I liken it to sticking your head in the sand. We do have various view levels that hide many uncommonly tuned parameters to make the interface "simpler". However we do understand that in many cases if you are only touching a few tables that you do not want to see 30,000 tables and scalars, hence...

The avid device is very slick in my opinion, if you want something permanently mounted it is worth the premium. There are obviously cheaper options if you don't want a gauge or anything dash mounted though. Most of the big tuners are offering to deliver PCMTEC via Avid, XCAL 4, Direct flash...

Let's keep the industry alive and instead of wasting money on a tune + fake cats buy 1 or 2 of those cats Greg banish recommends imo. They will get cheaper the more people buy them. https://www.hotrod.com/how-to/catalytic-converter-vs-straight-pipes-horsepower/

No problem. I find this kind of stuff fun when I have the time to go digging.

From a brief look at a 2020 GT this is what I could find ECT between 160°F and 260°F Ambient temp between 44°F 140°F Cat temp between 1,000 °F and 1,500 °F AFR must be matured (if its a flex tune) Fuel level must not be low O2 sensor heater must not be in a failure state (uses some...

Everything you change from stock decreases the chances of the tests passing. Especially if it's winter and cold there. You have to be in very specific conditions for the tests to even execute let alone pass. Most dealers here in Australia send cars out with half the monitors pending. The PCM is...

PCMTEC can read whipple tunes even with scrambled OSIDs. We don't enable OSID unscrambling by default unless it's your own tune and you are porting over to our ecosystem. However contact support and we can always help out where possible.

You may be able to dowgrade an S650 to an S550 electronically with the right amount of patience. Though it begs the question, why not stick with an S550 especially as you'll be likely modding it out of warranty.

Just on this topic I got basically all the electronics from an entire F150 from the middle east shipped to Aus. Cluster, PCM, BCM and about 25 other modules with looms. People just leave brand new cars crashed everywhere. Find some contacts, be loyal and they will return the favour. Their...

That is why we went the route of writing custom firmware that is called from the OEM firmware for our new functionality. No re-inventing the wheel. The PCMs typically have loads of spare ROM/RAM however you need to be a competent programmer to write these sets of custom firmware and then...

These tools already exist eg WinOLS/Ghidra/IDA If you have the expertise to modify firmware/checksums then likely you also figure out how to modify the modules as well. It is no small feat. Ghidra is free, try it out and see how you go on something simple like notepad.exe Here is a tutorial so...

Very interesting. I guess it opens up room for an exploit for someone with the right skill set. The HSM is ARM as well which increases the number of developers familiar with the assembly langusge.

If the key is leaked they will make new hardware. By the time it occurs everything will be our of warranty anyway.

Absolutely. The issue is it would cost us over 100k in R&D to do it in a generic manner. So we would have to sell thousands of IPC mods to break even. So for that reason we say no to the majority of requests. It's simply not possible to do and continue to pay staff. If you could guarantee a...

256 bit is brute forceable if you can reduce the key space, eg you know that the mechanism used to generate it is flawed. That is how they cracked the 1024/2048 bit RSA keys on other infineon processors. I believe they reduced it to 50 CPU years to crack, 50 years is a long time, but with say...

Even as early as 2002 Ford stopped using tip in enrichment. They do use tip in spark retard. They did add a feature called "airflow anticipation" which they use even on MAP cars when they see a sudden change in airflow which does a "tip in" style enrichment, but as you indicated that is only...

Old post but could this be due to the VCT timing in fuel economy mode where they want the throttle as far open as possible to reduce pumping losses?

It is SD. Wengerd is very clever and didn't do this this overnight. There are a lot of gotchas.

Do you have anymore info on this? I can't see anything about any aftermarket 10r80 controllers, even the 6r80 ones are a step backwards if you want to do daily + track + drag. Motec can and could do a 10r80 controller, they however take a huge cut and own the Ip of whoever develops the firmware...

Eg cracking the iPhone. Fbi couldnt do it but a firm did it for a bounty exceeding 1 million. Put the ram in dry ice, shave the lid, xray it at the right time and if you know where the needle in the haystack is voila. What you then do with that needle is a whole another story.
