Engine/Transmission (1998.5 - 2002) Hypertech programmer

[jpmutt]

I'm going to install another pyrometer (pre turbo) and just find out for myself and put an end to the wondering what the temp actually is. This is probably the most controversial subject on this site. I was going to install the thermocouple pre turbo in the first place, but my laziness got the best of me. I would really like to just install a second thermocouple and be able to switch between the two, using one gauge. I have heard of this being done but I'm not really sure how to wire it all up.

Auction close in 3 days no bid yet, but someone is usually out there to the last minut

 

[jpmutt]

It won't work on my truck (2000). My sensor is a round three pin connection. Thanks though.

 

[cyborg]

Alrighty then.....

My results are in.

Hypertech adds more power and with the last two tank fulls, tire size calibrated, I'm getting 17. 8 MPG.

I have a couple other bombs planned, but not much.

 

[jpmutt]

cyborg, what kind of mileage were you getting before the hypertech was installed? What size tires and gear ratio? I have 285's and a 3. 55 ratio.

 

[JBlock]

I think the boost fooler on ebay moght work, if you had a rund three to straight three adapter, I believe some of the people use them with edge EZ to switch years. If so maybe someone can give one if it not required on their setup and mail it to you.



good luck.



Your mileage is up that good, I got a superchip programer, and only by seat of the pants and overhead. it looks like mileage about the same or worst on the middle setting 50HP, i never have set program to the 70hp setting, As I have a stock transmission plus 3 turns on the pressure, and RV275 injectors. I had a comp set as an EZ but my wife said she would get a tickets if I left it on.

 

[cyborg]

I'd get 15-16 consitantly. Of course I like the feeling of the throttle a little too much.

Same tires and ratio, are you getting better?

I have been running a Superchips for 50,000 miles +-. I have a homemade boost fooler (air pressure regulater set to 20psi between MAP and intake manifold).

My observations are this.

Smoother accelleration and lower WOT or loaded EGT's when set to Hi-Perf as compared to Perf-Tow.

I verified this this weekend pulling two jeeps on a 24' flatbed from Houston to Del Rio.

I had programmed back to Perf-Tow because I am getting more smoke at low boost levels that before and was trying to diagnose the problem.

From Houston to Castroville I had to drive by the Pyrometer as EGT's would exceed 1300 pulling hills at 70 and 75 mph. The truck was pulling fine with this familiar load but EGT's were not normal.

At a the first fuel stop (200 miles 28 gals, not normal) I reprogrammed back to Hi-Perf. EGT's would not get over 1250 no matter how hard I pushed it. I delivered the jeeps 190 miles further and proceeded to 415 miles before refueling with 29 gal.

I figure my black smoke problem is probably the regulator (boost fooler) not actuating properly so the ECM is adding fuel because it is seeing low boost pressures. I am planning on pulling it and checking calibration or giving in and purchasing a real boost fooler.

OBTW: This boost fooler has seen over 100K mile on two different trucks.

This is almost opposite what SuperChips recommends. Are you supposed to use a superchips with an ETH engine? #3705? I would think this was for the

ISB only. huh...



what made you think you needed a boost fooler if you have a superchips? Did you see the error codes? others on this thread say the superchips will handle the overboost signal.



Black smoke on max setting is normal with superchips. They are cramming in even more fuel and timing hence the very explicit warning not to do any towing when set at max setting. Not even heavy tool boxes.



I was hoping to increase boost from 20 to 30 lbs to force in more air to help cool down temps and to supply extra oxygen to help combustion and hopefully lessen black smoke caused by the SuperChips rich fueling.



You didn't mention how you increased boost?

 

[Huntmastr1]

I don't remember when I purchased my superchips. It was when they first came out for our trucks though. EDIT:I purchased my #3705 in August 2003.

I called Superchips and verified that the unit available would be applicable for my HO as the distributor that I was making a group purchase from had said it was not. There are 1 year old post on this, search superchips or my handle.

