So close to finishing tune, please help
 

Hello,
I have a brainy ms3x and I feel I am almost done tunning this cursed thing. Today I touched up on idle ve, continued messing with the 4 cranking tables: priming, cranking, ase both. Havent touched warmup enrich because that seemed fine.

Now I copied the stock sequential off DIY's site. And brainy's values were close to those, so I just took the ones I thought I needed as they were nicer than the ones I ended up with.

My current condition: after much cranking, It seems that when I went from 8 to 10* btdc it got better and is catching....almost!!:vash:

Below is my msq as I've spent already a few weekends cranking and added significant wear on the starting system.

What seq. injection settings did you copy? I didn't realize you were still having starting issues, what seems to be the issue?

Still having the same sh*t!!! Can't get it to fire correctly. I know cranking pulses are correct because it spins like oem, it just won't catch/go above 300/500rpm. The reason I know this is the ASE green square illuminates after cranking for a few pulses.

bumpity

Can you also post a data log of the problem?

Okay its been another 3-4 months. This is getting ridiculous! Still having issues getting it to start. It cranks fine, its just wont start. Once it starts it runs fine. I really dont know what's holding me up.

Post a datalog.

Okay this from april, probs the same problems from before. And the end of july tune that started up decent with some throttle.

Someone please look at req fuel, ignition cranking settings, and the big 4 cranking pulse, priming pulse, cold start enrichment, ect. (many thanks)

The first log shows sync loss reason 31 when the engine revs up which is a cam signal issue. Also, I found it bizarre that the run bit is Y before the crank bit is Y, and then both bits are Y simultaneously.

Please post a current datalog of the engine cranking and starting from cold with the TPS at 0 using your current tune.
