Just curious to see what other intake/exhaust upgrades people are running with their Hypertech.

In another thread it was suggested that Hypertech does not make provisions for intake/exhaust upgrades and such upgrades will cause the engine to run lean. While I can't confirm the accuracy of this information it does cause some concern as it's my contention these intake/exhaust upgrades aren't in the minority but should be an expected norm for Hypertech users.

 

Thus far this is pretty much as I anticipated, a CAI/High Flow Air Filter and Exhaust. If this is the majority of where Hypertech's users are in terms of upgrades this is what their target should be for their programs. At the very least they should modify their premium program to accommodate these upgrades.

 

Are you sure Hypertech hasn't already taken this into account?? Did Hypertech confirm they don't support high flow filters or modified exhaust? Is everyone who has high flow filters or modified exhaust running lean? I'm pretty sure I'm not.

Not exactly why it causes concern based on rumors. Personally, I hold my concerns until I get some facts. I have no information nor have I seen any thing on this forum that confirms a Hypertech engine will run too lean under any conditions, although I'm ready to be educated.

My 2 cents.

Edit: I emailed Hypertech for a definitive answer.

 

Reading is fundamental.

In another thread it was suggested....

I appreciate your contacting Hypertech to get some answers as it was my intent as well. The difference was I was planning on getting a feel for what type of modifications the average user has before I sent an email off.

When I last pulled my plugs at 30,000 miles I felt the insulators were whiter than they should have been, which indicated a slightly lean condition, although not to a point of concern. I haven't pulled them since and today with temperatures in the 20s it wouldn't be a good time.

 

Please correct me if I am wrong but The computer uses the Oxygen sensor in the exhaust line to see if the engine is running correctly and will make all adjustments for running lean (too much oxygen in the exhaust) or too rich (too little oxygen in the exhaust). It should do this whether it has the hypertech programming or not. This is the same reason Fuel injection is great for people like me. I live like 25 feet above sea level but regularly go to the desert that is maybe 4000 feet up. The engine runs correctly in both places even though there is much less air at higher altitudes

 

I have no idea what Hypertech is doing with the data coming off of the IAT sensor or the O2 sensor. An Air temperature sensor isn't the best way to measure volume of air and a change to the exhaust in front of an O2 sensor won't produce the same results as stock. Less back pressure means lower density and temperature also plays a role in exhaust density.

That said, having an idea of what Hypertech's target is and what my plugs tell me perhaps I can find a way to get the performance increases I expected. It could also go pretty far for the other owners of the Hypertech that believe they have a really expensive speedometer re-calibrator.

 

Basic K&N filter in stock airbox and hypertech. No exhaust cause I like the quiet ride. I LOVE IT!

 

AEM intake, MBRP cat-back and hypertech programer. No problem, yet...

 

I'll try to pull a plug in the next day or two and post a picture.

 

Indeed.

Until they confirm or deny they can accommodate the upgrades and someone can post evidence of such (a name from Hypertech would be nice, like Darnell maybe?), my 2 cents (also called an "opinion") is that this concern seems to be misplaced. Again - my opinion. Of course, your opinion is welcome too.
