Glad you like it leadfoot. Did you do an ECU reset? If you think the gains are impressive this soon, wait until you reset and let the F/A and timing adjust to the new flow. I was disappointed at first with mine, but the reset really wakes it up, and then as it learns, it gets even better.

A word of caution. The car will not know how to deal with extreme loads right after reset since the flow is so different from the factory settings, so ease into it instead of just WOT right away. Run through the gears up to 4-5K first a few times, then run through again to redline, then put in D and punch it. You will be shocked.

Word has it that the final mod should be the Technosquare reflash customized to your setup. If you live in SoCal, then drive over to see Tadashi, he will set you up. If not, call and tell him what you have installed. There is probably a map saved that will drop right in.

 

By the way, what tires are those. Exotic tread pattern.

 

Oh sorry,

I see you already have the reflash. Way ahead of me. Enjoy!

Look's like Falken Azenis sports, awesome tire, but VERY limited size range. I'd have them on my car if they make them in a useable 18" size.

Gsedan35 got it right. They're Falken Azenis. I bought them specifically for autocross. They're the tires that most people who don't have race rubber or their stock tires buy. Fairly inexpensive and very grippy. Only limited sizes though and their biggest is 245/45/17's which I have tightly squeezed on to our stock 17x7 rims. Most tire places wouldn't recommend the fit, but will mount them for you anyway.

i have a question! Do you know how big the diameter is the pipe right after the cat to the stillen exhaust? Thanks!!

 

The Stillen pipe diameter is 2.5" The pipe diameter out of the cats is 2.25" My custom system run's 2.5" off of the headers into the highflow cars and 2.5" for the rest of the system.

lead_foot,

If you don't mind, where did you purchase your exhaust and how much did you spend?

Thanks,

I got it direct from Stillen and with shipping it was right around 1k.

Holy crap, I can't believe what a moron I was. I completely forgot to do the ECU reset. I did it last night and took it pretty easy on my way to work this morning. On my way home I nearly snapped my head off. Wow, what a difference. I was going to do the reset when I got home from the install on Friday, but it totally slipped my mind. The worst part about it was that I had an autocross this weekend and I could have totally used the extra power.

Learn from my mistake folks. If you do this or any other mods, don't forget the reset!

Next I'll be calling the guys at Technosquare to see if they've had anyone come through with a similar setup as mine so I might do a reflash. We'll see.

Yes, I waited for a few days to reset after putting the Stillen DE on too. After reset, I made the mistake of just punching it right away on the first available onramp. The car just did nothing for about 3 seconds, no response at all to the throttle, then WHAM, it just took off like mad and reved up so fast that it tripped the rev limiter before it could shift itself. It didnt know how to deal with the combination of crawford, UR pulleys, K/N, and stillen. Too much, too fast. I can only imagine how fast this car will be when the custom TS ECU flash tunes it all.

 

Good job!!! Very clean look and lovely sound!!!
Sorry Coupe!!! We are on!

 

Sweeeeeeeeeeeeeeeeeeeeeeeeeeeet!

 

In addition to the "Basic ECU Reset", you may also be advised after major intake/exhaust mods to do the following "Accelerator Pedal Released Position Learning", "Throttle Valve Closed Position Learning" and "Idle Air Volume Learning" resets as well.


ECU Resetting Procedures

NOTE: Please read all instructions and be familiar with them before any attempts. Timing is extremely critical. If it is not done within the specified time, the ECU will not reset and the Check Engine Light (CEL) will continue to remain ON. A stopwatch or an analog clock with a second’s hand is mandatory.


Basic ECU Reset (from http://www.technosquareinc.com/350reset.htm)

Operation Procedure:
1. Confirm that accelerator pedal is fully released, turn ignition switch “ON” (NOT start) and wait 3 seconds.
2. Repeat the following steps (2a and 2b) procedures quickly five times within 5 seconds.
2a. Fully depress the accelerator pedal (HARD).
2b. Fully release the accelerator pedal.
3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the CEL starts blinking.
4. Fully release the accelerator pedal (while the CEL is still blinking)
5. Wait about 10 seconds.
6. Fully depress the accelerator pedal and keep it for more than 10 seconds.
7. Fully release the accelerator pedal (The CEL light will continue to blink).
8. Turn ignition switch to “OFF” position and now you can start the car. The CEL light should be gone. If the CEL light continues to remain ON, repeat the above steps. Remember, accurate timing is EXTREMELY critical to resetting the ECU. You may even need someone's help to do this correctly.


