6MT Owners - Discussion Thread

Gapping the plugs is a must, but i had much better results in the .028-.030 range, not the .022-.024 range that is recommended. I ran both the HKS and OEM plugs, but since i never went beyond Map 2 i actually found OEM worked best. I eventually realized the insulators on the HKS plus were cracked which was causing misfires. Annoying as sh!t since they were so expensive. Make sure you run the highest octane top-tier fuel, like Shell 93. i did better with that than Chevron 94.

Where I'm at we only have 91 octane readily available, so I was just going to stick with map 1 and probably just stock plugs unless I hit issues. (If you think i'll hit issues i'll just gap them soon enough ) I see you also have a manual and I've heard its a pain in the ass to run the odb2 cord through the grommit if you have a manual, did you brave through it or just door jamb?

 

[canucklehead604]

^ oh, yeah. i just did the door jam routing. worked perfectly fine for me. it is essentially not noticeable except if you look closely while opening the door. if your car is black even better and i doubt you'd see it at all!

you'll need to re-gap the plugs but give it a shot stock to see. luckily our 4-cyl layout makes re+re of spark plugs super easy and it's a 20 minute job.

I gave it a shot stock with 91 octane, I posted in another thread as well. I assume that the map2 kinda died out at the end due to not being able to run it out on 91 octane. Sadly I did forget to run logs.

 

[canucklehead604]

^ nice graphs. so i see ~+25Whp and ~+35Wtq on Map 1. that's on 91 with no plug re-gap. i'd love to see what 93 and a re-gap would get you. my butt dyno on Map 1 felt like your Map 2 numbers. to me Map 2 felt like another ~10-15Whp/Wtq over Map 1 which is pretty much what you show, it's just that i think you'd see greater gains with better fuel and a regap.

any issues with detonation, or was power delivery smooth and uninterrupted? i did see some detonation before i regapped.

As far as I can tell, I’ve heard no knocking / seen no codes. I’m pretty happy with it, I’ll get around to regapping the stock plugs eventually, but so far I’ve seen or felt no ill effects. On the 93 front they don’t sell it here, some gas stations do 100 octane but it’s not common enough for me to realistically run it ( well a blend ). I do want to give it a shot though, if I move to a place that has it I’ll definitely do plugs and run 93 as default.

Hello, this is my first post. I'm going to look at a 2.0T Sport 6MT this morning and am interested to see how it performs with the manual. The reviews are so mixed, I figured I'd need to try one for myself. One popped up at a dealer an hour away, so it seemed like a good opportunity to check one out.

Does everyone still have the power dip issue at clutch release? Or do you just learn to deal with it? For those with a JB4 or other tune, does that alleviate the issue?

I'm interested to see if I notice it during the test drive.

Thanks,
Ted

I've now had my 6MT for ~36k miles, bone stock, and the power dip is still there if you look for it. However, my clutch foot has learned, subconsciously, to drive around it such that I don't notice it any more at all. Even hopping back and forth between my G70 and my S2000, I really don't notice it. I do 95% of my driving in Comfort mode. It really has become a non-issue in my enjoyment of the car. And having spent time in both 2.0T and 3.3T G70 automatics, I can say that the 6MT is by far the most fun of all of them.

Where are you located? The lease is up on my car in May and I plan to buy it out with the intent to sell it, if you want another purchase option.

 

[canucklehead604]

^ good summary. i find the 'dip' most noticeable in comfort mode. eco is better, and sport is best. i spend most time in sport. JB4 didn't do much to help or hurt it.

TedS123 is right - you need to drive the 6MT for yourself. manual operation is much more personal and varied than a slushbox. what one person loves another person could hate. go check out that unit nearby and let us know what you think!

Just got back from the test drive. I live in rural Culpeper County, Virginia, and the car was in northern VA. It was hard to find a windy road to test the handling, but there were plenty of stoplights to try the clutch take-up!

I can definitely see what people have said about it. I did stall it twice, and noticed a bit of a lurch on several occasions. But while I wasn't as smooth as on my old car, I adapted to it well enough by the end of my ~40 minutes with it. It's not hard to imagine learning to adjust to it. Aside from the engine tuning quirks, the drivetrain was enjoyable. The engine seemed to have plenty of power from a wide range of rpm's and made an enjoyable exhaust note.

