Hesitation Found: Ecu Crush Mod Really Works
I had some spare time tonight wile waiting for the paint on my wiper arms to dry, so I got on the Mitchell and looked up TSB's on hesitation and there it was right on the screen, I couldn't belive it. I had always thought the ECU crush mod was a hack fix, I didn't know it was an acctual factory TSB. So I had the directions and a nice pic of where it was, so I pulled out the ECU and crushed that baby, and on the way home NO MORE FREAKIN HESITATION! Happy Day.
Also disconecting the battery seems to have reset my idle problem after adjusting my TPS. Happy Day indeed.

Check the how-to locker and yahoo locker/archives for the TSB and how to on the crush mod. It's there. But I don't have a 92 so I don't have to do that.

Is this somthing everyone can benefit from? I don't have any noticeable hesitation on my 92 or maybe i do and i'm just so used to it i don't notice it. Any help you can give me subafreak and i'm sure Type O would be proud.

if its a TSB directly from Subaru....
you can usually trust it. An engineer made this happen not some kid in ohio who thought it may be a good idea. If you have a 92, it cant hurt to do it regardless

I'm more than ready to do this, but I'm not sure I understand the issue of Hesitation?
When, where does this occur? I know the car definately hesitates when its cold, but is there something a little more specific? I suppose I could just crush the bugger and see....

Hesitation ?
Yes please, will someone define the hesitation referred to. Is this the rather tardy kick-down response which is annoying when one calls for everything on tap when making an overtaking manoeuvre ? If so an improvement would be welcome.
The component involved in ̉the crushÓ is most certainly not a resistor and is more certain to be a ferrite bead inserted to prevent possible R.F. interference, hence the reference to noise suppression. Just how removing it could cure ̉hesitation Ô is rather intriguing and must have presented a curly problem to the original designer.

standard hesitation
From a dead stop, when you take off
many 92 cars experience a hesitation for a split second before the car actually takes off....... Sometimes the hesitation is also caused by transmission woes when the cars cold but thats a whole different ballgame.....

Trevor, I think its actually an inductor or coil(can't remember what they are called, but opposite of a capacitor), and we can't remove it, we just crush it a little, which I would expect reduces its inductive charactoristics therefore changing some logic decision.
Capacitance/inductance. Anyways, I'll give it a shot, and see where it changes the so called hesitation, maybe everywhere???
