With the recent issues to do with the bad computer boxes, I made an enquiry with my supplier. He tells me that my S/C kit is almost ready to ship BUT they are waiting to get the "new" computer boxes before sending. Does anyone know exactly what was wrong with the old ones and how the new ones have been modified?

VortechS2k, as you are with the company, can you comment on this please?

 

Is this a second revision of the electronics?
The first was the box with the incorrect wiring coming out of it.
I did a swap for this a long time ago. I'd hate to have to swap again, since mine is being installed at this very moment. I'll know if it doesn't work tomorrow...

I'm not sure. That's what I was hoping to find out by posting this. If you search "vortech" and check threads from the last week, there have been at least 3 threads where there have been references to bad computer boxes. And replacement ones were in short supply.

 

yep, apparently vortech was able find a fix for the first batch of the defective timing boxes. but, from what i was told they are now unable to duplicate the revised versions. im still waiting on my new box.. vortech does not produce the boxes so who knows how long it will take.

 

Update: My timing control box is working fine after being installed today. I haven't driven it but the shop did a quick dyno run to check the AF and boost and everything seems fine. This box is one I got on 8/1 to replace the wrong one shipped with the first few Vortech SC kits in august.

Is this with or without a vafc? And when you say "fine", does that mean the thing isn't running lean like some have reported lately?

 

Yes they said it isn't running too lean. I think boost was about 6.5 psi. I just have the vortech kit, no mods (other than a Mugen exhaust), no vafc. I'll check out the dyno plots tomorrow. They did a before and after dyno so I can see how much the AF ratio changed.

Great news. It's like a roller coaster ride, here. Going from discouraged to a bit more upbeat now. Please keep us informed. I'd just love to hear for once that somebody just bolted this thing on and drove into the sunset without a glitch.

Great news.

 

Update, Update:

Too soon for a thumbs up. My second timing control box is in fact defective in exactly the same way as a few others. So it looks like I'll need a third box.
It ran fine on the dyno, but while idling in the shop a check engine light came on. We dumped the code and it was related to the TDC sensor. If you try to run without clearing this code the car won't rev past 3000 rpm. So I had them yank the box and I'm sending it back to Vortech. The car can be driven on the stock ecu if you don't go over 4000 rpm, which is just enough revs for safe highway driving, about 70 mph. Driving at 3000rpm with a fuel cut would have been a nightmare.

It would be nice if I could dispense with their electronics and go with some standard programmable setup. Too bad there's no Unichip with a plug and play harness for the S2000 like there is for the WRX. The Vortech spliced in black box seems to be junk, and you can't tweak the program if it runs lean (though the box has a serial port, who knows what software you need to access it).

PS - Vortech said they don't have any new (um, new new) timing control boxes in yet.
