In Reply to: So do you think if i add a bit of increasing load to it, it would help on the overall timing bounces posted by Ah10::HBHotline on 2006-10-10 10:52:17

Depends on where you are on the map and how rapid you're in transition between load points. The increasing loads seem to have the greatest effect as MAF readings climb rapidly.

Need some help again! Got a question regarding overall timing please see log inside - Ah10::HBHotline 2006-10-10 10:14:24 (1531 views)

What is up with the TCD, 12psi? What is the logic behind that? - EdyJun 2006-10-10 12:40:35 (193 views)

why isnt it pegged at 14 psi? - drgolfnut 2006-10-10 13:35:38 (195 views)

may be ambient pressure is greater or less so it doesnt show 14psi - Ah10::HBHotline 2006-10-10 13:56:27 (138 views)

Requested boost tapers to 12 psi. Measured boost higher than requested=throttle cut. - Ochlockonee 2006-10-10 13:44:18 (146 views)

You can easily get away with 1 PSI deviation. The fact is TCD boost setting depends on .... - PSmalls::HBhotline 2006-10-10 13:54:08 (173 views)

I still don't get it! - EdyJun 2006-10-10 16:55:56 (154 views)

Ya. My Vast TCD clamps at 13.8ish psi. Piggie musta used a lower voltage zener diode for his TCD. - Ochlockonee 2006-10-10 19:43:40 (159 views)

Maybe they aren't all exactly the same. Mine was one of the first, Piggie put together random stuff. - PSmalls::HBhotline 2006-10-10 19:17:11 (149 views)

The ECU may be responding proactively to little maf spikes. Try overlaying maf and timing. - Ochlockonee 2006-10-10 11:45:44 (148 views)

Here's the smoothest timing graph I've ever seen. Don't let the CF scaling fool ya- - Ochlockonee 2006-10-10 11:29:32 (245 views)

I've seen cars with CFs pegged at 0 and timing still choppy as a mofo. - PSmalls::HBhotline 2006-10-10 13:54:57 (118 views)

It could be the software (mtm) or some variable that's unseen in the logs. - Ochlockonee 2006-10-10 19:49:48 (135 views)

I think I have a log that CF is 0 all the way, I will look and post it up - S4AVT::ESL 2006-10-10 16:32:02 (126 views)

Dayyyuuuuuummnn! ok.....we need to log my car now!@! ;-P - Yankees:FallenEmpirE 2006-10-10 11:00:12 (156 views)

I wonder why is it doing that! i want to get that smooth before i add timing from lemmi, at zero now - Ah10::HBHotline 2006-10-10 11:01:46 (182 views)

I had the same dips when I was running X on 93... <edit> - Mike2kS4::ASP 2006-10-10 10:38:07 (228 views)

to me it looks like it is on the high side on IAT, sitting in traffic doesnt help either - Ah10::HBHotline 2006-10-10 10:40:40 (151 views)

Yea, I actually figger'd that out and edited a few mins ago. - Mike2kS4::ASP 2006-10-10 10:43:22 (145 views)

so r u saying i shouldnt worry about it & proceed to next step? say add a few degrees of tim - Ah10::HBHotline 2006-10-10 15:50:08 (137 views)

From many of your logs, I've noticed and seem to think I can explain your IAT curves... - PSmalls::HBhotline 2006-10-10 10:41:43 (175 views)

So you're telling me my ECU is dumb and kept overreacting in both directions a million times? - PSmalls::HBhotline 2006-10-10 10:40:34 (153 views)

It reacts, listens and resumes. - Mike2kS4::ASP 2006-10-10 10:45:32 (217 views)

and how do we manipulate fueling in midrange? i thought old k03 x file you cant do that? - Ah10::HBHotline 2006-10-10 10:57:26 (174 views)

Right, the more I look back at my logs the more I think increasing loads my not hit the correct spot - PSmalls::HBhotline 2006-10-10 11:01:23 (179 views)

LOL. - Mike2kS4::ASP 2006-10-10 18:57:11 (149 views)

Woo hoo Mark! if you need my email address please let me know! hehe lol - Ah10::HBHotline 2006-10-10 12:27:58 (148 views)

Have Mark send me over the tools and I'll add a dash of fuel at that point. ;-) - PSmalls::HBhotline 2006-10-10 10:46:58 (164 views)

ahem. cc me plz thx. - nyet 2006-10-10 10:49:15 (125 views)

For 5 easy payments of $299.95, you too can have these tools. </infomercial> - PSmalls::HBhotline 2006-10-10 10:50:48 (169 views)

LOL, I wish. - Mike2kS4::ASP 2006-10-10 18:56:12 (153 views)

LOL fisher price part is funny! hehe - Ah10::HBHotline 2006-10-10 19:33:44 (152 views)

ouch $299.95 x 5? ouch - Ah10::HBHotline 2006-10-10 11:00:47 (117 views)

If it were that cheap, I'd have it already. - PSmalls::HBhotline 2006-10-10 11:01:40 (120 views)

