I’ve scoured the forums over at stinger forum and here and am yet to find this problem. I just installed HKS M45iL plugs about a week ago. Closed em to a .022 like recommended by BMS and the car wasn’t running too bad. Couple sputters when idling (i read that’s the nature of the cold plugs) but...

Curious how the JB4 adjusts for ethanol blends. Does the map for e30 somehow get the engine to inject more fuel? Does the engine tuning adjust fueling on its own with the O2 sensor readings? If equipped, does a flex fuel sensor change any of this?

I hesitate to post this as I'm new and somewhat inexperienced. I just installed CPI a few weeks ago and have been trying to understand how to tune Map 6 on the JB4. Everyone keeps saying post a log (which is fine). Then I ask, "ok, thank you but WHY?" AWDGT2 was a huge help on jb4tech and the...

This includes the bluetooth connection kit and fuel wires with the harnesses so you can just plug them in. I am also including the factory plugs that came out of my Genesis as well as the gapping tool and feeler gauges from Burger Motorsports. Burger Motorsports Link

Looking to sell my jb4 in mint condition and bluetooth adapter. Looking for 450 local. Will ship at buyers expense. Located in Central CT, willing to meet up somewhat locally depending on how far. Only selling because I sold car and got something different.

I recently installed some electric dump valves on my G70 and had it dyno'd with the JB4 on Map 0, Map 2, then Map 2 with the Dumps open. Here is the full review, my thoughts, and install pics. JB4 - installed several months ago and has been a fun addition. I bought the 450HP kit with Denzo...

As title says

Hello everyone, New to this forum, but not new to cars. I am very new to the whole JB4 piggyback tuner. I have a 2019 G70 Sport AWD wih BMS intakes, and 1 step HKS plusgs gapped to .022. All of my other vehicles were ECU tuned. With that being said, I seem to be having some timing events with...

I might have overlooked a post from the past. But has anyone installed the EWG harness with the JB4 to control the boost by gear for a better launch. My G70 is RWD and from a stand still it spins like crazy. I have fitted my vehicle with 275s out back and 235s in front. Iv seen one post else...

For those of you that track with a JB4, do you have the gauges up while you drive to monitor anything specific? And do you ever get concerned while on the track that you could start pulling some serious timing as the car heats up and things could get damaged? I have a 22 G70 3.3T with JB4...

Hi all, I am selling my JB4 with the Bluetooth adapter + single fuel adapter. It was used on my 2021 Genesis G70 2.0T M/T, only needed one fuel adapter. Asking $600 CAD.

Anyone use/know of any aftermarket “performance” coilpacks for the 2.0 G70? Only could find one brand and they have no reviews. Thanks and have a great day!

New to tuning and modding my car and I plan on using Map 1/2 from what I gathered can be safely run on 91/93. Just installed AEM Intakes and will be ordering the JB4 and HKS Plugs next. Since I most likely will not be running the higher Maps is there anything else that might be needed to...

I am purchasing a JB4 tuner for my GV70 3.5t. I have tried finding someone who has made an install guide that is a little more detailed than what is explained on the website. I am not savy at all when it comes to car modifications. I was wondering if anyone near the Virginia Beach area or within...

I got around to dynoing my 2.0T g70 (Manual) with a jb4. I am running stock plugs and 91 octane gas. First dyno graph is stock vs map 1. second is I did a run with map 2 ( with stock plugs and 91 octane) It had more power down low but then petered out. I assume due to lack of 93 octane.
