Someone Cracked the Factory ECU
Well it looks like someone finally figured out how to crack the factory ECU. I'm still doing some testing, but initial tests look pretty promising.

They bypassed the electrical rev limiter?

My channel my car.
They upped the rev limiter from 6600 to 7400, increased timing to run on 93, removed the top speed limiter, and increased the valve timing a bit more. So far the car is still sitting on a trailer so I haven't done any testing aside from idle and rev it, but that'll happen this weekend if all goes to plan.

YES. Need more details!!! With this crack, can injectors be controlled?

Yes from what I was told injectors can be controlled I believe he leaned it out a touch for me as well but I won't know until I get it off the trailer and look at the logs.
I'm not sure how much remote tuning can be done since the guy who did the crack had to have my ecu in order to make changes.

If they can do DBW adjustment to get rid of rev hang, I'd buy another ecu just to send to them to crack and adjust.

The throttle hang is a complicated problem, alot of it caused by the really heavy and big factory flywheel. Even with the lightweight steel one on this engine it happens a bit.
The only thing I'm seeing in my logs is the throttle % going from 16 to 17 right as it nears 1k rpms which it does to keep the engine from stalling. But once everything can be validated and I get the go ahead from this tuner, I'll give out their info.

Yes definitely interested. I'd love to buy another XD ecu and have them raise the rev limiter push timing for 93 octane and get rid of the governor.
This would really help tie me over until I go standalone

If I could get rid of my AEM F/IC and run a tuned stock ECU, I'd be grinnin' from ear to ear.

Time to be a Debbie Downer. I'm all in favor of pushing performance limits but I want to urge caution in this specific area.
Having recently spent some time looking at the "unintended acceleration" issue investigations from a few years back, I would be very hesitant to do anything related to throttle control. The system is specifically designed to be resistant to unexpected feedback but as we all know, there are circumstances that will cause very bad things to happen. There's a reason they don't want you in the code, this being one of the bigger ones. It's considered a 10/10 safety critical feature by the FMVSS, meaning that a failure of the system can result in death or serious injury. I'm still planning on using a standalone (MegaSquirt) ECU for any crazy 1NZ builds and going with cable throttle. That means you can do whatever you want with rev limits, injectors, cam timing, etc. and not have to worry about a critical safety feature going awry and remove the laggy throttle response to boot. That said, this is still a major achievement and I don't want to besmirch xnamerxx's success. |