Accelerator Pedal Released Position Learning

Description:
Accelerator Pedal Released Position Learning is an operation to learn the fully released position of the accelerator pedal by monitoring the accelerator pedal position sensor output signal. It must be performed each time harness connector of accelerator pedal position sensor or ECM is disconnected.

Operation Procedure:
1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch ON and wait at least 2 seconds.
3. Turn ignition switch OFF and wait at least 10 seconds.
4. Turn ignition switch ON and wait at least 2 seconds.
5. Turn ignition switch OFF and wait at least 10 seconds.


Throttle Valve Closed Position Learning

Description:
Throttle Valve Closed Position Learning is an operation to learn the fully closed position of the throttle valve by monitoring the throttle position sensor output signal. It must be performed each time harness connector of electric throttle control actuator or ECM is disconnected.

Operation Procedure:
1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
Make sure that throttle valve moves during above 10 seconds by confirming the operating sound.


Idle Air Volume Learning

Description:
Idle Air Volume Learning is an operation to learn the idle air volume that keeps each engine within the specific range. It must be performed each time electric throttle control actuator or ECM is replaced, or if idle speed or ignition timing is out of specification.

Preparation:
Before performing Idle Air Volume Learning, make sure that all of the following conditions are satisfied. Learning will be cancelled if any of the following conditions are missed for even a moment.

- Battery voltage: More than 12.9V (At idle)
- Engine coolant temperature: 70 - 100 Degrees C (158 – 212 Degrees F)
- PNP switch: ON (Park/Neutral safety switch - AT only, MT fully depress clutch)
- Electric load switch: OFF (Air conditioner, rear window defogger, headlamps. Note: on vehicles equipped with daytime light systems, if the parking brake is applied before the engine is started, the headlamps will not be illuminated.)
- Steering wheel: Neutral (Straight-ahead position)
- Vehicle speed: Stopped
- Transmission: Warmed-up (For A/T models, drive vehicle for 10 minutes.)

Operation Procedure:
1. Perform "Accelerator Pedal Released Position Learning"
2. Perform "Throttle Valve Closed Position Learning"
3. Start engine and warm it up to normal operating temperature.
4. Check that all items listed under the topic PREPARATION (previously mentioned) are in good order.
5. Turn ignition switch OFF and wait at least 10 seconds.
6. Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.
7. Repeat the following procedure quickly five times within 5 seconds:
7a. Fully depress the accelerator pedal.
7b. Fully release the accelerator pedal.
8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the MIL stops blinking and turned ON.
9. Fully release the accelerator pedal within 3 seconds after the MIL turned ON.
10. Start engine and let it idle.
11. Wait 20 seconds.
12. Rev up the engine two or three times and make sure that idle speed and ignition timing are within the specifications:

Idle speed A/T: 650rpm, + or - 50 rpm (in P or N position)
Idle speed M/T: 650rpm, + or - 50 rpm (in N position)
Ignition timing A/T: 15 Degrees BTDC, + or – 5 Degrees BTDC (in P or N position)
Ignition timing M/T: 15 Degrees BTDC, + or – 5 Degrees BTDC (in N position)

13. If idle speed and ignition timing are not within the specification, Idle Air Volume Learning will not be carried out successfully. If idle speed and ignition timing are within the specification and Idle Air Volume Learning cannot be performed successfully, find the cause of the incident by referring to the following Diagnostic Procedure:

1. Check that throttle valve is fully closed.
2. Check PCV valve operation.
3. Check that downstream of throttle valve is free from air leakage.
4. When the above three items check out OK, engine component parts and their installation condition are questionable.
5. If any of the following conditions occur after the engine has started, eliminate the cause of the incident and perform Idle Air Volume Learning all over again:

- Engine stalls.
- Erroneous idle.

My engine stall at the time of the idle air volume learning ... not sure whatit is - but my timigns are of course are not within specs (TS ECU).
