    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

Terry: I run map2 on CA 91 octane all the time, never an issue. Your mileage on Canadian fuel may vary. As has been discussed log both and see what looks/works best for your particular situation

The Official 1/4 mile track thread

We want to hear the results today!! ha ha
 
I believe this has been asked before but just want to be sure before I pull the trigger. But looking at running map 2 with the fuel wires the likelihood of anything drastic happening to the engine is relatively low correct? I assume the higher boosts and advanced programming that are pushing the limits on the engine are where the Stinger people I’ve heard about are toasting engines. I just want to add a bit more HP but not grenade the engine.

I have the same concerns and desires. I am running Map 2 with 91 octane and fuel wires, and all is OK thus far. But I don’t hammer my engine very often and am in Comfort setting almost all the time with light throttle inputs. So far, it’s running fine with no hiccups. But Map 2 is clearly present as it “hits” pretty well when accelerating from 10 mph, and it easily kept pace with a brand new Camaro SS.

Maybe I missed it but I don't believe anyone has blown an engine due to JB4 in a Stinger or G70. There is one guy on the Stinger forum that appears to have a blown engine but he's also mysteriously missing most of his oil and coolant. TBD on what happened there... and from what it looks like so far, it's doubtful JB4 was related.

My GXM told me that Genesis engineers said the 3.3T was designed for 520hp as a daily driver. I really can't see how Map 2 would possibly do any damage even if you're really hard on it.

Well sounds like I’m ordering a JB4 today.

Thanks for the input. That’s what I love about these boards. Everybody helps out each other.

Yeah cause the Denso is ultra cheap and a couple of heat ranges colder than the stock V6 plugs. So by default already safe for the JB4. The HKS is just a much sturdier plug but probably overkill anyway.
For the 2.0T, the HKS and NGK are the only colder option. The rest are all stock heat range.

I'm planning to install the HKS gapped at 0.24. Can I run them without the JB4? I planning to install the new spark plug today and then wait for a friend to help me with the JB4 later on this week. I'm using 93 octane.
 
Yeah shouldn't be a problem. Worse case scenario, it will idle a little rougher.
 
Is that the tmap or the map sensor? Looks like the map sensor using the part number. I'm trying to find them. There is like 0 guide online for the 2.0. Thx

ever any update if bms ended up making o2 extensions or not?
They didn't want to make one until customers started making or sourcing their own. Now they have committed to making one but no ETA for when it will ship!
 
I emailed them about the extensions and this is their reply.


Hello, yes they will be out but they are not available yet. When they are we will have them on the site.

Thank you for contacting BMS!”
 
I just ordered the connector kit from Ebay and will build it myself.

well thats kind of vague. i contacted them about the strut braces and seeing if i could get enough people together for them to get a batch made for the g70 and they never responded back after that

get your intake yet? my replacement parts are supposed to show up tomorrow

Not yet. Still waiting!

Did a number of runs just now on map 2. 0-90ish mph. It certainly pulls even harder than map 1, but, I worry about the ECU pulling a little bit of timing roughly right below 3750 rpm, despite it being relatively cold outside (66ºF at night). Comparing my logs to Map 1 at the same RPM's, it doesn't look like it's pulling timing in that same area. All RPM's above that are great, though - no timing pulled. Interesting thing is, after a few runs, the ECU seemed to learn a bit and not pull timing in that area anymore.

Take a look... First few runs, essentially back to back. Circled is the area where timing was pulled - you could feel it drop a little bit of power at that RPM for a split second.

By the 4th run, the timing began staying more consistent. No more perceptible drop in power.

Now take a look, this is about the 5th run, no more dip in timing in this area; however, it looks like it's starting out with less advanced timing to begin with after flooring it. Looks like the ECU has learned to trim it back a little beforehand so it doesn't feel like it's losing power in that spot. That's amazing...

Lastly, here is map 1 when it was really hot outside.

Map 1.jpg


Now that I'm looking at all of them at once, it actually looks like the timing is very similar between Map 1 and Map 2 when comparing my last couple runs of Map 2 to Map 1.

I wonder if the JB4 is causing the ECU to think the boost is substantially lower at that RPM point, so the ECU thinks the timing should be more advanced. However, since boost, at that given RPM, is actually higher than what the ECU perceives, knock potential rises. When switching from Map 1 to Map 2, the ECU thinks the boost is even lower, so timing is more advanced, when in reality boost is actually even higher, so it has to dial back the timing... I suppose it takes a few pulls to compensate for this.

Either way, I will have to log some pulls during the day time when it's hot outside and see if anything changes. Until then, it looks like Map 2 is working well on my car with 92 octane pump fuel; but so far it's only verified when cold outside.

On a side note: Despite being 66ºF outside, looks like my AIT's ranged from 91ºF all the way up to 118º (after doing a few back to back pulls). That said, I think there is some room for a bigger/better intercooler, and possibly even some heat reflective tape on some of the intake piping.


Damn. This car is getting fast already. Excited for more.
