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 (196 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 (147 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 (155 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 (146 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 (138 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 (180 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 (149 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 (176 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 (138 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 (128 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 (132 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)
