• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Have everything apart but the 2 wire harnesses Supposed to push something while turning something. Can someone guide me through this step. Thank You Richard

It has been a while since I did it, but put your thumb at the bottom of the clip with the slot in it, your index finger at the top, and twist clockwise. I can’t remember if there is something else holding it though. Ignore the marks on the clip. That’s where I was doing my head in, until Peter Aawen gave me the tip.... hopefully someone else will comment if there is still something else holding the plug in.
 
Ahhhhh yes, the locking tab.........that’s the bit I couldn’t remember......thanks Eddie :thumbup:

And THAT's the bit that catches most people!! The tiny little locking clips that're in the middle/top of each connector! :gaah:

So easy once you've found & pressed the locking clip, but boy, it's bleedin' impossible if you don't!! :shocked:
 
If you are, I didn’t know about it when I removed mine and have suffered no ill effects from not doing it, for the 10 days my ECU was away. ssmc. ;)

yes you disconnect it..and leave it disconnected until you reinstall the ECU.

Interesting, 308... I just checked my removal instructions from Jase, and there is no mention of battery removal. I wonder what leaving the battery in situ might impact.

I disconnect the battery for an extra bit of safety.

We're you able to successfully disconnect the ECU and send it off?

Yeah, it is frustrating when someone asks a question, gets replies on how to address the issue and then never responds as to how they went or acknowledges the advice, 308. Just a simple “thanks Eddieshep, that worked” would suffice. :dontknow:

I just removed my ECU and did not disconnect the battery on my new to me Spyder. I don't think it gets power unless the key is turned on. I promise not to do that. I will ship it off in the morning for a Stage 2 flash this time. Having done it before on my grey Spyder, it was a lot easier this time. I could get the top bolt off using my driver. Why I didn't do that last time is a mystery to me. I guess because someone else said it takes an open-end wrench?!

I'm also adding a new K&N air filter to the intake. That plus the modified air box; then I'll do a 15-minute run on idle to let it adjust when I get it back. I'm running the same exhaust I had on the other Spyder. An ELS Crusher with his cat bypass. My only concern is that they say it gets louder with the Stage 2 and it is already borderline too loud. Well, we will see.

I guess I'm not understanding the increased db between the stage 1 and stage 2 flashes? Gotta be the increased sound of the intake with the filter cap being drilled out. That's the only thing letting increased air in > air out.
