2020 Singer may have a new 3.3 ECU calibration file..

[Terry@BMS]

That sounds like normal stuff. Calibration files change every year or two as manufacturers add new features or have to comply with new emission requirements. Just need to redefine your table addresses and you'll be off and running.

Emission standards ruining everything once again. It's not like those big boats that deliver our cars don't spit out more bad stuff then any car ever made. Oh wait.. lol. Emission standards should only apply to the Prius and other "look at me I'm saving the world" cars.

I will make an attempt to explain this.

Accel limiters have been activated inside of the ECU. What does this mean? This means that the ECU has an active distance that it can cover, before limp mode or some sort of safety is triggered. The value is measured in meters squared per time and distance is the value.

There were several other emission maps that were different, and a handful of maps that impact the throttle and torque delivery all over the ECU.

It also appears the hierarchy has been changed for operations. This means that the order in which the maps are used for operation has changed. How, I really do not know at this time, but I am working my way through the details in the engineering file that I made.

What does this mean? Well, not sure. I have heard a lot of people having issues with the new file/ECU while running a piggy back. Does this mean that you will not be able to run a piggy back, I doubt it... but it could mean that you will not get the same results as before this update.

If you curious about the differences.

The pre update ECU number was SIM2K-260

The new ECU number is SIM2K-260 1.01

I have mapped around 40% of the changes so far inside of the new ECU, if something critical pops up, I will try to share it with everyone.

Thanks,

John

Well that kind of sucks that they went and made such wide ranging changes to the ECU maps, I wonder what motivated those changes? Anyhow, I appreciate all the hard work you're doing on my ECU, John. Thank You

It happens all the time.

I just started tuning the Veloster Turbo 2nd Gen (ECU is a Kefico). I have counted 12 different calibrations to date, and that is in the last 6 months.

Manufactures do this to stop people from tuning the ECU (this is on the only reason I can come up with). For the Fiat community, I have over 60 different calibrations for the same engine. There is no reason the manufacture would do this, other than to make the life of a tuner miserable.

I question a lot of what Fiat does. Why they aren't pushing the 124 more is beyond me. If I could have found one anywhere near the spec I wanted I'd have done that and some faster DD project-ish car instead of the Stinger.

Hi. Could you share what the issues that have popped up on the 2020s have been? I have a 2020 and recently started having a symptom and wanted to do a comparison. Thanks

 

[Thorne]

The issues is only related to piggybacked or modded cars

Right. I have a piggyback and I'm also modded .

What is the symptom, may be an any year Stinger issue. Overboost , throttle close on shift, LC bog are popular...

It's happened twice under hard load and up in speed. Manually shifted to 5th and feels like the throttle closing, bogging and not up shifting. Fine from 1st to 4th. Wish I had logged when this happened..

 

[Terry@BMS]

Always need a good log to evaluate any sort of tuning problem.

If you wanna email me a log of what your talking about I'd gladly take a peak at it

Thanks but the issue seems to have gone away. I think I had some bad fuel put in. Normally I only fuel at one place but took the car on a business trip about 250km away. Had to refuel at an unknown place. After I got home a refueled with my normal location the issue hasnt shown up again.

 

[Ghoststinger]

Can't speak to your flash issue but I think your JB4 issue was something specifically with the JB4 you received and not related to the model year. Around 200 systems shipped between Oct/19 and Jan/20 had a setting entered overly sensitive that in cars with a noisier than normal electrical system cause it to cut out under boost. The fix is a replacement memory chip with the correct setting.

Terry is spot on him and I went throu6a week of why I had a freezing boost gauge and car falling on its face in all but map zero terry sent new eprom out a bam car was a animal

 

[G-602277]

Regarding the JB4 same here..Emailed support about the issue and received a replacement eeprom in 3 days. Installed it and the JB4 runs without a hitch.

Still waiting on the bench tune from John but I guess he’s still figuring out the new file. One down and one to go..

Greetings all; First post here..

I just picked up a brand new 2020 Stinger 3.3T about 3 weeks ago and so far its been an amazing vehicle. I've been building / tinkering with performance cars since the '80s and have built a couple of hot rods, owned a BMW M5, an Audi RS4, etc. I am so pleased with this car, and the engine, it is a torque monster! I really think this is my favorite car I have owned thus far.

As of now I've had my Kia dealership install Denso plugs, gapped to spec, and I installed the BMS air intakes. I also bought a JB4 but unfortunately the car wouldn't run at all on anything more than 60% throttle even on the default map. The car would go crazy rich on WOT and I could hear fuel popping in the exhaust. Anyhow, I gave up on piggybacking and sent the ECU last week to TORK for a reflash. Long story short, John says it has a calibration file he's never seen before. I'm assuming that could also explain the JB4 problems as well.

All told I've been without my vehicle for 8 days, but to TORK's credit they've sent me a replacement ECU with my factory file so I can get around while he sorts it out.

I'm curious if anyone else has a 2020 model year and is experiencing the same issues?

I'll keep everyone posted as this progresses..

I can confirm that you are very wrong in this assumption. As the same JB4 i used on my 2018 GT LTD works perfectly on my 2020 GT LTD.

We traced down this 2020 rumor stuff down to Tork spreading misinformation on the changes to try to convince potential customers the JB4 isn't compatible with 2020 models. Weird for them to do as it's so easily disproved but I guess desperate times?

Wait a second... are you suggesting a company as prestigious, respected, knowledgeable, or trustworthy as Tork Motorsports is ( being entirely sarcastic here ) would spread misinformation :O ?!

Tork is such a cancer on the FB group, in the very same fashion he was on the Mazdaspeed forums until he was finally ran out of town.

 

[Tonkabob]

Not sure how boost and O2 spoofing could be impacted by a year to year change but the ECU tune certainly can and did.
Wasn't the Jb4 issue a voltage spike protection shut down that you now raised the threshold on? Or was it a bad batch of units?
