450 FSE 2004 starting issues

[Yngvim]

We're you able to set the TPS in ECU before you made the changes or after?
+170mV means less air less fuel and I think it will affect the timing as well

I made changes to CO-trim before and after i made changes to TPS.
When i had +290mV then i tried changing the CO-trim from +10 to +30 (Originally i had +22). I rode some time with +17 trim and had no problems (maybe only that engine got little bit too hot sometimes).
At the moment i have +170mV(+20 trim) and it rode very good, it had more torque (i got the front wheel off the ground much easily than before). But still the issue that it started to stall little bit too easily and very quick snap on the throttle sometimes stalls it too...higer idle should fix that in my opinion. I set the CO trim to +25 now and hope to test it out tomorrow.
But yeah i should say that +170mV gives more torque but with +290mV engine revd little bit quicker?(at least when listening with ear).
So i'm confused at the moment...i like the low end torque but if that(+170mV) gives too lean mixture then thats not so good either.
I checked the TPS with guzzydiag, and didn't see any dead spots (turned the throttle really slow and watched the TPS angle and voltage).
What else should i check? Replace injector?

Hello, good, I'm new here but with old problems my name is victor and I'm from Girona I have a 2006 fse and it's giving me a bag I had a 2006 map and from one day to the next it didn't want to go anymore I opened the engine I put piston rings and everything his and nothing managed to go wrong but well I did not change 4 tps I have put as they say from zero to 290 reset and it drops to 4.74 and 63 in the 2 maps and with the 4 tps I have changed the map I have mounted the 2007 and exactly the same to 2006 it does the same to me any idea?

I'm not shoure if it is running lean , wrong timing can cause the engine to run to hot, but you can try any voltage between 170mV and 290mV and find the sweet spot. The lower value is 4.5° opening on the throttle. It doesn't hurt to use injector cleaner.
Hope you will finde the setting you like

Just to be sure...every time when i adjust TPS, I should reset TPS also?!
Will try to play with the CO trim few days.
Still it's very strange that this stalling started in the middle of the ride....

It should be set at 290mV. All the parameters in the ecu are written according to that. It seems like TPS reset didn't work when you adjusted the throttle body first time and you are compensating for that by changing the TPS value. It should be set at 290mV after that you can make adjustments without TPS reset

Hmm...okay. Will try that. At the moment i have always made TPS reset.

I have not been able to use guzzidiag to set the TPS.

Maybe we're doing it wrong.

Here is a link to some help

When i have played with TPS then GuzziDiag shows XX.XX value for TPS angle...when i reset it then it resets it to 6.37 degrees. So i assume that resets the TPS correctly....
