CPE EMS Problem???

[laloosh]

i should not be experiencing fuel cut. In the boost settings, under advance boost your boost clip is set to 13 psi. Meaning your map only sees 13psi.
Do you have a aftermarket bpv? CAuse mine did this before and after the standback. I put the stock valve back on and all my problems went away. Theres dones of poeple complaining about the stutter/backfire issues at high rpms in the cold weather.

 

[Finkle]

stock bpv, i think the cold weather may have a lot to do with it, but hopefully i will be able to see everything when data loggin, and with the wideband
i dont even wanna try 17psi yet without my wideband

 

[knowledge007]

Don't be scared I ran 17 with no problem. The data logging is cool as s***... I basically bought the EMS just change boost as I please...

 

[Craighjr]

yea my wideband is coming in tonite and should be in 2morrow
To anyone who wants to kno here are my volt measurments
Pin # Wire Colour Expected Measurment Measument
1 gray 10-14 volts 11.93
5 white/black stripe .61/.80 volts .61
6 white/brown stripe 0.5-4 volts 2.11
8 orange apprx .2 volts .3
now the problem im having with this wire pin 8
sometimes it will read about 4.9 volts and then sometimes it will read .3, ive checked the connection several times, nothin wrong at all
10 red 10-14.5 volts 12.3
11 green apprx .2 volts .3
same problem with this one pin11, it goes to 4.9 when pin8 is not reading right
but when one is reading right they both are
13 white 1.1 volts .96
14 yellow 1.87 1.91
15 red/white stripe .61 .62
16 blue 1.87 1.91
17 orange/red stripe .5-4volts 1.91
20 black/brown stripe .2 .32
pin 20 is purple tho typo in the instructions?????

what u guys think that HAVE an cp-e ems

Exact same here. I talked to Jordan about some unrelated celo issues. The 5v on those wires I never checked into. Pin 20 is puple though the chart says onterwise, pins 18 and 19 are unused and the brown wire isn't connected either.

 

[Finkle]

yea thats where i was, i gotta talk to jordan myself, and see what he says about the 5volts i wonder why the car is doin that.
maybe thats whats causing my backfire.......
should i try and go to 17psi or just leave it till i talk to jordan

 

[x'ed]

Just a thought, maybe it's different pin set up on the mazdaspeed 6 and the standback was designed for that. I don't have any idea, just a shot in the dark.

No the speed 6 has a 100% different pcm. I would run 15 till jordan gets back to you. I didn't even install the switch for 17 in mine yet. Figured no reason to tempt it while untuned. I am having lean codes 2177 or 2187. I am vta but the bov should make it rich??? I may go back to recirculate and 0 maf correction to see what the hell is up. I am a few hours away from CP-E but they don't tune cars. I was mega bummed about that. I am going to talk to them and see who the recommend to tune their stuff.

 

[Finkle]

i have a cel light but i think its for the cat not being in, well thats what it was before the ems install....i go in saturday to find out exactly what the cel light is about, hopefully its all o2 sensors

your lean codes are caused by ure vta. Let me know when ure going to get tunning done. Im from jersey as well, we should go together.

 

[Finkle]

got my codes puleed and came up with
P0139 - which is my rear o2 sensor (o well)
P0107 - map sensor circuit low input
P0245 - boost soliniod

the tech thinks that the last 2 codes arew from the car starting up without the ems loading up, so far ive been lettin the car sit in the on position for 5 secs b4 starting and no cel's for me

One one-thousand, two one-thousand, three one-thousand, four one-thousand, five one-thousand. You know, I don't think I'm always gonna have time for that in the heat of a given moment. I hope CP-E comes up with a fix.

 

[Craighjr]

I don't know about that. The standback works fine for me when I just fire it right up. Maybe try to go back to stockish to figure it out. Does your car run well with the bypass plug on? Mine runs fine then, but pulls lean codes with the standback hooked up, VTA and a MS CAI.

Thats funny, I was getting a the po107, p0102 low circuit inputs. Also got a p0300 - random cylinder misfires detected. If your getting the same then it is the standback. Now I feel like an idiot for taking it out... Kept insisting that I cut a wrong wire but I checked over a 100 times and everything is correct. I see now what you are talking about Finkle about the typo. Yes pin 20 is purple. Let me know what you Jordan has to say about your problem Please!!!

Another thing, I crimped and you soldered and your getting the same issues...

I ran the bypass with my setup for quite some time and had no issues. Thats why I am so bummed. Only had issues with the standback installed.

 

[laloosh]

mine runs fine...i dont need to wait 5 seconds, i just jump in and fire it up.

 

[knowledge007]

With the bypass, it would crank right up with no problem... Did you uninstall the fuel cut defender for the EMS?

 

[laloosh]

yea the fcd and mbc are sold

 

[knowledge007]

Thats what I thought. Was just glancing at your sig...

 

[laloosh]

Yea sorry about that. My sig is updated now. My ems runs fine, doesnt take a while to start up, no cels, no wierd issues. Just 17psi of pleasure lol. I didnt solder anything in, i just twisted all the wires exactly how cpe described in the how to.

 

[knowledge007]

Thats ****** up man, now I am really bummed... I miss you 17 psi so much. I don't understand why some have these issues and then some don't. What gives?
