Greddy E-manage for the MSP!

If you are planning on 20 psi and the z32 maf, you will want to add a map sensor.

The EM is only good for retarding 20 degrees, so you'll be right @ the limit. I'm not sure if you'll need to use the resistor with the larger MAF (try it without 1st)

You don't want to shut off the O2 voltage to the ECU from the sensor. (will trigger CEL) Good voltage clamps(such as FM's) limit the voltage the ECU sees @ the onset of boost.

If you want to just shut off the O2 @ a preset rpm, you could do that with the EM using the VTEC function to trigger a 12V relay, no need for the greddy modifier, but that really is not a good idea.

What size are your injectors?
SDS 2 injector?
 
Ok ive read this now about 3 times and have some questions. The ignition harness, i found the wiring instructions but no instructions on how to put the plug together.

Also you said that you can use the extra wires to make up the pressure harness, but never said how.

And whats the benefit of running the pressure module. Do i need it? I thought i was getting it too, but I didnt. Do i need it?
 
NO you don't need the pressure harness.

But it gives you a lot better control of adding fuel with your injector maps.

Do you still need one?

I use a DIY version of a 2.5Bar sensor and made a harness from an old computer cable I had...(needs to be able to plug into the yellow port on the EM)
 
Ya, I'd like one and I'm all about DIY stuff. My whole turbo has been DIY. Care to share your idea? Has it been working good for you? Also do you have some maps you've been happy with? I've found some base maps but i believe they are from an MSP.
Also what mods are you running, injector size, fuel pump, size of turbo, boost, etc?
Thanks
Andrew

I believe I used pin 76, but let me double check tomorrow.

"Also what mods are you running, injector size, fuel pump, size of turbo, boost, etc?"

JGS log manifold, Mig & Tig Welded, T3 .42comp/.48turbine, internal wastegate, 2 1/2" D/P, to stock exhaust, stock injectors (plus 1 550cc 5th injector, but turns out don't need the extra fuel right now) 7psi, non- intercooled, Bosch BOV, Emanage w/ 2.5 bar map sensor, Autotune running off a ZT2 WBO2, DIY O2 clamp, Removed 1st cat, 1st O2 sensor placed after turbo in DP, 2nd O2 sensor relocated behind 2nd cat (no cel), WBO2 placed in D/P under oil pan. Return line SS -10AN -welded into oil pan (another story) (used grey permatex for oilpan) Also had to flip the T-stat housing and reroute lower rad hose, used 1" copper pipe and 4 90 elbows.

Pretty much just an average stock '03 P5 ES w/ leather, sunroof& 6disc...
 
Thats almost scary how much our kits are alike. even down to the copper tube and flipped thermo housing. Only diff is i'm at 12 psi, intercooled and running a modified DSM garrett T25. All with a begi and a VC clamp.

Couple of things:
1. can you tell me where you got the autotune? I've heard of it but cannot find it.

2.I really need a serial number for the emanage software. I looked all through the box and cannot find one.

3. Did you have some maps you'd care to share? I found one base but its for a MSP so i'm not to sure about using it

4. Do you know what the magic number on how much to retard your timing for every pound of boost is? I used to have that info but cannot find it in all of my saved turbo info.

Thanks man!
 
Are you running 12psi on stock internals?

I am curious as to how high is safe, (aside from proper tuning) from what I've read 9psi seems to be the max on the safe side.

There is no magic number to retard boost, BUT 2 degrees per pound of boost is very safe, I retard between .75 -1 degress per pound of boost(because non-I/C). with an I/C it should be less. @ 6psi intercooled it might not require any retard****. What are you using now for timing control?
Sounds like you should start with .75 degress per pound of boost.

I have an I/C, But - My goal was low boost(less than 8), DD, and throttle responsiveness, that's my lazy man excuse...

****Assuming normal P5 ECU and not MSP,MP3, ect..

Better Pm me w/ a real address like .yahoo.com , I can't add them here because it's a .GSC file....

Are you running 12psi on stock internals? yes, for now

I am curious as to how high is safe, (aside from proper tuning) from what I've read 9psi seems to be the max on the safe side. thats what I heard too, so i went slowly up to 12. Been there for almost a year now

What are you using now for timing control? nothing, only tuning i had previous to getting this emanage in was a begi and a VC
