I am trying to tune my car
Its an Evo 5 with an evo 7 Ecu and I am running a SD 96533706 Evo 8 tephra mode.
I put an Omni 4bar but for an Supra since Evo 5 manifolds do not have a hole for the map sensor.
I tried the normal settings for the Map vs Ve but it doesn't work.(the map preferences is set for Omni 4 bar)
The car is currently on a Mustang dyno and I redid the calibration .The values up to 0.4 bar are correct. I set it up using a boost gauge.Every 0.1 bar is 10 load.
Look how weird is the map. Why is that?

 

That map is set very strange. What size injectors and what size motor? I am not familiar with that version ROM but I can look I suppose.

 

The car is a 2.0liter with stock evo 8 injectors.
What i do not understand is why i am so off from the readings of the omni map sensor....

 

I end up with this calibration.



I messure the voltage of the map sensor and they look ok.

Kpa Volts
20 0.13
40 0.35
60 0.59
100 1.16
140 1.67
160 1.92
200 2.42
220 2.66
240 2.9
260 3.16
280 3.4
300 3.65
340 4.15
380 4.57
400 4.82
420 4.95

Now the load up-top looks ok but the load in vaccum is not exact.
To me it seems that there is an issue with the definition itself . Maybe the map (mapvsload) is slightly offset?

here is the def



I am using a 96533706-tephramod-l2r99gst-dma-sd.bin file

 

I have found on the stock injector SD stuff that I have had to rescale the injectors from the factory 513 value to 542 and in one case 562 in order to get it to idle and drive correctly with my other SD settings. In so doing the fuel map values lined up though and an 11.5 was an 11.5, least in my test case.
