I am running the tephramod v7 speed density and I got the gm air temp sensor installed and am logging it using evoscan . But my question is how do I log kpa . Which value should I select to log in evoscan for KPA. Btw I am also using the omnipower 4 bar map sensor.

I have already got the idle down pretty good with only +2 thru -2 short term fuel trim and sitting at 14.6-15.2 at idle , The car drive pretty good on speed density but WOT is no good it goes way lean , I need to figure out which KPA values I should be adjusting that is why I need to know which value to log.

 

Post a picture of your VE table and map calibration table.

I'm thinking because your really running a 2.4L you will need to boost the Load points on the right hand side of the calibration table up by 10% to compensate for the larger airflow.

 

here is my settings so far keep in mind I only tuned 0-2500 or so...

 

lol damn thats alot of VE.

Ok what i want you to do in the SD Map sensor calibration table is highlight the right column and hit the "*" key to multiply the values by 1.2 which is 20%. This should give us the rough estimate of the load required.

Make sure you have the table set to the proper map scaling too it will be useless if its set to the JDM 3 bar map sensor scaling.

Once thats done bring your VE table to the normal levels:
89.8438
92.9688
94.5312
95.3125
95.3125
96.875
100

96.875

You were right made those adjustments and it drive fairly well now ... Idle now sits 14.9-15.2 , cold startup is clean ... Now to address wot tuning , which table should I edit to make fuel changes , wide open throttle right now is 10.2-10.5 which is a little on the rich side considering im non turbo and all. Also I need to address 30% throttle I get a leaning out issue if i give it 1/4 throttle or so but if i floor it the lean out goes away.... Thanks for you help so far... Also how do i log kpa or do i just log load and convert it to kpa?

 

Ah the throttle tip in is the problem right?

Adjust the accel enrichment vs rpm. I know there is a minimum load table for the accel enrichment but i've been too lazy to mess with it.

If your going super rich on WOT and don't want to adjust your fuel maps you can adjust the high load points of the map cilbration table. Specifically the load points at 100kpa and beyond. Make the load lower and it will provide less fuel that simple.

Edit:
Oh i forgot but logging kPa requires you change the equation for logging boost through the sensor which is MUT 38 i believe, can't really tell on my desktop. You should be able to find a 4 bar kPa xml portion to get your started in the speed density thread.

 

youre running a 4g64 engine?

This is what I ended up with in my 4g64 Galant.
