RaceChip Customer Support - General Information

You might try sending them a private message. It might ping their email.

Indeed, when we get mentioned or a private message, we get an email.

Good question. When we develop our tunes, we always make sure that the AFR remains at a healthy level. We don't go beyond. So, there is no need for actively modify the AFR.

Of course, you might WANT to get even more power and WANT to modify it. The only issue here is that this can effect emissions. We don't want to enable our customers to harm emissions with our products (even though we sell our products for racing vehicles that are not registerd).
This is no final decision, only the reason why we don't offer it right now.

Thanks for the feeedback. Some folks had concerns with the PSI reaching 19.5 in my dyno test. Can you comment on that?

I would have to ask our engineers for their feedback.

If you can let me know what they say, that would be greatly appreciated. I’m on Map 7.

Yes, I'll let you know. This won't happen until Monday. If you want to lower your boost increase, you can go down to map 5 or 6.

The engineers said that your boost is slightly higher and your AFR is slightly richer than they have seen in their tests. However, they don't see any concerning levels. It's just important that you use some proper aftermarket spark plugs. The ones in the Stinger are not sufficient for such boost levels. Of course, such high boost levels might increase your wear and tear. So for everyday driving it might make sense to use lower mappings. But I guess you also don't use 102 octane for everyday driving.
A German customer sent us similar data. He has the car for half a year now and is still very happy. His car was even tested by a German car magazine (Auto Motor Sport). The results were very positive.

Appreciate the quick response. I don't plan to be running on Map 7 very often. Primarily only for the track. Yes, you're correct in that I will not be running octane fuel this high except for the track. As to the AFR being slightly higher than they've seen in their tests. Any chance there can be an update to lean it out to a still safe level of 11.5 as the tuners recommended at the dyno shop?

Forgot to mention that I'm using HKS plugs per everyone's recommendation.The only other mod I have installed the XLR. In regards to the German customer that you referenced does he have any other mods installed, Intake, exhaust, etc...?

For now we did not plan to go beyond offering different fine tuning mappings (when people have the app, we can change the software and provide it as an update). If people don't have the app they can choose 6 instead of 7. Why don't we go beyond? The problem of bypassing the ecu is that you bypass emission control systems. Even if you don't harm emissions, this is illegal. Our product is setup to be able to get CARB certificates.

As far as I know they only have some optical mods, no exhaust or intake. But you never know. Germany is very strict, so people are keeping it secret when they do things htat are not allowed.

Appreciate the info. That’s one downside to RC vs JB4 that you can’t control AFR.

Yes it depends what you want. The AFR you get with our product is safe, but it is the way it is. If you want to be able to modify it yourself and if you don't care about safety systems, warranty issues and the laws, there are other options that might suit you better.

 

[ryan1stinger]

Modifying the AFR doesn’t necessarily mean you want to put your car at risk nor your a law breaker. If your smart you can be safe with the changes and meet legal requirements.

Yes, you are right. I didn't want to say that modifying the AFR is a bad thing.
Legal requirements though, are a little bit more complicated. Not harming emission does not make things legal (depending on where you are). Sadly.

@RaceChip

Can you do me a favor and follow-up with engineering to find out what is the maximum PSI for the Kia Stinger 3.3 TTs?

Nobody can do that without compressor maps. As far as I know none are published, but if they are, that would be really valuable info for everyone.

The manufacturer knows their own products specifications and someone has to have an inside connection.

If you mean for their chip or the stock vehicle, then ok yeah they should know that. I interpretted it as you meaning the max PSI the car/motor/turbos are capable of producing.

I’m referring to the fact that anyone who creates a product that increases boost should know the max PSI for the intended turbos and I’m beginning to get the idea that know one does and that is concerning.

I'd be more interested in knowing the design limits of the impeller RPM on the turbos. Remember that those impellers are turning at tens of thousands of rpms and that overboosting them increases that speed quite a bit. You'll know when you've overdone it when you've cooked the bearings in the turbo and they start to howl.

Cheers!

Yeah without compressor maps everyone is kinda firing blindly. Someone will find out soon enough what they're capable of, probably the hard way

We have used the Garret Turbo Compression maps (OEM Turbo Manufacturer) to keep the boost within the stock impeller and turbo housing's tolerance. The stock turbos peak at just over 20 PSI at 1 atmospheric pressure (sea level) without accounting for the 1-1.5 PSI loss from inter-coolers and intakes. So even running the 19 PSI (approx. 17.5 PSI accounting for pressure loss from components), still keeps the stock turbos within the most efficient and effective operating pressures. For this reason we capped the boost at under 20 PSI for our customers. The stock turbos are pushed to their limits at just above 25 PSI so we are well under the maximum operating pressure.

We extensively test our products before we release them to the public. If we started to get rod knock, damage any of the impellers or engine internals, we would turn down the boost during testing. All of the RaceChip products are designed to improve power without sacrificing reliability.
