adaptive mapping question
Discussion
Hi,
I recently had a FFF2 head fitted to my Tuscan. I noticed that (even some time after a reset) some of the adaptives are quite high (30%+). Normally, that means that something is wrong. Throttle bodies were balanced and all HT leads seem to be ok. Could this be because of the additional power that is available from the FFF2 head (and simplex chain conversion)? I does sound logical that some additional fuel is needed compared to normal?
Any suggestions are welcome.
Regards,
Maurice.

have you set cam timing correctly, also ignition might need adjusting, if the cams have more lift and duration than standard it will need remapping.
Standard lift at the valve inlet and exhaust is .416 thou less tappet clearance and 268 duration, i would ring RG and ask for tech info on the set up hope this helps.

Maurice,
I have compared your readings to mine.. and with only a few exceptions have similar results.
See here
I understand my Sag to be std.. and too see table entires over 4000 rpm.
From the ECU diag s/w you can "Save MAP to disk" which creates a file with the adaptives tables saved..that way you can reload them and compare if you choose to reset them.
BTW: is you question based on curiosity (as mine was seeing I recently got the Sag) or do you have a problem.?

There is not really a problem that i know of, but i read that corrections of 30 percent are not ok. That is why i would like to know if this means something is wrong (or: can be better).
I re-adjusted the throttle pots tonight. Nr 6 was lower then the others. That is fixed now. Then i reset the throttle setting in the ecu and reset the maps. After a short drive, values seemed about the same as above...

You only have 2 throttle pots and they should read evenly when you open the throttle on the throttle display screen. When you say number 6 was lower are you talking about airflow with a syncrometer?I re-adjusted the throttle pots tonight. Nr 6 was lower then the others. That is fixed now.

it is true that to really feel the power you need to go into higher revs. But i don't really know how the power delivery is with a standard engine (i only drove mine for a couple of weeks before the rebuild and it wasn't running very well).
It's very similar except there seems to be an awful lot more happening above 3500.What you seem to lose is a bit of tractability below 1000 rpm.
The syvecs system on top really smooths it out and allows bespoke mapping to your style.
