CPE EMS Problem???

[Powerslave]

i sure did miss good old 17 psi map plus holding boos past 6,000 is reeeeeally cool. now i just need to get it tuned.

man i need new tires i have al most no traction in first or second when i floor it, this thing rippes tarmac at 17psi!!!(drinks)(10)(drive)

Yeah the CPE Standback is awesome! I got mine running off of a basically stock map and one tuned to hold 19psi with a 12:1 ratio. It pulls so much harder than before, I love it! I had a CEL come up due to it running lean at idle but it was easily adjusted by my tuner. Jordan from CPE just gave him some great instructions on bumping up the MAF voltage up 1% and so far its perfect. It never ran rough or with any problems but I just didn't want the CEL on for dealer visits.

the tuning shop i want to go to has a 2 months waiting list, so right now its tuned to what i think is good lol, my air fuel hovers around 14 at idle and while driving anywhere from 13-14.6 i was gonna make it a bit more rich but oh well......15psi is good enough for me right now, gonna try and tune 18psi as soon as the weather holds up

What are you running A/F at wide open throttle tho. Over a certain tps angle the computer says screw emmisions I want power and then you should be more like 10:1-12:1.

yeah I had the same cel too lean at ilde its cuase the cold wheather its no big deal and they have quick fix mine is gone. Car was running perfect even when it was on. I can't wait to get mine tuned!

Its Started snowing here, looks like imma have to put the car away for the winter.....the tune will come EARLY SPRING with maybe a new mainfold

 

[Powerslave]

that sucks about the snow although it is nice for christmas and stuff, yeah 4whd is a advantage for the evo and sti. But they also cost alot more for around the same performance and power save the awd. Plus the ms3 has a nicer interior. I'm getting a tune as soon as i save some money, no snow down here.

 

[Craighjr]

I got the snow this morning as well but it should be 50 and 60 the next two days. Im still torn on tuning this year or not. I have a check engine lamp for a lean code either off idle or at idle. The standback can only use the maf xf to fix that so that will throw off the tune once its done I imagine. I may just tune it this week anyway as I'm bored as hell not working. Hopefully Jordan will e-mail me back with a few solutions or something.

dude I got the same thing "too lean at idle" code its no big deal, the cold weather just throwes the fuel trims just outside the acceptable range with the standback. Jordan has a simple e-mail map fix that add a touch mor fuel at idle or I think you can slightly increase the maf voltage. It doesn't hurt the car mine went off byitself.

"no big deal" but mine will not go away. The ms intake and stanback both lean the mixture out so I'm still waiting on a fix to work.

 

[Powerslave]

you could just get thier intake, I know 300 bucks though kinda sucks

I upped the scalar on the maf xf to 2 around idle to hopefully fix the P2187. Then I sloped it down from 1.5 to .50 from the off idle to 3.9 volts to keep the P2177 from coming back. If this doesn't work I will put on the stock air box for testing sake. I have thought of switching to a CP-E intake if necessary.

 

[Finkle]

well looks like imma have to def. put the tune off for the time being
i WANT that manifold

 

[sp33d 3]

does anyone know how to get rid of the cel P0102? i'm switching to the cp-e cai this weekend but i doubt that will change anything... i've been running the bypass because the chip has violent fuel cut at 3000rpm and 4500rpm

and finkle are you from the gta by any chance?

 

[Finkle]

No im not from gta

i had that very code as well. What mods do u have?
check to see if the mass air flow is plugged in, if it is plugged in
u can pull it out and clean it with a q-tip ( it may be dirty)

are u running a standback??

 

[sp33d 3]

i have the cp-e full turbo back system, mazdaspeed cai, forge bov and im running the bypass plug because of the fuelcut when the standback is connected... i've already tuned it, paid 7bills(so pretty much 1400 in total) for it yet it didnt resolve any of the problems... i'll have to check about the mass air flow though, but will this reduce the fuel cut? i've been on the phone with jordan and he has given instructions to reduce it but not get rid of it completely

well that officially sucks. Tell you what, put ure stock bpv on and ure fuel cut will go away.

 

[knowledge007]

I never have experienced fuel cut...???

 

[laloosh]

move to a place thats cold.
