When I get to the shop I will do that..

 

It would know where it is in the 0% column by the RPM point. If you have a range of RPM and only one column, you will ONLY have one point for every RPM point... thus, why would you need the TPS?!?!?

Fuel tuning in the 0% column is done “piggyback style” using injector scaling and MAF voltage offset. Tuning of the 0% column is done mainly by using
the Injector Flow parameter value settings in the Open Loop Fuelling parameters menu. Based of the aforementioned, any changes applied on the 0% column and at a certain RPM point would apply across the board on the same RPM point on the stock ECU fuel map regardless of the MAF point of the stock ECU.

 

And what do you think tells the MAF and the Trottle body how much to open and what background map to run on the stock ECU, which controls the car in the 0% load column. Im telling you the UTEC needs some input of the TPS regardless open loop or closed loop..If you wish to debate with me based on your vast tuning experience then do so via PM and stop hijacking this thread with debate.

 

Don’t take it personal man I’m not doubting your tuning abilities. And I’m not here to hijack this thread It would be nice of you to teach us a thing or two about tuning and how does the TPS controls the MAF sensor; it might be beneficial to all, but if you wish otherwise, so be it.

i made the changes to the TPS Min Voltage and TPS threshold for Mapping as you said. Set the injector scaling to 380 / 380 and modified the %0 column not to bog the car but this didn't help. The car bogged and died. I wasn't able to run it again for half an hour (prolly the plugs were wet with fuel).

BTW thanks for all the inputs guys!

Julian,

I've sent u a pm on another issue.

 

did you use a bunch of negative whole values in the 0% column? Lets see what you have.

 

i didn't bring the laptop home but the %0 column is full of negative values which starts from -8 and decreases.

 

it would be great to hear how to calibrate those numbers into UTEC. also it's weird that this info is not included in the manual!!

 

The MAP numbers or the 0% column?
There are instructions for the map sensor in the manual IIRC and the 0% column is explained...you have to road or dyno tune the column to your target a/f. It works a slightly different from the other columns because it is piggyback style values whereas the others are injector time values.

 

well i am putting a fully built TT motor in my car this weekend and switching it from the EU that runs it now in the G to my UTEC. i hope i dont have any problems, but if i do, i know where to look!!

 

No i'm talkin about how to calibrate MAP sensor using the "values" that are given on the calibration paper of the MAP sensor.

 

people are having a few problems with UTEC but still I think that it is a strong EM.

 

You would need the attached excel sheet, where you input the numbers in and it will give you the numbers that you can use with the UTEC.

It calculates 112 / 169 I'll see if these numbers will work.

Thanks a lot man.

 

I've entered the numbers as 112 / 169 and the UTEC is reading the MAP wrong! It reads - 12.5 psi @ idle which is actually around 8.5 psi.

 

Dude, if your getting 8.5 psi of boost at idle you got bigger issues...

 

LOL

it should be -8.5 psi for sure

 

Actually vacume on my car reads -15 to -20 at idle...

 

psi ?

 

-15 to -20Hg's of vac at idle is normal for our cars.
