moving on to timing

Unread postby YaBoyHalle » Tue Jan 27, 2015 2:54 am

after optimizing fuel, i believe i can move on to timing.

basically, i added 11 to the whole table, and extra to the top three rows. (30/27/24) it works fine, no pinging, but i want to find out how much i can pull.
without a dyno is there an easy way to find mbt? since my egr broke i'd like to have fuel mileage back near 25 again. i'm going to try adding 14 to the whole table, and also 9, just for comparison purposes. i believe i should want the highest vacuum at stable speed?

also, SPUCLP is max adv allowed in GUFB, but i have no idea if there's a limiter like that in the D9S. i believe last time it wouldn't log past a certain digit. 45 maybe? if all strategies have a limiter like that i'll have to email Glover on the lack of one.

yea all ecu's have a software limiter in there

doesn't sailorbob have the complete d9s def file?

the only way he would is if you convinced him to make one. i checked with sailorbob and pops racing, neither of them had it.

it's a pretty big pain working through this all. PID's mislabeled, functions that don't work. i find the PID on BE12 just to see what the hell it is. i don't understand AD counts, etc, etc. i'd give a kidney for one good definition.

but for now i'll just email Glover for that spark scalar. hopefully he'll have it.

Edit: i sounded too mean. eased up. also, he replied quickly. i'll list the mislabeled PID's and he'll find the spark clip.

an ad count is an analog to digital conversion that the ecu actually uses, 200 ad counts = 1 volt

so 1023 ad counts / 200 = 5.12 volts

120 ad counts / 200 = 0.6 volts

just divide ad counts by 200 and you get voltage

I'd like to help you out and make a def file for that ecu, but its just not worth it being how old it is and that no one uses it, it is 30 year old technology, thats a lot of time to invest with no return

thanks, i guess it was fairly easy then.

that seems to be the consensus. i know of maybe 5 people i could tell and they'd get one, along with everyone with a low output car that swaps in the entire M7 wiring harness and engine. they're probably be more, but it's been hard coded into that community that a MAF swap will be needed at some point. and a few already have a Tweecer, too. i'm curious, what makes it worth it? is it more people or money?

no not money youll never get anything appreciable for the time you'll invest decoding it

I can't speak for others, but me personally, someone would have to offer me $1,000 to even consider making a def for it
and at that theres no guarantees on the depth of it until you actually start figuring out what its doing

Is there any reason why folks choose not to swp ecus ?

Well I was expecting to hear 2k so I guess it could be worse. And as long as you go far enough to include the spark clip, you've probably done enough lol.

Between the mk7 to gufb?
I believe its usually for simplicity. Especially since the cruise control is in the eec. They also like to keep everything seemingly stock. They're not like mustangs where you want it mean looking and lopey, with a plastic interior and constantly broken switches.
I at least thing that its as good an option, if not better than, GUFB. Not to mention the mpg bump, without pulling all the spark I could.

thats cool, the spark clip should be pretty straight forward shouldnt be too difficult to find after you find the spark register

I have my own alpha-n code I use for speed density, if i were to write a def I would include it in it as well, that way boosted setups and what not wouldnt need a maf swap to be efficient

i would also include a base tune for stock setups to take all the guess work out of it

Oh! Yeah, I get you. He shouldn't take too long then. I know a guy has a d9s with a kenne bell, just plugs the map at atmo and uses the fuel disc under boost.

I actually use a close clone of your fuel setup from gufb for mine. Works great, basically spot on for start up.

alright, he's added it. to quote the man,
"Sadly, the D9S is a bit of a step-child strategy. It is **KIND OF** similar to DA1 / A9L strategies, but has some holes where things were done completely different."
and the spark limit was at.... 42! way too low. that was even cutting into slight accels. everything at 18 and below on the MAP would have been cut off.

so now that i can fully test out timing, max vacuum at constant speed?

yep pretty much, you can also use throttle position, the timing that lets you maintain a specific speed with the lowest tp will be optimal

Always wished that BE or Tunerpro would accept an input such as a potentiometer and constantly updated the highlighted cell in response to it real time. It would literally be 'dialing' it in. I think we could do things much faster. Hmm wonder if this is worth of a suggestion.

for spark? that would be pretty sweet. you could fill in half the graph cruising through the gears. too bad i have CalEdit. still, you could suggest it.

anywho, this is my basic spark table as is. 91 oct, it's a mix between the stock D9S, decipha's A9L2, and the MBT on the reference page.
