Simon. To clarify this. You are saying you can SAVE the locked map and load it back in later if needed. But can you READ it?
-
No. If you could do that there would be no point in passwordprotecting the ecu.
Only thing you can do is resetting it and start over.
-
Yes you will probably need to fudge it around a bit to get it right. I was just guessing on the numbers as i dont really know the engine.
You also probably need to alter the idle solenoids dutycycle so it doesnt let to much or to little air by. It is a balancing act this.
You should really try to turn OFF the idle ignition map and get it to idle as good as you can with the main ignition+fuel map and ISC dutycycle first. THEN turn on the idle ignition map as an aid.
The main problem is that when it is hunting it goes in and out of idle state. Switching between your idle ign map and the main ign map. When there is a large difference between them this is what happens. You could also try to lower the numbers in the main ign map that is reached when it hunts to try to stabilise it that way.
-
Try this one on for size. Just adjusted the timing map a little and did some changes to the idle ignition map.
-
Just try something from say -5 - 10 degrees. Its just to get it going.
-
Could be a timing problem you are having. To much timing at idle tend to bump the revs and you end up with hunting. A log will show this.

Switch off i-knock trim meens no knock control... Intentional?
-
40 iirc on the pc and 100 in the ecu

Ah. Thank you. Seing your post made me wonder as well. spent a good while googeling with no result.

You need to verify your ignition with a timinglight regardless. Do that with the injectors switched of first. Then again when running.
-
Have you tried adding/retracting 360 degrees to your timing offset? Could be firing 360 degrees off.
-
Does it run when it shows lean?
-
You have CAN on the storm, right? I would suggest you find a controller with CAN output and use that instead of a 0-5v signal. Can is not affected by "ground offset". But yeah, age might be a factor also.
There are several vendors offering these.. AEM, Motec, KMS, Emtron, Ecotrons to name a few
-
Normaly/theoreticaly set to zero. But it might be nessesairy to have some small adjustments on it anyway. Same applies to the warmupenrichment.
(When chargetemp approximation is on)
If you need some ideas on how to tune the chargetemp correction table look over at hpacademy.com. There was a webinar not to long ago on this
-
Are you able to use the on-board scope while cranking? If so that should give some clues of arming thresholds in case that is your issue.
Also make sure anti theft isnt enabled or some crap like that..
-
Well you are out... You got 12 to play with on the G4, thats it. Look at the menu under "table allocation" and you`ll see whats it all about.
Upgrade to a G4+ and you get 30 "tables" to play with.
Thats one of the downsides with this thing...
-
You got "slop" in the system between the crank itself (what we want to meassure the position of) and the actual trigger system (that tells the ecu where it THINKS the crank is at). This slop is what the ragged rpm graph tells a story about.. Its good enough to use as cam signal as long as you can make sure it fires between two crank teeth but not good for CRANK measuring.
-
That was my suggestion for you. The problem is timing scatter. Only way to fix is a triggerwheel on the crank
-
Huh? That....doesnt make sense.
How long does it take to fire it? Shouldnt take more than like 2 crank revolutions for it to synk up and fire.
The prime is only to make sure there is pressure in the fuelsystem before you crank it. 5 secs should be more than enough. Also the pump should start once you crank it.
I guess it is log posting time again mate. Make a log of cranking and starting and lets see whats going on...
-
Weird. A friend of mine emailed me a day or two ago with a simlar, of not the same, problem where AFTER cranking it one of the banks (v6) coils were getting hot and there was clicking noises also. He said it came from the coils, but could also be injectors. I dont know yet. Hel also had to yank the ecu out of its sockets or pull the main power of it to stop the issue... Hmmm :/
-
Hi there.
It takes longer to start now as the ecu needs to know where the cylinders are at. This now takes longer as the ecu only gets ONE synksignal from the cam where before it had 6 different lenght synk patterns in the triggerdisk.. A cam LEVEL pattern on the cam will shorten your startup if that is really important.
Prime time is under YOUR aux outputs - aux 6..
Save locked ecu map

Thanks for the schooling...
