Basically just need to know what mods will keep VCT and what ones will not.
I have a microtech LTX-12 at the moment, got it cheap and wasn't concerned about VCT at the time so didn't research it. It's a plugin for an RB25DET, does this ECU support VCT? From searching I can't find anything that says it does, so I'm guessing it doesn't.
Now if I'm right that it doesn't support VCT, I might be looking at a new ECU (depending on how happy I am with my next tune after next mods). So far I like the look of the new Haltech Platinum range as well as the Vipec V88 or Link G4. I will have a speak to my tuner about which of these he thinks is the best option, but need some feedback here about the haltech platinum pro range for R32/R33's. Basically, because I had a microtech, and thus no longer have the stadard ECU, AFM, loom and whatever other sensors that have been replaced, will this cheaper plugin option still be worth it? I don't want to run an AFM, and i know the ECU does support MAP sensors as well as MAF, but would I be better off going with the Platinum Sport 2000 for the extra money considering my already hacked loom and no AFM's etc? Does the Sport 2000 support VCT, I know it supports VTEC, but not being a plugin for an RB25DET would this cause problems or would it simply be a matter of my tuner enabling VCT control and adjusting when it comes on and switches off?
Ok now the next thing - Cams. I know that you can only use an exh adjustable cam wheel as an intake one will not allow VCT to work, but what about drop in cams? Tomei poncams are the cheapest so I'd be looking at some 256 duration and 8.5 lift exh and intake. I've noticed HKS sell their exh and intake cams seperate, besides the reason of countering intake/exhaust flow balance is this also because an intake cam will not allow for VCT to function? I'll only be looking at cams if I can't get the power I want without them, since my goal is 280rw/kw with as much response as possible.
