LOL.. no changing gear..

Hi,

Could someone please help me understand why, at 1216.476 in the attached log, TPS and MAP decrease as I take my foot off the throttle, yet RPM increases for the next 300ms? (from 5500 to 5875). All other logs I have seen show TPS, MAP and RPM in Sync. I can't see RPM smotthing effect this, but ...

David.. yes that's great thanks. From what IAT would you start retarding?

I think I have achieved the same thing by changing IAT Fuel based corrections under "Other tuning" in MSII.

I have GAIR now constantly at 100% as I had heat soak issues on restart.

My table is (in deg C)

IAT Deg % corr
8 0
21 0
33 4
46 8
58 12
70 16

Hope this helps

Is there a rule of thumb scale on the how much to retard the advance based on a certain IAT? The defaults seem to very require a really high IAT before retarding starts. Reason for asking is now that summers starting (in Australia!!) my fibreglass bodied car is getting quite hot .. and IAT are ...

Kannst Du mir ein PM schicken.. Ich moechte mich vorstellen?

I too have noticed improvement in sim/4 squirts in my 5 litre Rover based V8 in my TVR (green ring Injectors).. however it does mean small chnges in PW have a large effect in AFR.

Sim/4 squirts is definite the way to go..

What a interesting thread.. I have gone from 4/Alt to 4/Sim on my Rover V8.. with such an improvement.

Currently using Lucas Green injectors..is there any impact on injector wear when doubling the firing?

Hi.. I have exactly the same question.... does anyone know how (or if) this is possible??

Many thanks
