Truth be told, I only tried v403 for about a day as I preferred the older map and maybe I didn't let it adapt though...

I think the weather is as bad (summer), around 25-30 degrees C.

Is there nothing else I can do about the timing pull beside getting FMIC?

I've sent the log to COBB and still waiting their reply.
A good guideline is, 3.38* or less across 3 or less cylinders. For timing corrections. If you start seeing higher.timing pulls consistently on the same cylinder, you can swap coils and see if it follows, if it does get a new coil, if not maybe a new spark plug. Even the stock setup.has timing pulls. I was getting higher than 4.xx on cyl 2, eventually. I got a misfire, swap coils, it followed, changed the coil, fixed the issue.

You are good.with 98 Ron.

Just for kicks, do you have VD graphs showing 402 vs 403? That seems to be a big difference. Let it adapt, usually a newer version means smoother and happier car, but maybe not. It shouldn't take much for the car to adapt to a new version just a couple WOT.

Could you post up a couple datalogs of the 4.03 map? It sounds like you were either having corrections or your CATs were high and that was causing the DME to pull back on the timing.

So these are my two datalogs from last night with v. 4.02 Stage 2 + FMIC.

Anybody see any issues with these?

Mods are: Vishnu DCI's, VRSF FMIC, VRSF catless DP's, VRSF exhaust.

Was considering raising the load target above 5000rpm to 6500rpm to 190 to try to hold on to some top end power, and maybe adding 1 degree of timing in the 180 load column. Most of the time in 3rd/4th I shift the car at 6000rpm anyway.

The second run was about 10 seconds after the first, I did one third gear pull, logged it, then did another pull right after braking down.

Edit: In the second datalog, the timing corrections were in cylinders 1, 2, & 5, and were only 3.38 degrees each

Thanks for any input

The logs looked solid. Like you said you had a couple corrections in the second log but nothing to fret over. Also, you weren't having overboost induced throttle closures that a lot of people are having with the + maps so that's good.

You could definitely experiment around with ATR to see what you can do. With my car on 93 i've found it beneficial to actually pull a little boost out and bump up the timing a little, but different cars respond differently so you may able to just bump up the timing a touch without having to drop the boost.

If you up the load a bit and don't touch timing, whats the result? Will it try to keep boost higher or will it give more timing than the timing table suggests to make up the load difference?

Upping requested load just requests more boost. It will not run more timing to meet load targets because load is determined by RPM, TPs and MAF(boost)

However, upping requested load can affect timing but not like you're thinking. When you change requested load(up or down) then you change actual load. Actual load determines timing(as you can see when you look at the main timing table.) So, just keep in the timing table in mind when adjusting the load table.

Has anyone tried Cobb E30 v4.03 w/ stock pipes and exhaust

I'm running Stg1+FMIC and have access to E85...anyone try the E30 map with stock exhaust? Any issues? Thanks.

I'm not running COBB's E30 Map, but I have an E85 ProTune that's for ~40% Ethanol with the Stock CBE (catless DPs). If you're gonna buy E85, I highly recommend buying from the Shell on Vine Street in Philly

Thanks. I've been there twice. I'm not sure if I want to push the ethanol content that high...concerned about long-term ethanol corrosion issues...
Right now I'm running a summer PTF e-tune from Jake that's been starting to pull timing now (-6, -8 degrees) in the colder weather, so I threw in a few gallons of E85 with a Vpower fill-up and everything settled down nicely. Since I'm already at ca. E25, another gallon of E85 brings me to E30, but the Cobb OTS E30 map requires DP...

Most likely your ProTune runs similar timing as our OTS E30 map, so I doubt there would be much if any gain from going with our OTS. Jake is a good guy and I'm sure he could let you know if there's more to be had.

The 403 maps are the same as 402 as far as timing goes. We upped the version when they went from beta to release. We tweaked the WGDC table for some overshoots we were seeing, but even 91 customers seemed to have solid timing logs if using a proper mix, so we approved them for 91 as well. Keep in mind that these maps are really aggressive regardless, so make sure you log. If you're seeing corrections, you can use ATR to pull some timing, or contact one of our ProTuners if you want as much power as possible for a specific car.

Let me get this straight, in order to run the COBB OTS E-30 v403 Map.

To get 30% Ethanol with California ACN91 & E85. I should mix 50% E85 & 50% ACN91 correct?

No,

E30 means 30% ethanol. Which is at min. 4.25 gallons of E85 to a full tank. With 91 you may have to mix slightly more. Based upon 91 having 10% ethanol.

But log to be sure.

http://www.intercepteft.com/calc.html. Use this calculator at the bottom. E85 is 96 AKI octane to 91 octane AKI..

Which comes to about 92.3 AKI octane.

The AP does display boost in PSIg. It displays boost mean abs and requested boost in PSI.
EDIT: What VNeBLOB said below. Select "? Access port" then "settings" then "units" and then "standard."

Yes, I believe it's under one of the menus on the AP. can't remember what it's called. But I believe it's either metric or standard overall. Not sure if you can changed just 1 entity.

Cobb, please remove this useless cat warm-up cycle. I'm catless and my neighbors will kill me one day. Half the village awakes every morning when I start my car.

I actually ran 50/50 E85/ACN91 for a month and it pulled hard. I logged a few times and timing seemed good and the LTFT/STFT did not exceed 32%.

Would it cause any harm to run that high of a mix?

According to the calculator you linked I should be mixing 9 gallons of 91 & 5 gallons of E85 to get 36.5%. (I'd like to run 5% higher ethanol content as a buffer).
