Stock TB is closing after 7000rpm

Post by Malkolm666 » 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?

You're going too fast - it is a speed limiter which starts at about 220 kph and closes the throttle to limit to 240 kph. We'll disable it for the next release.

Okey, thanks. Im gonna dyno next time on a lower gear.

Do you have a time frame for next release? A couple of weeks? A month? More?

I found the speed limiter, its under Speed Cut in "rev Limits". But that was set to 328kph, why is it slowing done the TB at 217-220kph? A bug?

No, there are two speed limiters. One rev limits, the other closed the throttle body.
