SVX stage one chip
So whats the deal with that chip on motorsports wharehouse. The pic looks like a fuse. If it is as easy as sticking it in like a fuse well sign me up.

Its a circuit bord about 3" x 5" that goes inside the ECU. The hardest part of the install is removing and reinstalling the ecu under the dash.

You do realize it looks like this... right?
http://ecutune.com/images/sub-adaptor-2.jpg But it is pretty easy to install from what I've seen. Sadly they're not in stock right now, ETA TBD. |

chip
yeah, thats kinda what I was afraid of. Do think crushing the little black resistor or capacitor is a good idea if you are allready in there putting in the board or would the new board replace all those parts?
But you know what im talking about, in that pic it looks like a fuse.

If you've got the ECU open anyway and that thing is there, then yes, crushing it is a good idea. Just make sure you're incredibly careful about it.
Besides, if your ECU is like mine then to use the Stage 1 chip you'd have to remove a resistor anyway. May as well fininsh up modding the thing, right? |

Pic
No, I had no idea what it looked like. Thats a good pic. Anyone here have it installed?

Ecu
So different model SVX's have different ECU's

Yeah. The 91 ECU doesn't have that bead thing to crush from what I remember. The 92-95 do (I think?). The 96-97 ECUs are OBDII so ECUtune Stage 1 won't work with them anyway.

ecu
did you crush the bead/ resistor when you put in the ecu1.5 did it change your mileage?

The Bead Thing.
As a matter of interest, the “thing“ which is crushed is a ferrite bead. In simple terms, it is a sleeve/bead of ferrite (iron oxide), which is arranged to surround a conductor, so as to form an inductor.
A common application involves chocking/blocking the the passage of high frequency interference within a circuit. Crushing the bead, therefore does not affect affect the continuity of a protected circuit. My wild guess is that, in the instance of the SVX ECU, possibly some lower frequencies are inadvertently blocked, thus affecting a time delay function.

For my installation, I didn't have to crush the bead or cut the resistor off as that had been done by the dealership long before I purchased my SVX. They installed their own additonal chip (which is shown in the second picture I uploaded) that I had to remove to install the ECUTune circuit. So I never had an acceleration issue.. it was always a slow and steady pace (which was a tad scary for those short on-ramps to the highway). My car still accelerates at a smooth pace but now I get a faster response (and safer) for reaching highway speeds when entering the on-ramp. My engine also sounds.. deeper, is the best way I can put it (maybe throatier?). I think my mileage has stayed the same... but then I may be guilty of flooring it more often now. So overall I feel it was a good decision for my car. I did watch Ray (halistan) & Kuo (kuoh3) perform the bead crush on Ray's SVX several years ago and I will say, that alone made a difference in his car's get up and go. Aredubjay can verify this as he test drove Ray's car at the 10th Anniversary meet and it was the first "mod" I ever heard Randy say, he was going to do.
