CPE EMS Problem???

[laloosh]

did u always have these issues? Or did they just appear. What exactly are the issues cause i must have missed the thread/post

 

[knowledge007]

What do you mean always? With the standback or before? Before the standback I had no issues. Only with the standback. Basically the issues never caused anything in particular, just what Finkle is getting the low circuit inputs and random multiple cylinder misfires. I just didn't like that fact that that ******* CEL was on. Other than that the car ran great, all data logging was correct...

 

[laloosh]

what are the issues u are having with the standback?

 

[knowledge007]

Um, what I said in post 33 and 42. The only real issue was that 3 to 5 second delay I had to wait before I cranked. But still got the CEL's... At the moment I have removed the standback. Going to wait for the PNP connectors.

 

[Finkle]

If i wait the 3-5 seconds i have NO CEL's at all, i dunno maybe mine being a canadian model or being right a sea level is making a difference
i dunno im stumped but im still running it at 15psi with no problems imma try 17psi in abit and see how it goes

my boy just installed mine at first he had the same problem w/ the red and orange wire reading 4.9 or 5 volts and going back to .2 after a lil bit....so we started it and it fired right up i have it running at 17 pounds and it feels fast as hell....

i finially got some runs in last nite, my frinds family owns a ton of property with a 3mi long road at one end of the property. Well i have no problems with the car at all, on either 15 or 17psi, but as soon as i hit wide open throttle in 4th gear, the car would hiccup and backfire at about 4500rpm
now i beleive that has something to do with those wires not reading the right voltage

nope...nothing with the wires. Its something with these cars with cold weather. My car did this before the ems with a aftermarket bpv. with the stocker it doesnt do it.

 

[Finkle]

it only does this with the cp-e plugged in, i dont understand, the only thing i can do is wait for the wideband which has been elayed till monday
i hope everyone at cp-e is back monday

 

[laloosh]

it does it cause ure running/holding more boost. Nothing with the cpe unit is flawed. My car started doing this with i/tbe/bpv. At around 4500 you feel it slowing down and then it stutters, as if the car misfires, then comes back alive, then stutters ever 300rpm or so.

 

[Finkle]

yes, now why is it doing that?
thats not normal

 

[laloosh]

if u figure it out let me know.
My guess is the fuel pump/maf sensor being maxed out with cold weather.

 

[knowledge007]

Never had that problem before??? My car runs like hell. Although I do get an occasional backfire when switch fast. Even withouth the ems I still get back fires but no hiccups just huals ass...

 

[laloosh]

for me this only happens in cold weather and with the forge bpv on.

 

[Finkle]

im started to get get quite disappointed with this ems
but hopefully a tune will fix this, but if the maf is maxed out then im s*** outta luck
now i really wanna get a hole of cpe

 

[laloosh]

yea i was disappointed with the base maps lol. ITs a 2 psi boost and everybody says its god. Like i said i dont see myself gaining any serious power with tunning like people here think. All the gain will be from boost, and then u run out of fuel...the end.

 

[knowledge007]

Keep me posted Finkle as I have already taken the ems out but would like to know what Jordan has to say. Anyhow, I will be waiting for the PNP connectors as I have already soldered everything back to its original state.

 

[Finkle]

im almost ready to solder everything back, i dont understand how the pnp will be any better, its gonna be a base tune as well, and you wont be able to alter the tune. If im running outta fuel or even experiencing fuel cut what makes me think that the pnp will be any better.
I just tried calling p-e looks like they wont be in till monday either way

 

[knowledge007]

Remember Finkle you have to tune the car at a tuner of your choice. I primarily picked it up for the boost and thats about it. I have everything else from CP-E except the FMIC. I was going to get the tune done sometime in the next century, but hey what the hell. I know what you mean by the PNP but at least I won't be cutting anything anymore. I don't and will never do that again. I will always wait for PNP.

 

[Finkle]

yea thats tru, so what did u do with ems knowledge? its not just a paperweight is it?
