Anyone street tune using the CP-E

[Haltech]

I understand that but I'm not making drastic changes. my map is far less aggressive then the map cpe recommends for my mods. I'm not really tunning, more like fixing lol

I understand where youre coming from but if you get a LM16, you can datalog the run and figure out where your problem is. You maybe running lean at one particular rpm point than going rich 500 rpm up from that. It sure as hell will help you pinpoint the area you need to fix.

I still can't believe that any one would tune without knowing everything from long term knock retard, to what there A/F ratios are. I also can't believe that a sophisticated (thanks to those who noticed my spelling error) unit, that cost $600 and has the ability to change with in such fine measurements doesn't log.

The standback shouldnt need to datalog. infact, unless you have a wideband, where is it going to get its data? Via onboard sensors? That isnt going to tell you what you need to know as far as tuning for safe power like a wideband does. Ive learned in my tuning challenges, that the best wideband setup gets you the best results. IE: LM16 Datalogging ablities is impressive and thats the only place im pulling my data to tune off of. Spend the $500 for the kit and you will wonder why you didnt do it sooner.

I run this monster and it cant be beat:
XD-16 With Datalogging

If you want to save yourself $100, go with this one:

Lc-1 With Datalogging

i just really dont feel like taking off my downpipe.
Neway we are tunning craigs car today on the highway. Ill save his tune and try it on my car and see what happens.

You dont need to take the downpipe off to put a wideband in

hey laloosh OMG u are sooo right, i pulled a s*** load of fuel out in the higher rpm's and OMG this thing PULLS so hard
i cant keep it straight

man could you give me some tips on how to do what you did? ive never even plugged the stanback in or know what to do etc. My car is running fine but sound like ya'll got the e-ticket to some more power and I want in!!!(cool) wish we all lived close together(drive)

 

[Powerslave]

hey finkle you too any advise is appreciated!, I don't have a lap top that why iv'e never plugged her in....

 

[Powerslave]

whooops yall posted some good info already sorry for not reading the whole thread

 

[laloosh]

well i plugged in my tune into craigs car, keep in mind he has a ms cai and it runs lean and throwns lean codes. Cpe told him to play with the maf setting and add 1.5 to them and the lean code goes away. My tune on his car was spot on, i didnt change anything. 11.6-12.0 after 4krpm going down to 11.4ish by 6k. Before 4k rpm it was hitting 12.0-12.5 but my tune adds 3 percent fuel from 2800-3800rpm, we didnt add more cause the pump simply cant supply the fuel. I was pretty happy with the results.

you do if you have a catted dp.

that sux...

that make 3 of us leaning out the higher rpm....did you do the exact amount like laloosh or something different?

Those that are worried about fooling with the downpipe if you have the high flow cat could just buy the dashhawk for about 300 and get pinpoint accurate results. I have the dashhawk and have it set up for cat temps, Boost, and A/F. Hell of a lot easier to install and very reliable.

I have the standback and I basically street tuned it with my lc-1 wideband. I dont get any fuel cut or studdering. I love the standback ems and it is so easy to use. If anyone has these mods let me know and I will send you my map. Injen Cai, cp-e TBE, Forge bpv, cp-e standback. I havent messed around with timing yet but fuel is reallly easy to tune. At fuel throttle my wideband numbers are right around 11.5 to 12.1. The standback logs the throttle position sensor volts and your engine rpms. My wideband logs my air/fuel ratio so all I basically have to do is go back and look at those 3 aspects and add and remove fuel where it is needed. If anyone has any questions or needs any help let me know.

griffey... i have ms3 w/ injen cai, turboxs tbe, HKS bov, and boost gauge. i just recently bought the cpe standback to hopefully get my car to stop fuel cutting. ive been running super lean (14.5) so it definately needs tuned and i was hoping to get some info... install or tuning both would be helpful

thanks

I'm more familiar with tuning using the DiobloSport unit on the Dodge Chargers And Magnums. The unit allows 45 minutes of logging any six sensors or you can opt for laptop data logging and log up to 20 sensors with your laptop recording the info.

I have to see what the LM16 kit is. Sounds like a worth while investment..

As I understand WOT tuning is less important on a turbo car than part throttle tuning. Is this true?

Since you claim to know how to tune, would you mind making a how to and sticky it? Many people would appreciate it.

EDIT: As for detecting knock, what device should be used?

Sorry the net was down at my plaec, moving into a new place with the wife lol

Right now i've only pulled out what laloosh said he had done, and that was the 2% and my a/f at wide open throttle has gone up from the low 10's to 10.6-10.8ish
i wanna try and achieve higher a/f

Alrite, today i thought i would do some more runs in my car and I GOT FUEL CUT , it happen at around 4500rpm at wide open
the only thing that logged this was my wideband and i havent had a chance to look at it yet, but from what i think i need to pull more fuel out in the higher end
ill pull my wideband right now and see

 

[Finkle]

Tha data i have is all messed up, so imma have to try again and get some fuel cut, to see whats really happening
i hope its not the fuel pump maxing out

The standback, at a MINIMUM, should be able to log the stock wideband. It just lame that it doesn't. We shouldn't need to purchase a separate WB when our cars already have one. I hope they improve the logging capabilities in the next generation standbacks.

 

[Finkle]

From what the master mechanic tells me here, is that the factory 02, is a narrow band so theres really no point in monitoring it

 

[Finkle]

the damn white stuff is starting to fall here pretty hard, loks like this is my last day of driving this car for a bit
all tuning will be put off for a little while,
