way to keep history. Engine now starts but stalls within half a second. Waiting for sparkplugs. Fuelpressure and injectors work so i...

did you personally have this as a good running setup before it was parked up over that time and know 100% it was never touched

100% never touched the dta from dtawin

I have managed to get spark on cranking now. The settings one coil per plug and unequal firing in the unequal firing settings window seem to have changed. There were on yes and after changed to no i had spark. Ticking twinspark makes no difference. Car made intentions to start but dont get it runnin...

ok step further now, settings in the unequal firing angels box were set to yes ("unequal firing" and "one coil per plug"). Ive set them to no and coils now do fire at cranking. engine almost starts for half a second but cutsoff immediatly. Checked sparkplugs, black and dry so nex...

ive tried it ticking twinspark , still no difference. Ill measure coilvoltage DURING cranking, I really do have a good battery even on constamt charge and have cleaned main ground . It may be a ground issue anyway but Ill look into that. DTA gets 12V for sure as everything works and no red screen or...

Yes its always run without camsensor on 1 coil per plug. Its not a twinspart engine.
Heres my general settings

i mean during cranking the rpm in the testscreen shows around 200rpm, ofcourse not steady but around that figure and no there is no spark during cranking. Just at the moment I stop cranking theres 1 spark.

i did run the coils injector test (fuelpump off ofcourse). It tests in steps of 1000rpm till max rpm, than repeats. During the test the coils do spark as should and injectors work. the only suspectable issue could be the crank sensor but it does give the rpm to the dta and tacho and when the car was...
