Question JC Sports Torque Chip II

What exactly is a "torque Chip"? Is this the same as the voltage clamp for the MAP cars? Why is it called a torque chip?

The torque chip II (TCII) is not just the voltage clamp for turbo's cars with MAP sensor, but it does come with and without the clamp.

It increases fuel delivery for modified cars in a variety of ways, but also is supposed to benefit unmodified cars. I don't understand how it works (electrical engineering is a puzzle to me), but have been told what it does. It is very clever.

(1) First it enriches about 6% across the board but can lean out when needed, works with any year model (manual or auto tranny), and allows the ECU to train faster for the best air/fuel and acceleration (about 1 week for best results, but still helps right away).

(2) It has two possible outputs/wires for fooling the ECU into thinking the engine is approx 5% or 10% colder (depends on which wire), so it will enrichen more or less dependent on engine temps.

(3) It follows the car's acceleration (rpm vs time) and adjusts the air/fuel mixture for optimal acceleration like when the engine is free reving. This like a built in road dyno maybe? It helps the ECU remember these fuel requirements for future use.

(4) It eliminates or over-rides the ECU's limiting the acceleration experienced in back-to-back full acceleration runs.

It definitely works better with my MY00 turbo than when I had an AFC. I still had to tune the fuel pressure for different amounts of boost, but the car at 5 psi and an untrained ECU with TCII (with and without using the electronic boost controller) was faster than when I had played with the AFC settings for three months!

Made so much power 2nd gear blew up at 9 psi... :-( See post entitled "9 psi boost + MY00 5-speed tranny = Bad Mojo -> No Go"

Larry

PS: Whomever says an IHI RB5 turbo doesn't allow you to make more than 230 hp is just dead wrong. This car is at least 250 at the crank and 200 at the wheels at 9 psi with everything we've done. Flame on

Hmm. Yeah... got smoked by a '95 Legend tonight. I got him so bad off the line I only part-throttled it through 1st gear but then he stepped on it and after my 1-2 shift he went flying by... Where do I pick up this TCII? I want more power w/o going turbo just yet.

Thumbs up

Thanks for the info Larry! I am about to purchase my IHI kit from JC Sports. I hope it comes with the TC2! If it doesn't, I'll be sure to add it to my kit.......

Still people are saying these chips are nothing more than a voltage clamp! Only the people who are running these chips understand how much of a difference they make, especially the NEW TC2!(retails for $325 and I bet NO-ONE can reproduce this chip...do I hear any bets?)

How would this TC2 effect a MY01 with headers, exhaust, cams and pulley? Would it be worth it?

Question

Kevin, why do you sometimes use a personal screen name instead of the JC Sports one? Just a little worried that it may mislead some people.

How do you think a car with a TCII would stand up to a car with a TEC II ?

How about some photos of the chip and what lines it intercepts to the ECU. So far I get that it set max voltage to 4.85 (or can) and can go limited fuel enrichment (less than a AFC can) plus somehow smooths out the spikes on various inputs to the ECU (the prevent retard on multiple WOT runs?)
just some guesses. Do you guys really know what this one does this time, or it it pay and pray still? Think you'd have more people interested if you had more detail and less snake oil.

I'm very curious as to what it does also. I'd be interested in buying one if the price went below $200 and someone freakin' knew what it actually does.

Thanks - Jon

Hey Larry, do you have the wiring diagram that comes with the TC2? I am so curious what this thing actually does.

For those that are planning on turbocharging your MY00+ (me) I would like to let it be known that JC Sports is no longer selling their basic "boost chip" and they now ONLY sell their $350 TC II. There goes the minimal piggy-back route eh?

OK, we've dropped the price to $250 for the Torque chip 2.

Snapperhead, the chip will benefit any 90-95 Auto and Manual Subarus and 90-2002 manual Subarus.

Ridinlow, I post under my personal name when offering my opinion. I dont feel it would be professional to state a personal opinion under the JCS name.

Niloc, The chip does nowhere near the engine management that the TEC2 does so it would not be fair to compare them in the same category.

Midwayman, we've explained numerous times that the chip is made for us exclusively by a fellow who takes quite a bit of pride in keeping his electronic skills secret(he guarantees that the chip cannot be duplicated by anyone!) However, Larry may be able to give you a more detailed description as to what its doing to improve his cars performance.

Jagcars26, Yes, we have/had numerous customer service problems, but we are also learning from our mistakes.

STIShawn, Ill ask the guy who makes the chips if it will cure the lean problem (Im assuming it will since Larry got rid of his S-AFC)

Hope I didnt miss anyone...Kevin

I know the guy wants to keep his chip secret, but if he's so sure nobody can copy it, whats the harm of telling us exactly what it does. I mean we dont need part numbers, just what function on what line, at what RPMs. What settings if any, and a wiring diagram. That would be enough to let people make a more informed decision.

what I was wondering is if this chip could do anything that a TEC II can't?

is that a joke??
they are not comparable..
2k vs 250 is a big price diff..
the TEC II replaces all fuel /ignition functions of the engine..
If you dont do Shiv's parallel system, it replaces your entire ECU..
the torque chip is a bandaid.
I am not passing any judgement on it, just saying it is an add-on to "fix" the ecu...
any add on is a band aid. The more band aids you have and try to tune together, the more a complete engine management solution is needed.

The chip is not just a band-aid it re-trains the stock ECU to adjust according to boost and fuel.

I just talked to John at JC sports about these "chips". It is installed in the wiring harness, not to the ECU, it is emmisions complient (not CARB certified however), needs to be soldered into the harness and you must have an appropriate year wiring schematic. The Torque Chip one is a 4 wire affair and better for NA applications. The Torque chip two is for for turbo applications and is a 10 wire deal. The TC1's are in stock and the TC2's are a week out. Overall rather intersting. Might have to do this come spring or summer. Hopefully quicker delivery than the Turbo GB as they have them in stock.
NOTE: Im not slammin' JC Sports here, just a comment.
