Great! I threw 1130$ in to toilet!
What you think about this? Did it last week with better fuel than 93
Here lambda starts from 87 than rise to 82

Easy killer, stay calm and work through it. If it says your box code is unsupported you likely just need to e-mail Chris that and he'll get it taken care of for you.


And the theory of some protection mode is valid, the ECU loves to throw lots of fuel at the engine if it thinks something is off in an attempt to protect it. Another thing I've seen in the Maestro logs is my torque limit drop a ton which in turn drops my power. This is also the engine protecting itself from something, but timing doesn't really retard and I don't get any knock. So I guess I'm saying, just because timing isn't retarding or knock isn't occurring, doesn't mean that the ECU isn't trying to protect the engine from something. It has several means of protecting the engine.

My guess us MPI injectors are dumping fuel and it can only control DI injectors. Sad thing is Maestro can control the MPI injectors but his ECU isn't supported. Sucks.

Should the ROW tunes not account for the OEM MPI?

I sent email to Chris and ask him about maestro for my ECU. This is what he wrote:
We do not have Maestro support for that one, just stage 1 and stage 2 software. We may offer Maestro support in the future. I do not have a firm ETA for adding Maestro support, it will depend on demand for that code and time available.

before I start to fight with ED on arguments could you look last time on this logs. You know these logs because I past them here. You have not seen last one.
First on Ron 100. I did it last week on 4th gear. Afr goes to 0.82
https://datazap.me/u/nicram1978/log-1533681362?log=0&data=0-5-6-7-14-17&solo=6-14

This one I did on Thursday evening with AFR like in tank!
I did it on RON 98 fuel from 3td gear.

This one I did 15 minutes later:

Is there a higher boost file?

No. I have access only to stage 1 or 2 for 91 or 93octan fuel.
I will be stack with jb4 so i will add 1 or 2 psi up top

New look into my case add George:
”On the MPI cars the secondary injectors are only used for part throttle driving and are off on full load.
Unless the AFR target has been changed in the software if they are on or off it will not make a difference. Assuming they are on the ECU will cut fuel from the direct injectors and still hit target”

Well, it's clear to me that you have excessive fueling. Yes, the target is changed by the tune, you wouldn't want to run stock AFR on higher boost. It's trying to follow a curve and it can't because as soon as you hit WOT there is too much fuel. Have you used the cable and built in diagnostic reader to scan for engine codes? Perhaps the o2 sensor on the turbo is faulty? Does your 100RON have ethanol to hit that 100 number? Is everything else in good order? No exhaust leak at the DP?

So the lambda discussion has my interest. I noticed that on the Stage 1.5 Maestro BT, my lambdas specifically targer down to 0.79-0.80.

Is this acceptable? My logs have been maintaining within 0.01-0.02 of lambda setpoint.

I do understand there is a huge difference in having a target setpoint at 0.90 and having the actual AFR at 0.80-0.82 and my case. Just curious if my lamdas are too rich.

Boost: 25psi
Octane: 96
