GReddy Profec e-01 wiring question


Jake

Recommended Posts

I'm fitting a GReddy Profec e-01

 

I've wired the power lead into the clock. Red wire going to the clock's Blue/Red wire and I've connected the black wire to the clock's White/Black wire. All right so far?

 

What should I connect the Profec's yellow wire to? It just says this wire is "Option" in the manual, I've no idea what that means. Optional maybe? What does it do?

 

I believe the brown wire goes to the ECU for reading the revs but I don't know which wire it connects to. Anyone know?

 

Thanks

Pin 58 on the B1 connector

or pin 16 on the A1 connector

or straight off the back of the tach?

Straight off the back of the rev counter might be better/easier than hacking the loom about. Anyone know which colour rev counter wire I'd need to connect the brown PRofec wire to?

 

Thanks

Well I got it all in and working last night (apart from the rev counter wire) and been having a bit of play with it today.

Makes quite a difference doesn't it! :eek:

The power from 3000rpm onwards is much stronger than before. Also, my car never used to make full boost until about 4300rpm but now it's flying from 4000 on.

Well, I couldn't get the auto thing to work. Doing full throttle runs and looking at the PRofec didn't seem very sensible. I tried to do it but chickened out at 1??mph.

I saw a post of yours that said to use manual mode instead so I used that today. I took a guess and put it on 90% and 35% gain with a 1 bar start. This was waaay too much boost. I saw 1.51 bar at one point :eek:

The thing is, my car boosted much too high anyway so I guess the PRofec can't help with that. I'll have to put the restrictor ring back in to lower the peak boost and start from there. I'm hoping that it won't lose me power from lower down the rev range, I really like the way it is at the moment.

 

Do you have any suggestions for a manual settings starting point?

Well, my restrictor ring keeps boost at about 1BAR without the controller now. I have:

 

set 57

gain 35

start 0.9BAR

 

If you go to the warning option under setup, you can put a boost level at which it will automatically reduce the duty cycle of the control valve and how much to reduce it by. I've got mine on 1.3BAR and -100% at the mo, so when boost gets to 1.3BAR it immediately turns the valve off completely until it drops below that. Seems to hold at 1.3BAR very consistantly, although I will probably change the -100 to a smaller value.

 

The other thing you can do is start the logging going and go for a run. Then you can step through all the stuff it measures afterwards to watch what the boost and valve duty cycle is doing and tweak the settings.

Thanks for that Simon, very helpful.

 

Do you know how to reset the stored peak boost value? I can't see an option to reset it.

 

Aha yes, took me ages to find that one. When you're in dislpay mode (i.e. looking at the graph or gauge view or whatever), hold the up button for 2 seconds. That resets all the peak values.

 

Took me a while to figure out the record and replay too. To record you press the down button, it should say "rec" at the top. Then you press down again to stop recording - it should beep. To play back you press the set button , i.e. the middle of the knob (ooerrr mrs!) for 2 seconds. Then you can press it again to pause, and turn it to go back and forwards. You press it again for 2 secs to go back to normal mode.

 

Although it only displays three things at once, it records the whole lot, so you can select another 3 things to look at and replay it again.

Three things? I've only got one thing to look at : Boost :D

 

I can't get the revs to display. I connected the brown wire to the back of the rev counter like Matt said but on the Profec it's still showing 0 rpm.

 

 

Thanks for the reset/record/playback tips - saved me ages of frustration. :thumbs:

Bugger. That isn't working either. It beeps but doesn't clear the little peak boost pointer.

Ah! Never mind. According to the manual it's not the peak boost pointer it's the warning point. Sorry.

 

 

Still can't get the revs to work though :(