The transmission itself was fine. It may not be quite as precise as my old Mazda 3, but it was perfectly serviceable and I enjoyed driving it.

I've been cross shopping several rear-wheel drive cars looking for a good balance of fun, comfort, and practicality. So far I've driven a 2019 Stinger GT2, 2022 BMW 230i (with and without MSport suspension), and 2022 Toyota GR86 (unfortunately only in automatic). So the G70 2.0t 6MT falls in the middle, with the GR86 and Stinger at the extreme ends of size and fun vs practicality.

One question: I remember seeing reviewers talk about how the seat bolsters tighten in Sport mode. This car didn't seem to have any adjustment to the bolsters. Is that normal for these cars? Is it only the upper trims that get that feature? I would have liked a little tighter.

Adjustible bolsters is available on the 3.3T, but not on the 6MT. That may be available on Canadian spec cars? Canada does get a few different features on the 6MT than USDM cars, including the quilted leather seats, so that may include the bolsters.

The handling, ride/handling balance, and brakes are the best part of this car IMO. There really is no better manual sports sedan out there for the price of the G70.

That being said, I have a CT4-V Blackwing on order.

Oooooh, that's nice. I would love to try one of those. Excellent choice (based on all the positive reviews).

Good April 1 radar, but I'm serious.

^ the CAD 6MT trim got the trick seat bolster thing along with a bunch of other goodies (basically, it has all the same appearance items as the 3.3T plus the extra mechanical goodies that the US 6MT car gets). but, your US spec got vented seats which CAD doesn't get - doh!

with the 6MT trim you also get the sport exhaust and the sport "euro" semi-metallic brake pads that was only offered on the 6MT and the 3.3T RWD Dynamic trims. awesome pads, but hello brake dust.

your assessment of the gearbox is pretty much spot on. it's fine. not the best, but far from the worst. to be honest, it is both the best AND the worst in it's class since it was a purple unicorn among its competitors from '19-'21 - nobody else offered RWD/6MT/LSD in the segment.

i also tested the 240i Msport w/6MT. tons of fun and great gearbox but just a tad small for my current situation.

 

[TedS123]

Thanks for the info on the different specs for US and Canada. Bummer about the seats - the other cars I've tried all had pretty snug bolsters, which I liked.

Another question regarding the JB4 on this car: how does it affect fuel economy?

Sorry, another question for you 6MT owners who have driven the other versions of the G70 and/or Stinger: how does the handling compare? The Stinger I drove was the GT2 with adaptive dampers in the sport mode. I drove it on familiar local twisty roads and was impressed with the grip and lack of body roll. The G70 6MT I drove was in a more urban environment without a lot high speed turns. My impression was that there was a little more body roll, but still well controlled. It still seemed comfortable and quiet.

Just wondering what those with more experience have found.

Thanks! Ted

^ oddly enough, i found fuel economy improved with the JB4. when i was in Eco mode and driving reasonably - i.e. city commutes, etc.

That's interesting and encouraging. How much of a difference did you see? Fuel economy is one of the criticisms of this trim. I'd love to see the new 2.5T from the Stinger GT-Line in the G70 for the improved power and economy. My daily commute isn't too city-ish, so I would hope to get closer to the highway rating on this car.

IMO the presence of a manual trumps all the other considerations. I don't think I would have even considered a G70 if it was auto-only. But to answer your question, when I was shopping I did drive a Stinger and G70 6MT back to back, and something seemed a bit off on the Stinger with regard to handling...it didn't feel as nible or as planted as the G70. With the G70 6MT, there is a bit more body motion than you might want on a twisty road, but I have found it to be about as good of a ride/handling tradeoff as you can get in a sport sedan with non-adaptive dampers. Really perfect for a daily. Despite the body motion, it doesn't lose a step with turn-in, steering feel, or absolute grip....those are fantastic. Same with balance. To me it feels a lot like a stock E36 M3.
