Tom, I can help you set this up. This is how I run my logging for my PLX SM-AFR wideband controller. It's connected to the rear ECU pin. Works extremely well!

 

im not sure if i have or not. i know i had to set mut values before for customers when they wanted to use rear o2 to log through. is that the same ordeal?

Ok great. i still prefer to do actual logging via serial to usb though since its more precise. but i need the voltage ranges to set the failsafe up for sure.

 

Yes, same thing.

 

Still working on the tune. Tom is pretty busy as always. And eventually I'll need to throw a Walbro 450 in there so I can go over 500 whp.

Really happy with the car thus far, I want to see what it does on 91 though.

 

we gotta figure out what pump you want to use! so we aren't limited to 470whp or so.

either the 450 or maybe be a test pig on the new AEM e85 pump.

 

double walbro 255s thats what im running now 450/400 mustang dyno and tons of fuel to go around

 

Double pumper is on the way

 

So far I'm enjoying my EF 2.5 despite the fact my Hallman is excessively bleeding boost from 26psi down as low as 20psi up top . Switching out mbc tomorrow to rule out that I have a bad Hallman .

If all goes well after the test, I will throw in my Grimmspeed 3-port and car will be getting tuned tomorrow.

( Yes , I've done a boost-leak test and the WGA was adjusted before installing the turbo in myself. Ever since the last shop switched out my Hallmans inner spring to fight bad boost spike the mbc hasn't been working properly since)

 

3 port is a lot better... as you can say, holding boost up top is no problem for this turbo

Oh and I'm putting in my double pumper this week and having Tom tune the car... should be interesting

 

This thread will be revived when we post our numbers up lol , hopefully all works out for me today after work and I'll try to get a VD result up asap

 

Has anyone got any solid pump numbers on this turbo yet? I'm looking to upgrade to something and if I can squeeze out 450 on pump I'd be all over it.

 

Just got back from tuning . My bad boost taper was from indeed a faulty/bad Hallman mbc , don't ask how or why just is.

With the Grimmspeed 3-port in my car is holding rock solid 26psi and feels good on the VERY conservative timing ( 9* up top ) , my tuner tells me the car has alot left in it but for now I'll drive the car as is and get used to it.

I'll get the VDR of the car as is , but it's nothing impressive so to speak ( VD 360ish or so) . Spool-up is nice and very close to stock

 

On 91, I should make 400-410~ whp. On 93, I'd say 430-450 whp would be possible with the right mdos.


That's on 93, right? Push it up to 30 psi. Are you going to E85 at any time? This turbo is insane on E85.

 

Yes sir, 93 oct. . I do have access to E85 as a station has opened up down the street but I'm keeping it 93 for now .

Once I get around to getting the car re-tuned again with more timing I'll be set.

 

We shall see what we can get out on 93 here in about a month(or less).
