new $EE tuning thing!

**steveo** · 12-20-2015

cool! thanks for the clarification.

i'll probably add lamp control testing in this version, but in the next version i'll use them for something really interesting, flashing the CEL when knock is logged would be a cool idea? (we could hard patch a modification like that too)

im not sure if tcc lockup will be in the next version or not, but it's probably really handy to be able to disable it during logging runs.

do you know if the skip shift lamp is wired to anything in automatic transmission harnesses?

There are some empty strings verified If you want to use them for other purposes.

a maf/speed density switch is honestly the only thing missing from mode4 that i'd find useful

I can try to make a patch for that, if you are intersted implementing it.

Finally I managed to find the soft switch for fuel pump. All by chance of course.
It is located at eside word_180c. It is a pwm channel but only on off positions are used. No mode 4 control for that though.

awesome! that'll be very useful in the future. I bet your disassembly is looking great with all these addresses labelled properly.

Steve I'm going to try this out on a '94 Roadmaster wagon tomorrow. I'm looking forward to trying it out; the last time I touched a tune was way too long ago!

Guys,

1. I watched a GM tech use the Tech2 to force line pressure to commanded values after a new 4L60E was installed to verify that line pressure was what it should be. Is there any way to add this functionality into eehack?

2. Is there documentation of autospark somewhere that I can read?

yes, but you'll have to be patient, i just added the first automatic transmission functions last week

no, but it should be completely self explanatory, also the 'documentation' for eehack is all in tooltips (hover your mouse over an option to get help)

if you have any questions about how it works, let me know

4.0 beta 2: http://fbodytech.com/download/223/

- fixed lots of small bugs
- added wideband "display" smoothing within a threshold (so low airflow readings are actually readable, if your controller is poor and doesn't average on its own like mine)
- fixed bug in wideband analyzer
- faster flashing (at least 30 seconds less time spent per side) (optional)
- safer 'recovery' mode for flashing in case anything goes wrong, uses REALLY safe but super slow default serial timing
- might have fixed the speed logging mode (it was broken before)

this thing is a monster now. so far 33,000+ lines of c++ code and 13,000+ lines of ui definition.

it would be nice if a volunteer would go over my 'tooltip operators manual' to see if there's any big omissions or errors. any takers?

Just did two successful flashes to two different PCMs using eehack 4.0 Beta1 on a Dell Laptop running Windows 10 through an Arduino board and a standalone harness that looks very similar to yours. I did not try any of the accelerated stuff; I'm in the middle of nowhere right now.

**sherlock9c1** · 12-22-2015

On the extended tab, I think the BLM cell labels in the middle are reversed.

you mean reversed left and right? or 0-18? it's certainly possible. i'm an open loop kinda guy, so i never really tested it beyond it reading a bunch of 128s, so if you could confirm that, i'd really appreciate it.

awesome! that acceleration stuff is pretty safe, in beta 2 it's enabled by default.

This will probably help me a lot, as my gauge seems to average, but the analog out for datalogging jumps around a lot at idle.

it'll be double that soon.
lol

I'll be happy to look through it, but it will have to wait til next week, this week's a bit hectic.

that seems typical.

it's working well for me, at least well enough to make it readable, but please test it and let me know if it's alright. right now it uses (non-configurable) 8 records in a non-weighted average (and at average logging rates, that's about 3/4sec of averaging..) but i could increase that at the expense of response time.
