The EVO8 has a fuel cut built in can this be disactiveted? IF yes how.

I have read quite a bit about the imobilizer where is this located in the map?

Thanks

the only way right now is to change your Boost Limit to the max which is 319 on all the columns.

Ah now I get why in one map those values where changed. Can these changes cause boost surge and detonation?

Boost surge - unlikely

Detonation - Possible, if you end up overboosting -> read: running more boost than your combination of tune and fuel can support.

Can anyone tell me which the boost levels equate to in bar? I believe the evo 8 runs around 1.3 bar so I wondered what 1.4, 1.5 and 1.6 bar would equate to in the value under the boost limit within ECUFlash

ie

230=1.3 bar etc ??

220=? bar
210=? bar
319=? bar

Many Thanks

Evo 8 (European version) gets boost levels around 1.0-1.1 bars. Maximum overboost you can get is 1.2 bars, but that is not a number you should be looking for in the maps.

Because of the load scale, I was wondering if the values in the turbo limit map ment actual pressure (over 1bar). The way I see it, they could mean pressure in psi. For example, 145 -> around 14.5psi -> around 1 bar.

This sort of explains what pressure levels we get near the rev limiter.
It is only an assumption, there is still a lot of work to be done before I can tell you more on this.

Could it be that the Load scaling is in Kpa absolute pressures.

so 230 = 1.3 Bar Boost = 2.3 Bar absolute pressure.

My EU Spec Evo 7 has a peak Bosst of 1.33 Bar and 1.2 Hold .
Also, the OE ECU has a the Fuel cut at around 1.4 Bar Boost = 240 Kpa = 2.4 Bar absolute.
Also the Load cells always max out at 260, will be 1.6 Bar Boost.
Thats excactly is what the Tuners know, that the OE Ecu is only mapped to 1.55 Bar Boost.
The Ralliart Ecu is mapped up to 2.2 Bar Boost ( maximum the stock turbos can do in low revs) so will be 320 Kpa absolute, exactly as posted roms show.

But the load is only an calculated number from Airflow/rev, Temperature and Baro correction, so it will have some small "errors".
The Japanese Engineers always work wit SI - Units, they never work with PSI / Bar / inch or something that way
