cp-e Full Control

[Haltech]

oh it will make more power, there is no fuckin doubt. i want to see how the standback is going to play a roll in all of this. Please tell me, that we can now get some good timing bumps and the computer is finally going to get on all 4's and take it in the ass like it should!

meth + timing = major hp

throttle open + big turbo = major hp

fully programmable ecu/piggy solution = major horsepower

Big Turbo + Meth + Major Timing + Fully Programmable Ecu/Piggy = 450 Hp

[TRU-BOOST]

17psi till redline make good power even on a stock turbo. hell with my mbc i hold run 21psi that falls to 16psi at about 6300rpm. i want to hold my 20psi till redline !! everyone knows i am by no means a cpe fan, but this may be a RARE exception !! this is all i want...throttle control !! if i can get that flashed to my ecu and still run a <AP clam[p and MBC and save myself a SHIT-TON of $$, they by GOD thats what i will do!!

[TotallyNotAmused]

Do you know if they will be marketing a simple hot flash for someone who wants a little more than what the basic flash offers, but isn't really looking for going all out with a Standback?

[Redsand426]

^ the flash is the same with or without a standback.

So Thursday night Lou flashed my ecu. It was his first attempt and it was based on his understanding of the MS3 ecu. We pulled mine and he read it, disassembled it in his software and found the throttle plate tables that he modified for the MS3. Took about 30 minutes. Here's the result:


This is the log I took on the way over so stock TP.


We thought the DH was reading funny so I logged it again the next day with the standback.


Sure enough, the throttle is better but it's still closing at 5500. I spent some time looking at it and realized that it closed very similarly to the stock TP control after 5500. That lead us to think we hadn't quite covered the appropriate portions of the TP table. Here's an excel comparison of the two DH logs



We edited the table and flashed again. Here's the result:


Better but still closing after 6000 rpm.
One more edit and here you go:


As you can see, cp-e has completely eliminated the throttle limitation. Additionally, the tables edited for the throttle plate control are untouched in both COBB's and Piasini's flashes... That's an absolute fact.

[surfwagon]

This is really good! Thank you cp-e. I cannot wait to the flash + standback in action. Hell yes!!!!!!

[ztuner]

NICE - i'd say thats a good breakthru.

[Haltech]

So how did the car react to the open throttle now?

[dadasracecar]

I feel like it pulls much harder. Extreme is closed this weekend for racing this weekend so no dynos. I wish. I was really nervous about flooring it and holding that far but the AFRs are in the 9s. I zeroed my tune for this so I'm way rich again. I'll need to pull it back to the 12s for a fair comparison. Nevertheless, it's faster than it was pre flash when I was in the 12s.

[Haltech]

How is the K04 holding up with boost up that high with the throttle wide open? Can't wait to see you go back to your reg tune to see what you may have picked up.

[Laloosh]

omg i cant wait....here my meth log
16 degrees of timing mid 12s through 4th gear, no knock
Now if i can just keep the throttle open i have a 115mph 100 percent.

[Haltech]

Chris, whats with the hump at 13 afr 10.5 seconds into the run?

[Laloosh]

that would be me overspraying the meth...it bogs and the throttle does its lil dance

You're getting bog right after the gear shift?

[Darksun280]

I get it alot of the time right after the 3rd-4th shift.

[TRU-BOOST]

aaahhhh crap i might have to break my boycott !

[Laloosh]

no, the only time i get bog is downlow aroun d3k rpm. If u look at the beginning of the graph, notice how timing takes a tip cause the car begins to really drop the a/f fast. I never get bogging on a gear shift. The reason its at 10.5 is because im shifting. And im back to full recirc 2, which is funny cause i was maybe .5 richer completly vta

[Haltech]

Thats weird.. It starts out like ballpark 12ish, than goes higher after gear change to 12.5 than dips back down below 12 on the next gear shift. Fuckin Ecu...

no cp-e for thee...