Sure ;) - Mike2kS4::ASP 2006-10-10 10:48:38 (216 views)

hum pulling increasing or adding more fuel on increasing? - Ah10::HBHotline 2006-10-10 20:44:37 (126 views)

+mo - Mike2kS4::ASP 2006-10-10 20:54:19 (125 views)

hehe thank you <3 lol - Ah10::HBHotline 2006-10-10 21:02:20 (142 views)

NP... - Mike2kS4::ASP 2006-10-10 21:04:57 (162 views)

uh oh, option is slim? meaning even if I added fuel back on increasing load it probably wont do - Ah10::HBHotline 2006-10-10 21:08:28 (156 views)

That's what I think... - Mike2kS4::ASP 2006-10-10 21:17:32 (150 views)

that means it works for your car when you went + on inc load, now i have pj k04 - Ah10::HBHotline 2006-10-10 21:22:42 (175 views)

I think the MAF size actually matters as much as the turbos. - Mike2kS4::ASP 2006-10-10 21:24:30 (124 views)

It's not the meat, it's the motion. - PSmalls::HBhotline 2006-10-10 21:28:02 (146 views)

bah. meany - nyet 2006-10-10 10:56:24 (150 views)

So do you think if i add a bit of increasing load to it, it would help on the overall timing bounces - Ah10::HBHotline 2006-10-10 10:52:17 (181 views)

In the bottom-middle of the range it might... - Mike2kS4::ASP 2006-10-10 18:51:10 (146 views)

are you referring to the steep maf g/s climb before 4k rpm? from all my logs seems like it would - Ah10::HBHotline 2006-10-10 19:32:55 (159 views)

I've seen it do something up to 5k... - Mike2kS4::ASP 2006-10-10 19:35:48 (173 views)

larger maf and much lower g/s right? - Ah10::HBHotline 2006-10-10 20:02:05 (137 views)

Yea, and a different load point. - Mike2kS4::ASP 2006-10-10 20:09:26 (138 views)

Right, doubt that increasing loads will work for where I'm knocking (or at least pulling timing) - PSmalls::HBhotline 2006-10-10 19:33:54 (164 views)

But your cylinder might be a bit cooler at those RPM's if your EGT climb starts at a lower point. - Mike2kS4::ASP 2006-10-10 20:01:31 (127 views)

Anything is possible, but I'd say my EGTs are pretty much in check. - PSmalls::HBhotline 2006-10-10 21:09:30 (128 views)

Yea, your car is teh consistent... - Mike2kS4::ASP 2006-10-10 21:21:41 (131 views)

Good point, did not consider that. Next time I try advancing timing with race gas, will do..... - PSmalls::HBhotline 2006-10-10 10:49:55 (159 views)

AWE side mount, are you saying it is super low or high? - Ah10::HBHotline 2006-10-10 10:39:15 (151 views)

nice pull, i need to get ecuX. we have similar times but youre running less boost. - jwolf::ASP S3 2006-10-10 10:27:25 (134 views)

when you get it , let me use it too =) - Farbs | CFDQ 2006-10-10 10:32:29 (138 views)

Heres my best guess and this is really a shot in the dark - BLK01S4::HB B!SH 2006-10-10 10:26:54 (192 views)

Also I'd pull the ecu and let it sit 30 mins w/o power and relog - BLK01S4::HB B!SH 2006-10-10 10:27:42 (138 views)

Is that run with no tweaks, just your normal ~93 oct settings w/ 100 oct in the tank? - B5QShip | CFDQ 2006-10-10 10:22:44 (134 views)

It has tweaks, but what i meant is exact same tweak as if i was running pump gas - Ah10::HBHotline 2006-10-10 10:24:44 (173 views)

gotcha - B5QShip | CFDQ 2006-10-10 10:48:06 (129 views)

Holy crap, hope my car can get that fast on race gas. As for X, seems that it freaks out a bit... - PSmalls::HBhotline 2006-10-10 10:18:25 (252 views)

**channeling STG3S4** NO ITS BECAUSE GIAC SUCKS **/end transmission of STG3S4** - DVS27T::A55clown 2006-10-10 11:56:03 (152 views)

lol it is not, at least from cost stand point! i have had this file for 113k miles ago! hehe - Ah10::HBHotline 2006-10-10 12:23:36 (150 views)

And here with 0 CF almost across the board due to less timing advancement yet still choppy down low. - PSmalls::HBhotline 2006-10-10 10:21:50 (220 views)

I didnt add timing from Lemmi, I think i should, since i dont like to see Zero CF across the board - Ah10::HBHotline 2006-10-10 10:21:21 (167 views)

I talked to Moss about the overall timing bounce, suggested I go to tweaker file with X and XR. - PSmalls::HBhotline 2006-10-10 10:25:22 (253 views)

Are you personifying the software like you mocked me for doing? =p - B5QShip | CFDQ 2006-10-10 10:47:39 (141 views)
