OK, I'm going to try something else and send out another test version...

[ShelGame]

I sent you guys a new version to try out. I found the reason for the no-start, another dis-assembly error (well, I forgot to convert some data from literal to referenced values...). Try it out and let me know how it works. I'm hoping it at least starts now...

[shackwrrr]

yeah i tried out the latest one you emailed me. still getting the same result of quick prime, crank no start for both the stock and mp atx ones. no errors on the mp one tho like last time. wasnt able to check spark as i was cranking tho as i did not have a helper.

That was the same problem I was having with the cal that Rob sent me. So hopefully the new version fixes that for me. Thanks for all the help Rob

[ShelGame]

Well, the version I sent the volunteer tester last night definitely had a problem that would cause a no-start as I had code branching into unknown territory - could've been the middle of another block of code. That is fixed now. But that doesn't mean there aren't other issues to sort out. I do have confidence that it should be correct now, but you never know until you try...

I'll get a new chip out to you as soon as I can get confirmation that it's working now.

[AzShadow]

the latest version (emailed out oct 19th) yielded the same results...

i am however playing with a an older version (maybe 3 or 4 iterations ago?) that seems to run the car pretty well. just trying to get a feel for how to adjust things with it.

[ShelGame]

Let me know which version it is that runs well. I can compare them and maybe figure it out...

[AzShadow]

version 2.2

edit* using the stock atx template btw

[ShelGame]

Hmm, v2.2 really shouldn't run right. It's got some bad code in it...

strange for sure...

anybody else try the new code out?

[ShelGame]

OK, found a couple of issues still in there. I need to put the code 'back together' for T-SBEC and I'll send out a new version to try...

[ShelGame]

OK, new test version sent out...

[AzShadow]

same symptoms still.... anybody else try out the latest???

[ShelGame]

What are the exact symptoms.

[AzShadow]

Fuel pump primes for a split second, crank, no start.

[ShelGame]

Do you hear the injectors fire off the prime pulse when the fuel pump/ASD cycles?

[ShelGame]

Also, will it flash out codes? If so, let me know which ones it has. Might be a clue in there what's going on...

[AzShadow]

im always in the car when i turn the key on so idk about hearing the injectors fire.. is this something i can hear or how do i check this?

also, im not getting a cel, but i can certainly hook up my scanner and see if its throwing any codes

[ShelGame]

You can try the scanner, too. Mostly, I wanted to know if it will flash the codes out the CEL. You should get at least a 12 and a 55. That will tell me if the main program loop is running, or if the code is hung up somewhere else, possibly on initialization. If the scanner communicates with the ECU, that pretty much tells me the same thing.

So far, just looking thru the code, I can't see why it would not start. I did find a couple more small errors, but nothing that should cause a no-start...

[ShelGame]

I found a potentially huge problem. There is a minimum injector PW for distributor sync. I converted this to a constant value so that it could be adjusted for injector sizing. However, I wrote the definition wrong in the asm file. It was using an insanely high # for the minimum PW. So, I fixed that (and a couple of other minor issues) and sent out a new version to test. Let me know how the new one works out...

[zin]

I found a potentially huge problem. There is a minimum injector PW for distributor sync.

Wow, they really set a minimum PW?... Does the math potentially have the injectors running negative or something?

Just showing my ignorance of the binary world!

PS I was looking for my favorite calculator (NS1 for years), and noticed a calculator that either worked in binary or converted... Is that something you would have use of? If so I can make an effort to remember the model number the next time I happen to see one...