Superchips assured me that it was applicable and they also told me that the programming had no provision for modifying the boost signals. I trusted them and installed my boost fooler and boost elbow.

The reason they will warn against towing with any setting other than Tow-Safe is because the programming can and will cause high EGT's if not controlled by higher boost, larger exhaust, higher flow intake. It can also cause drive train failures in stock setup. I can slip my clutch pretty easily if loaded with out the RPM's. You know some folks have been know to pour on the Bombs without gauges too

As I stated I have been running this programming for around 50K miles and the low boost acceleration black smoke I am seeing is new as of the last 5K miles. I am getting 28 to 29 psi of boost on WOT runs



Are the current programmers any different? I haven't been here browsing in awhile and trying to catch up



My truck has 149K miles on it today!

 

[Dave Ratcliffe]

I'm currently running the Hypertech Programmer. I tried the Superchips 3705 about a year ago and sent it back because it made my truck run hot (+1300 empty) and smoked like a coal train. I've used a BD boost fooler with both.



The Hypertech programmer smokes less and I can only get it to 1200 degrees empty. It gives me another couple of pounds of max boost over the Superchips. I am getting an ECM fueling code with the Hypertech, but the truck runs really smooth. If I go to the dealer, I'll just clear the code and return it to stock programming. One thing I like about the Hypertech is it doesn't have the stumble that the EZ box gave me when the engine was not completely warmed up. Less agressive timing perhaps?



For what its worth, I've tried stacking the Hypertech with an EZ box and I didn't notice any power difference and max boost numbers were the same.

 

[RobertMiller1]

yeah, it is easy to get an answer and hard to get the right one. Somewhere on this thread is someone running 30psi and the Superchips and not generating overboost command.



so I am going to try it without external boost fooler. failing that, i will reset codes, and get a boost fooler.



I only have black smoke at load or full throttle blasts.

 

[jpmutt]

I am getting a steady 18 mpg. I really am happy with the Hypertech programmer so far. As stated earlier, I am getting the overboost code and the Ecm fueling calibration error code. I have noticed the engine stumble worse when cold but this truck has always kind of done that. I am anxious to try a set of injectors and a FASS system. I can't get the pyro over 800 even when towing the race car at 85 on I-25. Keep in mind that the probe is post turbo and I have straight 4" exhaust. I have a boost elbow and have reached almost 28 psi.

 

[dragrcr1005]

i also had a po602 code that popped up after my truck stalled while idling. the truck would not restart unless i held my foot half way to the floor. it smoked like a freight train and then died. i bleed the water seperater and the truck fired up and ran rough but then smoothed out and ran fine. i scanned for codes a few days later and found the code. i have a superchip, like the hypertech, i wonder if this code comes as a result of the programmers???

 

[TurboDog]

RobertMiller- I have been running the Hypertech with my setup for months now, with only a boost/bleed air elbow at the wastegate, no boost fooler at the MAP sensor. Truck runs great, and even with hitting 28 lbs of boost daily, it rarely ever sets off the check engine light, and that usually clears itself after a few days. I do see the over boost code when I check for codes with the hypertech, but it does not seem to affect anything other than the check engine light from time to time.

 

[KKunz]

You should not get a over boost code if your running 30 psi of boost or less, any thing over 30 will set the code and put the engine in protection mode.

 

[TurboDog]

Maybe 30 on some, but on my 1999, anything over 20 sets the code, but does not always set the check engine light. I have checked my codes after having cleared them, and then taken a test drive to get boost over twenty, then checked them again, and the code was there. Also checked it and it is not there if I keep it under 20 lbs of boost.

 

[dacook]

Now ya'll got me intrested, does the higher psi result in MORE power or does it just cool egt's down? I too enjoy the hypertech, 1250*f is all I can muster at WOT empty.

any one pull a load with the hypertech on level 3?
