These cars are notorious for losing traction right before the 1-2. Ive cured similar related issues with proper tire in the past. Are you running with TC completely disabled? If so, that could be causing your issue
The car consistently has this massive hiccup on the 1-2 shift on the drag strip. All 3 track visits every single pass. If it was a loss of traction I would absolutely think it would vary some if not a lot. For instance when the track is prepped really well right when they first start running VS late in the day and they will not bother wasting any more traction compound. I did not magnify it but I think the RPM rise was fairly consistent on the data logs. Lets see what Mike@OST says next time I hear from him. I sent the Data Logs to him.

You know what is funny. I know the car does this. But I was still shocked when it happened on my first pass today.

I would never ever fully disable traction control. I feel very strongly about this. I run sport traction/stability.

That sounds, to me, like it's running to quickly towards redline in first, and can't get the shift done fast enough before it gets to the rev limiter. I wonder if either raising the rev limiter a tad (but leaving the shift points alone, so as not to mess with your time, or dropping the programmed shift point on the 1-2 only would help this issue?
I had a Friend with a mildly modified Demon running in Houston last January in really good DA and his car had a Hiccup on the 1-2 shift. Alex Peitz lowered the 1-2 shift command 200 RPM and the Car picked up from 10.04 to a best of 9.77 So just that simple change made a world of difference.

So..........it basically comes down to this: do you leave it as is to keep the warranty intact and just live with it (or hope dodge can take OSTMikes findings and use them to fix it), or do you have mike fix it in the tune and potentially lose any drivetrain warranty should something break later? That's a tough call to make.

I think a lot of us are sort of in this same gray area right now. I'm not willing/content to live with this long term, will tune it if I have to. But that wasn't my original plan when I bought the car. Still love it overall though.

HP TUNERS FOR DUMMIES


I have used Diablosport in the past. But this time I went with HPTuners and I kind of like working on a PC/Laptop. So, no regrets going with HPTuners. I am not a computer scientist so I watched some of Mike@OST's videos and Speedy's videos. Very helpful. But no matter what there were some things that I just did not know.

The MPVI2 tool is pretty simple. Plugs into the Diagnostic port and then a USB Cable plugs into your laptop. Both tools I had needed a software update. So the minute it connects to the internet you will get a dialog box and it just takes a couple seconds. I recommend you have your computer connected to the internet and plug the tool & USB in and then wait before trying to do anything in the car. I was in the car first time trying to do something and that caused some confusion on my part because my Laptop was still connected to my network & internet and that dialog box opened up.

2018 and newer you need a security gateway module bypass. The security Gateway is to keep someone from hacking your car and crashing you while you drive down the road. HPTuners sells a Smart Cable to allow you to get past the Gateway module that installs deep in the dash under the radio (in a Challenger). I did not want to take my dash apart so I went with Z-Automotive double bypass cable and installed in the trunk with the OBD II connector running forward into the rear seat area. It works perfect.

If you have a newer car then you have to download the BETA version of the VCM Scanner/Editor software along with the drivers. The reason is they are constantly all day long adding support for things such as operating systems for your ECM and channels used in the Scanner etc. I had to contact HPTuners to add the Channels that Mike@OST wanted me to data log. They were excellent in their response to me and it did not take that long thankfully. But I literally had to go and uninstall that version of the VCM Beta software that I had just installed the day before and re download and install the version that was on their site that morning because they had just added the support a couple hours ago. Also I got a checksum error because I was trying to use the stable version and there was no support for 2020 RedEye operating system in there so I could not open files in the Editor.

If you buy credits to write tunes to your car, how it is done is they enter the info of your purchase on a server with the tool serial number. So, it is no big deal if you want to add credits later. In fact I bought the Tool and 6 credits and they were still not on the tool. You have to connect the tool to your computer and have the computer connected to the internet and do this. Open up either the Scanner or the Editor software and then at the top click on HELP. Then click on "Resync Interface". The tool will go and get the credits. Then they will show on your INFO file described below.

If you click on the Round Blue circle at the top with an "I" in it, that is the INFO button. Then when the dialog box opens click on the same icon inside the box and it will populate all the info. When sending in any problem to HPTuners they are going to want this. It will give a snapshot of what is happening with the tool, your laptop, ECM, TCM etc. So do this and SAVE it at the time of your issue. Super helpful info. I have made it a habit of doing this. The files will open up in note pad.

