Noob, sorry for bugging everyone

[Jimmygilbo]

Hey all, got a 2020 GT2 AWD. Also, I haven't ever really been in a forum before, so apologies. I have work on planes my entire adult life, but that is all cut and dry, everything is vetted by multiple governing bodiew.

So far I have put on a Borla cat-back, BMS intakes, and the Mx free OCC. I did get the performance package from BMS, but have yet to install the JB4 or the spark plugs, I gapped them to .022" like BMS suggests, but haven't installed either the tuner or plugs yet. I am leery to put in the tuner, if/when I do, I don't plan to run over map2. Don't wanna risk blowing the motor as I plan to keep this baby a while. And I have no clue about what wires and sensors are what on vehicles hahaha.

What kind of Mx interval is running the Denso 5346 IKH24 at lap2 as a max, but only when someone wants to play(not for daily driving). I am not going to try and do the E85 mixing, it would just be 91/93 premium fuel with the extra boost from the JB4 if I were to do anything. As I said, this is all new to me but want to protect my equipment as much as I can.

Thanks everyone for any advice.

Howdy. You'll get nothing beyond a welcome, because I'm keeping the drivetrain stock. I plan on keeping this car for the duration and it's plenty fast enough for me.

Lots of modders on here though. Hit those boards and start reading and asking direct questions about this, that and the other thing.

Welcome as well but to your "mod" questions.... If you are new to the "tuning" game, best advice is to follow BMS directions "strictly". Can't express enough. With regards to the jb4, have run Maps 1 and 2 as "daily" and as long as plugs are up to speed and gas is as good as you can get, good to go. Just set it back to map 0 and then disconnect when you need to take it in for service.

If you decide to use it, submit a couple copies of logs to Terry@bms and get input before moving to a higher map. VERY IMPORTANT. That way, you can get professional input as to how the unit is performing with your car. If all is well, test the next map.

If you just want that "butt dyno" feel, then leave it on map 1 and enjoy. Plug change is still "recommended" but the MINIMUM for using stock plugs will be re-gap.

HTH

Awesome thanks. I have the plugs and corrected the gap, just haven't put them in yet, I will make sure that happens at same time/before the JB4

I will need verification from someone more 'well read' than me but from the forums threads i have been lurking DO NOT USE E85 as (i have heard) the car is not equip to handle it.
Only used capitals to highlight what needs fact checked. We will see in a few when this gets more replys.

There is likely a video (IIRC) for installing a JB4 on a Stinger. Hooking up the JB4 wires themselves is very simple, plug and play. If you want advanced data to/from the JB4, you'll need to run the OBDII wire through the firewall. It's a simple enough wire run, just takes a little patience to fish it though as one would expect. Just use the existing grommet for it, as is stated in the instructions. I personally just pulled it thought the gap you can make by pulling one side without making a hole, but I taped the wire where it touches the hole in the firewall so it doesn't rub through the wire casing. You can mount the JB4 wherever makes sense for you with double sided tape, or zip ties. I used strong 3M double sided tape to tape it to the battery box on the passenger side. If you want to go a step further, you can also tap the fuel wires. You can either to a wire tap, or you can get fuel wire harnesses from Ecko04 if he still makes them, or there are other sources online you might be able to find them. I like reversible, so I got the fuel wires from Ecko04.

As for daily use, I don't recall any horror stories from anyone using map 2 on a daily. I found my performance (0-60 and 1/4 mile) not keeping up with others' and I attribute this to Canadian gasoline. We supposedly have Shell 91 as our best offerings and others claim our 94 octane is snake oil, worse than Shell. I believe I was limited on fuel octane and only bested 13.3s on the 1/4, I expected 12's. The car was noticeably faster in any regard, with the JB4. If you have access to good 93 octane, I'd say you can run Map 2 easily on a daily if you've not pedal to the metal all day.

Installing the plugs is doable yourself, but a nuisance. The 2 areas that were a pain for me was the passenger side middle plug under the arm of the intake manifold, you need some swivels and a magnetic (or rubberized to hold the plug) spark plug socket. Getting the coil pack in and out is a little bit of a pain too since the boot is fairly long. You can pull the boot from the coil pack if it helps, just don't lose the little spring in between the two. Leave either the front or rear coil pack on that side out when you do the middle, but I forget which, probably the back. The other thing to watch is some people including me have had a little trouble getting the bolt started on the first thread when putting the coil packs in. If you run into this, just be patient, jiggle the coil pack a little and make sure you get the first 1-2 threads started by hand before you wrench.

I use the OBD2 cable/connector as well BUT I got lazy with the cable and ran it along bottom of the windshield tucked in with the jb4 cables and around the door jam to the inside of the cabin, driver's side. When tucked in properly, you have to be next to the door to see it. easily removed along with jb4 when time for service. Sorry, just got lazy but it works for me.

Yea i wound up routing mine today, did it through the firewall. Haven't tackled the plugs yet, so havent actually installed the JB4 just prepping what i can. Project for weekend will likely be the plugs, blah lol
