i didnt find it, but tried it and have to do it like in the Evo X

How is you fuel table looks like ? I have PTE780cc scaled to 713cc and 14volt 0.768ms, the fuel trims are ok, near to zero, lean spool turn of set star/stop rpm to 8000/8250rpm but I have to enter in the cell quite low number to get 11.5 to 10.9 afr.
it is my 240cell from 3000rpm . the intake is stock .

The values for AFR above look more like logging incorrect input or wired it improperly.

Also, it may be of interest for those visiting this thread - I've posted improved xml for 88580714 ROM (TephraMod v7 for EDM EvoIX), details are here - https://www.evolutionm.net/forums/8806311-post2094.html

Also I've finally installed Grimmspeed 3-port boost control solenoid and last Saturday made preliminary boost adjustments. It works perfectly, iтstall was extremely easy as well (all you need is vacuum hoses and directhand.dll).

These afr values in my fuel table to get my desired afr on the wbo2 . 11.5 tapper to 10.9 . I know these are just numbers but seems like quite low with disable lean spool up. in my evo 8 v7 also with upgraded injectors in the fuel table boost area i have to write 11. not a big problem because i have the afr what i would like just interesting..

Rear O2 heater CEL disable is great

psi based boost control also working ! Great, thanks to everyone.

So I feel I can share current results with everything installed (Omnipower MAP-sensor, Grimmspeed 3-port BCS, Tephra v7 ROM with direct boost, DC Sports downpipe, everything else with the car is stock). I've tried for 1.3bar flat boost curve. So far it is quite close with following settings:



It gave me following boost curves (still some work to be done with target boost mainly):

nice result VD with some play we can make so flat boost with direct and gear dependant boost control.

can we buy somewhere connector to the JDM 3bar map sensor ?
or better just buy an gm 3 bar map sensor with the connector, and do not have to drill the manifold and like this. the gm 3 bar is also ok for psi based boost control ? maybe for SD conversation better to buy jdm or omni4bar map ?

part numbers from bosch for connectors and pins are listed within this topic.

sd conversion so far is impossible since noone bothers to tap for IAT sensor. if someone does, let me know and i'll try to port the IAT monitoring patch to our ecus. from there it would be easy to do SD on european evo ix's.

i think will go on that car by gm map sensor because it is the eaiser way just plug it in some boost vacum line search will come with connector. I wouldnt like to remove the IM.
I just need to find pin in to the #92 plug.

I ordered my IAT sensor ! I will let you know what i will get it. And if it is possible to run speed density too
But which map sensor is better for SD ? Gm3 bar is right to or better to go with Omni 4bar ?

How to disable fuel cut at 319 load with the Tephra V7 88580714 rom ? Is there any Fuel cut X2 table ?

Thank you Donner ! Did you notice the 1byte load is higher in hot days with that rom ?

iTrader: (1)

I have not really compared roms this way, 88580714 seemed to work fine in my EDM car even it was around +35C at this summer. But I noticed that temp&baro compensated load (6B28 and 6B29) is lower when it is hot but that is natural Do you mean that 1-byte was higher with same boost when it was hot?

VGergo

Yes 1-byte load with 26psi boost was ~280load at cold temp when it was tuned, but than in +35C 1-byte load hit over 300-310 load with 26psi boost too ( psi based boos control ) and fuel cutted the car .
