Hesitation Found: Ecu Crush Mod Really Works - Page 8

Pure_Insanity8 · #**106** 09-30-2008, 01:15 AM

I'm not sure how hard these guys found it but I thought it was a PITA to get out when I tried it 8 years ago. The worst part about it was my ECU didn't have the bead... so it was a worthless endeavor.

Anyone know if there was an updated ECU that could have been put in? Mine has a build date of 4/91.

i am now led to believe that it was all random for the 91 build dates.

My ECU had the bead and my cars build date was 10/91

The other thing to consider is that if you are not the original owner, the previous owner may have taken the car to the dealer where it was taken care of earlier.

No. you just need to take your time and dont get too angry.

you will either need a 10mm shallow socket or a long 10mm wrench.

take the bottom one off and just loosen the top 2

Is it just as tedious to get it back in or is it any easier?

much easier

Finally did mine this morning.

I think I might have made it harder than it needed to be, I ended up removing all three bolts because I didn't understand how that was ever going to lift up, after it was off it made more sense, but all the same I'm very pleased with myself. Hopefully it was worth the trouble.

My car was built 05/92 and had the bead on the ECU.

I did mine this afternoon it made a big difference. I had been trying to fix the hesitation for over a year I replaced plugs, fuel filter, air filter, pcv valve, vacuum lines, tested and repositioned the tps, cleaned the throttle body, tested injectors, tested the O2 sensor, pulled all the codes, even replaced the valve cover gaskets (which was a major pain in the a$$). After all that this afternoon at at 2:12 HST I started the car for the first time after crushing some stupid little black bead in the computer an now the car has no more hesitation THANK GOD!!... (sigh)

Did mine today, build date of 11/91, and it had the bead, after the mod, it was noticeably more responsive, Thanks,
Joe

To bump an old thread. My 92 SVX LSL is a 6/91 build. It has the ROM chip, no tan resistor and the noise suppressor is absent. The loop is there, just not the black bit.

That sucks since mine has a bit of a hesitation when pulling away from a dead stop. It feels like the ECU pulls timing (quite a bit at that) for s split second. I may have to buy the ECUtune kit anyway in order to run 87oct. No sense in running premium since I drive like a granny anyway.

Your hesitation can be more than just the ecu bead crush. I've had significant changes in performance by adjusting the tps to spec, cheching that plugs and wires are still good, and the vehicle has been running the same grade fuel for at least 4 rides in your Svx.

If you order a stage 1 from the ecutune website and include a note in the paypal transaction asking me to send you the aggressive software instead of the 1v5 I will. That software gets better performance and better fuel economy at the same time. The compression in your car is probably low enough for you to run 87 octane with the the "chip" running it's default tune so you won't have to install a switch to run 87 octane.

On the stage1 aggressive software the switch actually makes it run a tune with even better performance but no improvment in fuel economy.

I have a 92 with build date of 12/91 I pulled the ecu out and looked, no hesitation problems just curious, and the tan resister is there but cut, ie it looks like some one took and sniped it so there is no complete circuit but able to put back together if needed. It has a rom chip installed and the noise suppressor is also gone. Loop still there of course.

I just did this on my 94 EG33 that is now in a 97 Legacy Outback and it may have made things worse. I thought I had slight hesitation at between 2-3000 rpm when getting on the gas so I went ahead and crushed that thing. Everything was fine initially then I noticed the hesitation again and thought "huh, it didn't fix it. Lets get an ECUTUNE" Later that day it got really bad and now pretty much struggles when I get on the gas though it is still quite driveable. What else could it be?

This is my ECU:

and this is what I crushed:

Did I mess something up?