Another one, and this is a biggie. When you want to copy a tune from your ECM and TCM etc. you tell the Scanner to get info after you connect to the car. But on my car it does not auto load the hardware information. You get a drop down menu and nobody ever explained this to me. I had no idea what my hardware was. So, I had to guess. Well I was not getting a good read and I wasted some of Mike@OST's time because emails had to go back and forth. So, if you read the ECM (same as PCM), then that takes about 9 minutes. Well if the Editor then goes on to read the TCM it will take about 3 more minutes. Pay attention. If I had known this I would have known I was not getting a TCM read. I had guessed wrong on the TCM hardware selection. Well, the hardware version is in that INFO file! GPEC2A, 2018+ Dodge and ZF8HP, Dodge in this case.

Another one is, if all the channels you want to log are not active/connecting to the car. After you connect to the car and load or build the channels list you want, if you know they are supported but they are not working, then you can try this : at the top of the scanner page under the Vehicle tab, drag down and select "Repoll For Supported Parameters". If you are not connected to the vehicle this action will be grey/unavailable.

Well, I just got my unlocked PCM back from HPTuners today. HPTuners unlocked it and shipped it back on the same day. So, I have the PCM ready to go in the car, I know how to load the Mike@OST Hiccup Repair Tune that I currently have waiting to go into the car and Iwindale is running on the 19th. But I am still waiting on FCA to decide what is going to happen with my car and my issue. The Repair tune should not void the warranty because it doesn not change the power level. But they made it clear if the car sets a P1400 code my warranty is restricted, regardless.

I am very impatient and so I spent a lot of money getting ready to fix this problem on my own. Since I hit 108 in the 1/8th I decided I was keeping the car and was going to move forward on my own if they could not fix it. But then the SRT SUPER STOCK came out. So, now this train wreck. I asked FCA to build me a S/S to replace this car because Jim Wilder said the S/S will do everything I want on the drag strip. I am 100% sure he wants to see me racing this car. Probably Tim K too. But it's doubtful the people handling my case feel the same way.

I have not been driving this car. I put 500 miles on it to break it in and then I took it to Irwindale. So, it has been to the track 3 times to test and data log and to the dealer twice. Otherwise it just sits. I love this color. It looks SSOOoooo good under the Lights in my Garage.

If I get a S/S I am thinking of Hellraisin with a factory black hood.

19' Redeye
If it was me, I wouldn't waste the time trading from a Redeye to Redeye S/S. Unless you don't get killed with trade in value (that would happen to most people). The S/S doesn't appeal to me enough to trade in my 19" RE whatsoever! I wouldn't mind the demon brakes and suspension. However, the WB only option annoys me. Not everyone likes the WB, and the Demon 18" wheels are heavy. Every serious Demon racer ditches those wheels and crappy nittos. I'd rather swap out demon brakes and suspension, and mod my PCM than take the hit on a trade in. The WB option is a deal breaker for me, it kills the classic challenger lines. Now IF the S/S can be had like a Demon (1 seat no options), that would help it out a bit for the serious drag racer.

The WB RE Charger looks a lot better than the WB Challenger imo. Just my opinion of course, but the RE to RE S/S isn't a big enough difference. The only thing that would make me consider a trade in is a lighter platform at this point.

What's the PCM Dodge Mod? Hiccup fix or ?

Man FCA know how to screw customers. You better tell Jim and Tim to step up with this BS. Tune the car from the factory to hiccup then void your warranty when you get a tune to fix it.

This kinda stuff makes me not want to be a Dodge customer.

Yup this should be a recall. Every Redeye owner should get this fix.

Thanks for the update Ron, and for all you have done trying to push this up to the people who can possibly help. Their desire to just get you into another car worries me a little, perhaps we will have have to seek out the aftermarket for a fix. I was hoping better tires would help with this and possibly fix, but just today I was merging onto the freeway with MT ET Street R 305s on the back and rolled into WOT 2nd gear and it hiccup'ed on the 2-3 shift pretty bad. Was bummed...

Wondering if it would help to push another case like yours up through my dealer? Maybe more of us could? Think it would elevate to the people you know at SRT and they would give us a proper tranny tune? It can;t be that hard for them really and we wave the f'in flag for them like few others do...

BTW @DRAGRCR frostbite>hellraisin

What is interesting guys is with good traction and at about 80-90% throttle, it will bark the 345’s in the 2-3 and 3-4. It shorts that max RPM better than a guy can manually I think, and the computer lets it rip. The stutter at 1-2 is absolutely inexcusable, I am glad it like never is a problem on a road course because it is too slow. But, we cannot slam the throttle open, and/or don’t try it on the street or the same awful hiccup happens like Eric describes.
