hey guys. I have a quick question for you. I have a buddy that has a greddy kit on an 06 S2K. I am helping him with an issue and want to log his runs and see what is going on.

for reading map sensor on the flashpro, do you read it in "PSI" or "/psi

PSI = when at idle it shows 4.11 psi

/psi = -21.0 "/psi

I know when you are idling, you are in vaccuum which is negative vaccuum. How come it shows 4.11 psi when I select PSI in "Sensor" setting? and -21.0 "/psi. -21.0 psi is a lot of vacuum??


After logging his car, I went home and saw the values in "Setting". When I logged his car, my setting include:

Vacuum and Pressure Units = Millibar
Pressure Unit = PSI
Vacuum Unit Base = Absolute
Pressure Unit Base = Atmospheric

I'm not sure if those setting has anything to do with it. What is the correct way to read the pressure goign through the map sensor.

If I set it to mbar in "Sensor" setting, the max reading would go to 1030 mbar? I'm sure that isn't correct or does that mean that its maxing out the map sensor?

any input is much appreciated. Thank you

 

also when we did a 3rd gear pull at WOT, the flashpro is showing

Gear 3 and then to gear 2 (in 4900-7100) to gear 1 (near readling)
which is really odd. A lot of weird thing.

I'm wondering if that has to do with the greddy emanager communicating with the ecu?

The IGN on the 3rd gear pull from 2800 RPM to 8000 is really strange as well.

I see timing from 0 degree at 2814 then to 15 degree at 4970. Then it drops down to 11 degree at 5924 and then up to 18 degree at 6887. Near readling its at 14 degree.

I know that boosting a car, you retard timing but doesn't that timing seem kind of low?

I know stock its in the mid to high 20s. Anyways just want to throw that out there...


let me know your thoughts on this. Thanks.

 

/psi. You should remove the greddy emanage if you want to use Flashpro

 

I'm just using the flashpro to log the car. I'm not using flashpro and emanager.

with /psi, the log shows .4 /psi which .4 psi is really no boost whatever.

Does that mean the turbo isn't making any positive pressure?

 

when i put up my N/A logs, it goes to -0.3 to -.6 which is okay because i'm N/A however with boost, it doesn't make sense that it shows .4?

 

i'm copying a post i placed in the forced induction forum. Can someone give me some input. I'm thinking the greddy emanager is screwing things up. If it was me, I would personally junk it and go flashpro

"I'm helping a buddy out with his car and the tune at the beginning was great. The first few runs was awesome until the ECU relearn and changes the tune drastically. That is what I think. However shouldn't Greddy adjust it accordingly?

The kit was installed and placed on the dyno with the base map. It showed great numbers. A/F was where its suppose to be.



however a few days later, the car started to act weird and power was falling on its face in the upper RPM near 5600 and up.

So yesterday I met up with him to do a few logs with the flashpro just to verify things. I notice a few things that was off. We did a 3rd gear pull from 3500 RPM or so.

1. The gear that the flashpro was showing was 3rd gear and then changing it to 2nd gear and finally to 1st gear in the upper RPM.

2. The VSS doesn't seem to be working so I am thinking the greddy harness is incorrect or something is wrong with it. It should be reading speed?

3. the MAP reading is pretty low at .4 psi in boost which is really really low.

4. Timing. Im not sure if this is correct or not. Having timing at 14 degree is pretty low. I know its boost and all but thats low to me. I know at peak torque you don't have too much timing.

5. The A/F took a noise dive around 6k which I think is caused by the VSS as it isn't engaging vtec. I'm not sure.

Here is the log graph:



My other question is, why did it run great one day and then a few days later its crap. I'm sure its something to do with the emanager...let me know your thoughts."

 

Did you ever figure this out? I just got back from the tuner and I'm seeing the same thing, the fuel just cuts out around 5500 for both 1st and 2nd gear. Also, the /psi barely goes into the positive range.

 

I need help with this also.... My mapp shows my boost BUT... at 5800 RPM's we have it set to 14* timing but only hitting 7* (no knock) at that same spot while live tuning. Also my fuel is cutting around that same spot. It will hold 11.5 all the way to about 5600 and the goes LEAN as hell. We have jacked up the high fuel BIG time but it still falls on its face. at the same spot and I cant get over 50% duty cycle on my injectors. WTF!!

 

Bad/knockoff fuel pump?