[Laloosh]

dude ive been bitching about this for MONTHS
4th runs leaner then when u shift into it as apposed to starting in it.
Also the computer has set timing per gear
set a/f per gear depending on rpm


as for the dip in 4th gear about 6200, that just the throttle closing, which once again changes things differently depending on what gear your in. I rode out everything till 6500, it didnt happen in 2nd, didnt happen in 3rd, a/f droped in 4th at 6200 but ran a lot leaner everywhere else, didnt happen in 5th, and believe it or not i pegged it 2 nights in 6th and it didnt happen

[Haltech]

Hmm, ill do a few runs today and see what my graphs look like. Im very curious now. Just for reference, what temp was it outside when you did that run?

[Laloosh]

75ish

you on the 2 nozzle now? All in a sudden my car started like the meth. it only bogs a little if i try a 3rd gear roll to low. everything else works fine though. who knows......

[Haltech]

Yea, im starting with the #2 to see how the car reacts. I want to see if there is a big difference between D03 and D02.

when you look at how much it flows it wasn't too much of a difference so i said fuck it. Like i said car started accepting it for what ever reason

Just do it. No reason for it anymore. I have a bunch a CPE stuff for my car and I spoke with Josh and they are gonna flach my ECU pretty dang soon.

[ATE BALLER]

Yeah, they're kind of grabbing the market by the nutsack with the throttle flash.

Dada your thrd graph of the DH the one where you edited.... Is that actual throttle sensor position?

[TRU-BOOST]

i noticed that too it says "commanded throttle" i never logged that before. i dont know if that shows pedal position or throttle blade opening. and i have this question....
if they have this throttle control, why do i still not see 100% throttle ?? sure 80% across the board is better, but not what i want to see !

[NYpest]

Also dada, do you know if the flash going able to tame that crazy lean hump?

[dadasracecar]

You have to remember that the values in the dashhawk are scaled by a human to the tps voltage. I don't really know what the numbers mean. The stuff from the standback - which is harder to log with than the dashhawk and why I have soo many DH logs - only logs the tps voltage. That is the actual voltage. No scaling. When I plugged my DH in again after the first download it switched to metric units and must have changed that throttle variable to commanded throttle position instead of absolute TPS as it was originally. The only thing that changed with that was the numbers on the axis. Other than that the shape of the line was the same so I never changed it back.

As far is the lean hump is concerned it's still there. Based on Laloosh's advice I start my runs at <3K rpm now and the hump is not as bad but it's there. That will be address in the later closed loop to open loop transition modifications that Lou is planning. For now, I'll try and tune it out with the SB as much as possible.

I did a run today with a zero map and my afrs are 10.3ish. It still pulls harder than before but now I'm pulling fuel to get it back to the 12s. My car is pulling (for me) like a raped ape. I love it. Laloosh, get down here now.

[94jedi]

dada, where in the DC metro area are you from? My family is in rockville where I grew up but I came out to the eastern shore for an IT job (backwards, I know lol)and my wife's family. I've been trying to get together w/ Pale, Loosh, SgtP, and the others for some time now. Let me know when you all do get together and hopefully something DOESN'T come up on my end.

Dada...maybe i missed it but are guys gonna hit the dyno for this. That would be the NAIL IN THE COFFIN.

[Lex]

I think a dyno before and after the change is essential. I have a feeling there won't be much more to gain from the stock turbo at 6700 rpm. Perhaps 20 horses. Also please post intake air temps - they would tell us how efficiently the turbo is running.

[dadasracecar]

Extreme was closed last weekend for racing and they have limited days this week as they're going on vacation for the fourth. I've put a call in and said I do it any time they have available and am waiting to hear back. NO ONE wants this more than me.

As far as the boost temps are concerned charles (ms6) ran a 1-2-3 at WOT to 6500 in each gear and saw about a 10-15 deg rise in boost temps with his ETS TMIC. Seems the turbo is holding up fine.

[SSinstaller]

Dada, your pretty close with everyone at cp-e, is there any way you could convince them to delete MILs for the EGR and cats in the flash??

[dadasracecar]

Good idea. I've already put in a request for the VTCS... Lou is looking at your workaround for me until then.

[Laloosh]

im going to have to drive up saturday lol. I want this flash bad. 600 mile round trip worth it.

[Haltech]

Chris, just steal Randy's transmount while you are there. Kill 2 birds with one stone

[Laloosh]

now ure talking!!!
