t509 maps

[OlaWendelin]

Hi!

Anyone know why te only differense between Tune ECU hex files for:
9852 - T509 885cc Speed Triple (up to 1999 model year) with standard exhaust
9853 - same but low aftermarket silencer and
9854 - same but high

are the values in AF/1?

Values in F maps are the same, values in I maps too.

The ECU do not have O2 sensor so how does it know how to get 13.5 or 14.75 in AFR according to the AF/1 table?

Looking at MAPS for the early daytona shows changes in both F, I and AF/1 maps.

In other words: I thougt it was the F-values that were to be changed- does it look the same in the tuneboy world?

I´ll answer my self, i downloaded tuneboy and loaded the .bin-files for t509 and what I can see both F, I and AF/1 maps differ between the three different available tunes for t509.

I guess I´ll have to manually change the 9853.hex to values shown in the 9853.bin file to have some real mapping done.

Tidy but doable as has been said.

Well, I have been out testing and indeed the change in AF/1 do make differens.
Having had my bike in for service at an official dealer, who downloaded a 9852 map from Triumph the bike didn´t behave pleasantly, I downloaded the 9852 map fron TuneECU with the only difference being in the AF/1 tables, the bike behaved alot more pleasant, I do miss a litle bit of power up in revs in high gear, but not a big issue.

I dont know whats is right or wrong here but the TuneBoys 9852 map differes both in F, I and AF71 from both TuneECU and the map downloaded by the Triumph dealer, obviously there are different versions out there.

The bike was today with K&N and original silencer.

Im having an issue with cold start, It won´t start and just run, i'll have to put on some throttle by hand for the first minutes of running, even though I have calibrated the TPS. TPS voltage reading in tuneECU were 0.53V. I dont know About these old Sagems do they need to be 0.6-0.62V to work?

I did changes in AF/1 table only leaning a bit in cruise to get some more decent fuelmilage and leaned a bit in very low rpm and loads. This helped with the starting, but now it starts and after 15-20 sec it boggs out with too much fuel.
If i were to be thinking the megasquirt way this would be an after start enrichment issue- in the sagem world that is a non existing term and thus are not adjustable.
I´m going to keep changing the AFR to see if it changes.
Right now after start It seems like the engine goes so rich that the airvalve can not operate the engine at desired rpm, according to rpm table.
