I have a Hypertech Thermomaster Power Chip w/ 160 degree thermostat, and it seems to be working well.

I have heard a little hype about a part specially made for 82 and 84 vette X-Fire engines. This is called a- Throttle Performance Switch.

It is relatively inexpensive for what it claims to do (99.99).

I just want to know if it will work in conjunction with my Hypertech Chip, or if it will work against it, or if it will work at all.

The Hypertech ThermoMaster Power Chip claims-
"Hypertech recalibrates fuel delivery and ignition timing from off-idle to red-line, to deliver maximum torque and horsepower for significantly impoved acceleration and top-end speed."
Installation- Just replace the computer chip with Hypertech Chip.

The Throttle Performance Switch claims-
"Our Throttle Performance Switch will provide an immediate improvement in throttle response and maximum amount of fuel and timing advance."
Installation- A direct plug-in to the throttle position sensor.

They both affect the fuel and timing, but plug in at different locations.
This won't screw up my hypertech chip if I put it on will it?
Do you think it will help, hurt, or stay the same?

Thanks,
Andy

Andy1983,

Did the chip make a big difference in performance? Is there a noticable difference in gas usage?

I have the Hypertech Stage II chip and have had the Throttle Performance Enhancer with it. Ran both for about two years. Then decided to get rid of the Enhancer. Honestly, I notice no difference without it. The ONLY thing the Enhancer does is tell the ECM you are at WOT when you are really at WOT. Thus, supposedly, you get the benefit of WOT earlier. But, think about it, if you are going to hit WOT, you will do it by mashing the pedal fast, not slowly. I bought the Enhancer when I had more knowledge challenged, and not $ challenged.

I recently tried eliminating the Chip. Now that one made a difference. You can get use to the Chip and not be cognitive of its benefits. But, after a week of the Stock chip, I put the Chip back in. It does make a difference.

Please, save your $ on the Enhancer.

Racer, it made a very nice boost in performance. I felt it BARELY, but my dyno tests showed almost 7 hp gains off of it at some points (averages about 3). Pretty nice for a quick install.

The gas milege on the other hand has been tested by several different people (none on vettes). The sad thing is that it helped like .1 mpg after like 1000 miles.... so it is nothing.
I would still recommend it though.

But Larry, couldnt the performance switch still help with my 1/4 mile time or quick street races (against ricers)?

Andy,

7hp? That's it? This was at the rear wheels I hope. I always thought a chip was good for about double that.

Andy1983

I have tons of other bolt-on add-ons for horsepower.

Chips are awesome, but the main reason is because I drive from Plano, Texas to Norman, Oklahoma alot, so I needed the car to run cool (with a 160 degree thermostat). It actually improved... I was sceptic that a thermostat would run my car cooler, but this chip made it awesome.
Btw, I tested it immediatly after I added the chip, so it probly cleaned the spark plugs and will run better as time goes on.

Come next winter you will be taking the 160 out, because of the LONG warmup, if it does in Dallas cold winters.

I really don't think the Enhancer enhances anything. But if you are determined, have at it.

I always warm up my car in the garage (with door garage door open so I don't kill myself), but it is plenty warm in the garage (we usually have a little heater on because we are always in the garage anyways ).
I'll tell ya what. I will install it and dyno test it to give the "official" result.

larry82 who should i get a chip from?

IMHO, I've been running the Stage II chip and 160 thermo for about three years and was impressed from the minute I put it it. cost around $100 - $150 for the chip, M/A or Zip, my kids got if for me for Christmas. I picked the thermo up at Auto Zone for around $2.00.

I had to retard my timing to avoid pings at mid to wide open throttle though. I'm running at 7 degrees and she does fine. No other mods have been done, she is all stock with exception to plugs (A/C Rapid Fire) and what I mentioned above. Performance wise I am happy, at 152K on the motor she gets around 23-24 MPG on the highway yet I can still turn the BFGs over off the line.

I am a purist with this car, if it was not on the car at the factory it doesn't belong on my car...unless you can't tell I've done it like the chip! Plan to go into the motor somtime. That will be the challenge. Port/Polish the intake for sure and some other mild mods. Watching the CF artilces closely though. I don't think I will be able to do all of their mods but it will steer me in the right direction. :cheers:

The enhancer has been discussed on this forum many times and I think the benefit of the enhancer is in direct relation to the way you drive. If you do a lot of part throttle kickdowns around 75% of throttle as I do you will feel some benefit. If you are a to the floor, WOT guy you will see little or no benefit. The total thought behind the enhancer is that it tricks the chip into thinking you are at WOT when you are not and this will cause full advance and mapping to kick in. The chip will make a big difference and part of that big difference is that it prevents trans lockup in 1, 2. & 3 which in itself can be controlled by a switch. I use the 160 degree thermostat, power chip II and the enhancer which is a good combo. The biggest thing you need to be sure of when running the 160 thermo is that you are going into full loop on the computer. The 160 degree thermo will actually allow your heater to warm quicker due to the lower release point but it will not be as warm as a 180 etc.

Cruise on!!! :seeya
