calling all K-Pro masters!!!

[skoolnu]

well i got a hell of a problem with my k-pro. the map sensor isnt reading boost, and my logs show my a/f locked at 10.70 only. but when i did my logs, the a/f seemed to work. anyone have any idea.

are you throwing any codes? check and make sure your MAP Sensor is connected?

if there is anything that you can think of that you think will help: what calibration you are using, mods, etc. post up.

[jimmyjames]

when are you seeing this?
(I.E. when connected to the ecu and monitoring the operation? during a datalog?)
If I were you, i'd check for updates first and then reload the calibration and see if it changes.

If you don't smell a ridiculous amount of gas out the muffler then I can tell you the primary 02 is probably bad. Mine was doing that before it went out. It would work fine till it really got warmed up and then it would go top out rich @ 10.7. Double check your map sensor is plugged up correctly and that you don't have the tps and map sensor switched on accident. I also second what jimmy james said on the updates.

[skoolnu]

not throwing any codes. MAP is plugged in, and mounted fine. stock MAP. JRSC w/ 3.8", 650RC's, intake, buddy club race header, k-pro.

Im new to k-pro and tuning in general, so bare with me. the person tuning the car for me informed me about this after i sent him some datalogs.

when connected to the ecu and monitoring the operation, the map will not read boost. the a/f is reading while doing this... same when i did a datalog. wont read boost, and the display is reading a/f... but i guess the recording tells another story

[dustyboner]

you need to go to parameters/closed loop and uncheck "disable p1167" and "disable p0134"

and if your trying to tune the 20 low cam, you need need to set up the cam angle maps different (like in this .kal)

[skoolnu]

sweet. that worked for the a/f problem. thanks dustyboner. lol. that screen name is great! now i just gotta figure out this damn MAP sensor.

[dustyboner]

you should do another datalog cause your getting knock @ 0.1psi (4.6 sec) probably need more fuel there.

[skoolnu]

any idea why the MAP wont read any boost level?

[dustyboner]

did you hook up the map sensor right ? it sounds like your map sensor is getting its vac/boost signal from before the supercharger.

[skoolnu]

yup. car has been supercharged for a year now.. never a problem. I just went from the street kit to a custom race kit. just finished installing everything this week. ran a few logs last night for my tuner, and we find these probs.

the display reads the MAP sensor, just when you get into boost... nothin, floats around -.01 -.04. Think the sensor took a dump?

[talonXracer]

In your cal, you have the primary A/F sensor turned off, any reason why?

also you have no correction factors for gear or temp, that can cause some issues.

[skoolnu]

its a base map that was sent to me to run a datalog with. the car is far from tuned.

[Iluvcars]

you should do another datalog cause your getting knock @ 0.1psi (4.6 sec) probably need more fuel there.

If the map sensor is not reading correctly, then making tuning adjustments to the wrong columns will be incorrect. Also, he's doing WOT tuning, so for boost, only 20 degrees has to be locked in the boost columns.
If part throttle would be done (and i have not seen 20 degrees benefit for anything, 30-40 has worked for most k series in part throttle), so pretty much stock hondata maps at part throttle for cam timing is set. It is only ignition and af that has to be modified. You change cam angles only for WOT performance.

Also, gear and temperature compensation are done after a full tune is completed, and since he mentioned base map, you cannot make those changes until the full composite map is finished.Just thought i'd let you know.

[skoolnu]

any other ideas on why the MAP wont read boost? this is driving me nuts!
