Will a programmer take care of..........

[wusthof]

being able to blip the throttle during downshifts? I know it's the drive-by-wire thing. Annoying when you wanna blip, and it take 2 or 3 times b4 the throttle does ~~~~~~~~ TIA

Yes but only in part. What really takes care of that problem is a lightweight flywheel. Ill let you know once mine goes in.

 

[walter]

Also I forgot UD pulleys can help too.

Sometimes I wish I had my SBC back..............I'm tired of this computerized b*ll$hit!!!!!!!!! Walter, are you serious by the part cause is a steel flywheel and factory pullies ?? I can't believe that. Man I'm pi$$ed - any1 else

The programmer will take care of throttle response in terms of fuel ratios and timing adjustments call it a software (PCM) induced response.

Lighter drivetrain components namely the flywheel and pulleys will allow the engine to spin freely by reducing the rotating mass. The engine will do less work trying to spin and put more power to the ground giving you the response you need. That's the hardware part.

Case in point I had a 240SX with a KA24DE engine in it which is a long stroke motor that had plenty of torque and not much horsepower. It also had a cable driven throttle unlike newer engines which are computer controlled throttle and coil on pack ignition designs like my 350Z. I tuned it up nicely with NGK iridiums and wires, matched a nice AEM intake with the header and exhaust. It worked well giving the car a new lease on life at 70K miles but what took the cake was a lightweight flyweel with a sturdy clutch. That plus adding a one piece lightweight driveshaft made it one of the quickest N/A 240's in Houston.

I read somewhere that the stock GT flywheel weighs upward of 30lb maybe even 40. That's a lot of rotating mass spinning. When you step on the clutch the motor just keeps spinning taking forever to stop. Cut the weight and you can heel-toe downshift like a superstar regardless of the tuning.

How big of an effect do you think the light weight flywheel will have on starts when driving on the street? I would imagine it would be easier to kill it if not paying attention.

I had a lightweight flywheel on my old talon, it actually seemed to make street driving easier, although track driving took a bit of getting used to due to the fact you had to hold it at higher rpm than before to launch it. Car was much more responsive and loved to rev out

I hated the throttle on my car when i first bought it. Coming from a cable driven 95GTS, the slow reacting drivebywire made SO mad!

programmer got rid of all the problems. My car blips fine now, and throttle response is great! get a tuner for sure.
apparently everyone says the lightweight flywheel will be better, but I'm perfectly happy with my car now.

Once you get the lightweight flywheel it's a matter of adjusting your clutch slip a little to prevent the car from stalling. On my 240SX (4cyl) I didn't find it that difficult to do, I'm sure with a V8 it should be just fine given the torque. The real problem that can happen with a FW is if you pick out a clutch that is not street friendly. You have to make sure more then ever that the clutch can be slipped and is progressive rather then an ON/OFF switch, in other words you need to opt for a full disk street compound rather then a full racing puck style or sintered iron unit if not you'll spin tires at every takeoff, chatter real bad and make driving in heavy traffic or adverse weather damn near impossible.

This is why I'm taking my sweet time finding the right clutch for the application.

well, I always knew that an al flywheel, UD pullies and an al dshaft will all produce much better throttle response, but yea, I figured the prgrammer would take care of most of the problems. imfamousjim ~~~~~ "I hated the throttle on my car when i first bought it.

sumtimes simpler is better. thank for all the responses guys. This forum is great, not much whoring, and threads don't turn into $hitshows after the 3rd post eg. I bent ur wife over the hood last night! bwahahaha

+1 on Stangnet being an awesome forum.

Now excuse my ignorance but what the heck is a GTS? I thought it was a Mustang GT is there a model I missed somewhere?

GTS was a one year "lightweight" GT for 95. basically just a stripped car (cloth seats, no wing, no foglights, anything power is an option (including ABS, windows, locks, defrost). they had it other years but called it different things.

well actually, it was your wife that said i should get the programmer, haha
