Stock TB is closing after 7000rpm
Posted: Mon Oct 09, 2017 3:31 pm
Hi, I have a -04 CL9 with TSX 07 ecu, and flashpro. Have driven it with flashpro for over a year now. With the stock engine It never was never any problem(I attache a log from the dyno "rsp_231hk"). I have no CELs. Everything else works great.
Now I have built engine with higher comp and DC stage4 cams. And also you have updated the flashpro 2 times in september.
There is a problem with the DBW now, the ThrottleBody starts to close after 7000rpms, same stock TB, I used the same calibration, just changed fuel, ignition, VTC and vtec in it. Max power is at 7150rpm when TPlate is 89% and falling like a rock. This engine should get the peak at 7800-8300rpm. So I miss at least 1000rpm.
I have read all the posts on this forum about DBW problems, I know the different on the 2 different DBW-systems, I know all about that a larger TB can make alot of problems, I have read the flashpro help Content so many times now. Have tried to change so many things in the calibration. Have reset ecu. Have done idle learn procedur, I have also read the TSX CL9 WSM about Thottle body, the relay, the modul, the TB, the cruise modul etc etc..
The only electrical thing that Ive changed is that I updated the Flashpro software twice. nothing else.
Then I also have a question,"Target Throttle Plate" table, can you please add 7500rpm and 8000rpm into it? Please?
