I think the correction maps that you are dismissing so easily is what you are looking for, check the KFSZFRL map, in combination with KFSZMN it gives szout (well, almost). And as far I as remember looking at all this, there is no FTOMN on this one.

Shit, I had grand plans to start doing some mild stage 1 tune on E85, prepped my program, ECU, logging. My Zt-2 seems to have died, I don't get AFR readings (they stay at 14.7). It might be that the connection to the sensor is broken (I snapped some plastic parts for the connector on the controller when disconnecting it last time, but I think I glued everything together fine), or the sensor died. So - what are typical symptoms of a dead AFR sensor?

EDIT: False alarm, bad connection, just don't see how on Earth was that possible...

Thank you Woj. I was so focused on trying to find it that i disregarded the rest to easily.

hi everyone, i'm trying to get more boost pressure with my td04, now the requested pressure is ok but the actual pressure con reach the requested pressure due to bad wg electronic calibration, i've made many try with the  wg duty cile map but without good result, what is the pid map for the boost controller? is like the diesel pid where there is the D, P and I maps, i've regulated correclty eith that pid on many edc16c39 map, but with the mito incompleted damos i can't find the map to increase the P valure of the turbo pid's and add more correction on the boost, my file is the same file from bravo 150hp sport that have teobolo

You're not the first and not the last to have problems with the boost controller on this ECU Wink which is over engineered. Playing with PID will not help you much, you need to fix the pre-control map, there is several of them, but your best bet is KFETAVD. How to tune it, I have no idea, and Mr. prj said somewhere earlier in this thread it's a futile exercise. Probably your best first attack is to try to copy the contents of this and other boost control maps from the Abarth SS bins.

This is all assuming you do not have boost leaks, which is another option, or that despite your faith in TD04 you are not requesting too much from it. Not to mention WG cracking pressures and related throttle things.

I briefly looked at these last files that you posted, don't have the correct definition for this one either, but I managed to check the obvious. I'd set the PVDXABS higher than 305 kPa just to be sure, but that's probably not it (it is the sensor's max anyhow).

More importantly, at 0xB6B2A you have a 4x4 map that you left untouched which is limiting RL to 220 all over (or so I think looking at my other esseesse file and definition). Try raising that. I called this map in the previous posts "MAXRL dep air density", because I could not find the right Bosch name for it. This is a word map with conversion X*1536/65535.

I am actually curious if that is it...
Bit of bump (sorry..). Trying to find the 'MAXRL dep air density' map on 0261201684 / 390454 (120hp Grande Punto) but it doesn't seem to be there (neither on 0261201685 / 391129 and probably more from the same family). I do however see a 4x1 map on A67F8 which is found in the mito damos under RLMXELDR / Maximum charge to protect against overpressure in turbocharger failure E_ldr. Also has the same conversion ratio. And i don't see that map in 0261201685 / 395673.

I think it's correct but maybe someone wants to take a quick peek Smiley.
