I just paid for a Hypertech 121322 should be shipped soon. Is this a chip that is just plug and play or do I need anything else with it? Has anyone noticed a gain with this chip? Thank you

 

I cant believe no one has any info about this chip.

 

I used to have this chip, is it the piggyback version or did you get the whole prom chip? Anyway, a 160 degree thermostat is required cause now your driver's side fan (main fan) is programmed to come on at 176 degrees. Timing is increased a little at WOT too, torque converter will lock up a later than stock, fuel is leaned out a little at WOT also. I think you may feel a slight gain if your car is stock,but i feel this is mainly due to the torque converter settings.

 

I do have headers and full exhaust done no a.i.r. pump and no cats

 

with no air,there should be a small change done in the chip,but u should be alright. With headers i would say that richening up the mixture would give u better results.

 

what do you think it will feel like with the chip 10 to 15 percent gain?

 

nah,it really just changes how the car "acts". Throttle response ,etc. Like I said before the biggest gain from it is prob just from the torque converter settings

 

ok so it will just drive better that sounds good to me.

 

make sure to place in ECU correctly not 180 deg out. Also may want to disconnect battery as a precaution. Enjoy the added power.

 

i recieved the chips today there were 2 chips they are the ones that are complete but why 2 and do i put them both in or are they different with different tunes.

 

What do you mean by 180 deg out this is my first time putting a chip in any vehicle.

 

2 chips? u shure you didnt get an eprom chip and a piggyback adapter?

 

Hold the ecm in your hands,the harness of your ecm should be on your right on the ecm.Access door on the left side. If u have the white style of the Hypertech(all in one unit) then look inside it through the windows in the top, u should see a label with writing on it(part #'s) that is the actual eprom(chip) that part should be facing up when u install the whole thing into your ecm. Look at my next pic of an ecm.

 

look at those pics, which style did u get?

 

Pic of an ecm

 

I got 2 of the one on the left.

 

the green one

 

ok, so 2 eproms and 1 green piggyback adapter?

 

You should have got a chip from him http://www.tpichips.com/ he does tbi and tpi chips

 

where did u buy your hypertech from?

 

I got it from a tgo member he hasnt been on here for a few days. they both look the same as the pic on the left one has a white sticker on it that says hypertech and the part number the other one is missing the sticker. both say hypertech on the green part.

 

ok ecm is laying on my floor I plugged the original prom into the hypertech chip then put it in the ecm it only went one way. Car starts and runs. This was very easy but still wondering about the second chip. Was I supposed to put the 2 chips together then put it in the ecm? I cant drive my car till I get my throttle cable I only have 2 strands left on my original cable I dont want to hurt my car from it be stretched and frayed. I ordered 2 cables because there are very few left at the dealer and seems like nobody else is making cable for tpi cars.

 

not sure what u mean. You wanna insert the small black eprom into the green adapter and then take your stock chip and plug that into the green adapter also. Make sure they are both facing the proper directions.That picture shows the stock chip with its blue plastic cover removed.Note the direction of both eprom chips. They both face forward.The hypertech is just the small black eprom chip shown on the bottom of the picture ,you need to use your stock chip also to run the car,

 

If u have another eprom that the guy sold u, you need to contact him and find out what is on it. Unless you have the means to read the bin.

 

So I did it right now, I have to find out what is the deal with the other chip. I have no way to read the chip. But maybe the guy that i got it from will respond back.

 

I've compared the hypertech programs to stock chips. The only difference I can see is minor fuel and spark changes in mid-range RPM and lower fan turn on temperature. Neither of which do much of any thing and will in fact lower your MPG. In my opinion, The piggyback adapters are not great for long term use. Are you sure that the programming on the chip is for your car and motor?

 

let me know how you like it

 

Util;ity: I forgot something about the HYper. Mine was stage two or whatever it is called. When i installed I noticed the instruction said to move the initial timing from 6 to 10. That tells me the SA for WOT is achieved with a wrench and timing light. So the fueling change is all that is in chip plus it may in fact pull SA in midrage to avoid det due to added SA mechanically.

 

Right. I believe that is exactly what it does. adds 4* across the entire spark table but pulls some in mid-range to prevent detonation. Provides a little more power at the expense of mileage and overall smoothness. For TPI they have the 122321 street runner and 122322 thermo master which requires a 160 thermostat which I believe is completely wrong for an engine designed to run around 210 degrees.

 

no,stg2 hypertech spark table is exactly the same as a stock AUJP til u get to 90-100 kpa. It then adds like 3 degrees of timing there(WOT). the VE table is the same deal,but it actually gets leaner in the 90-100map ares. Fan temps and TC settings are different and the target A/F ratios at like 4k rpm and above are richened.
