I am about to change my ECU from Wolf v500 back to stock in my r33 gtst as i am troubleshooting cold start and running rich issues.

Before I go and do this is there anything in particular I need to do other than simply unplug one and plug the other in? Nothing has been changed in my car when the wolf went in other than a boost solenoid.

id check the wiring loom before you do anything, look for any custom work etc on the loom

if theyve modified the loom (hopefully not) then this could cause issues with the stock ecu

from memory the v500 is plug and play so you should be ok and it should be a direct swap back

but again check the wiring loom near the plug for any wire changes / wiring work

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in?

      Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.

      I would just put EBC back on the "I would not use their stuff" pile and move on.
