rtek makes a good quality tunable ecu.

Rtek7 ECU Upgrade Detailed Information

 

You have a revlimiter... Should be between 7 and 8.5k ish. It might not buzz anymore, but it should still be there! An o2 bung really isnt that diff to get going, and if your doing a plug an play, id throw a wideband in it, so you can see whats going on as your riding around. Any of the upgrades you listed will work just fine, just go with which ever one is easier for you to use/understand.

 

mmm idk i just looked at it and that's a ecu upgrade, i want a stand alone or piggy back so i can use my laptop bro ive been looking every were online

 

If you don't have the budget for a haltech or microtech, build yourself a megasquirt system. You can pick up a used stand alone for around 700$ just have to find someone parting their car out.

And you CAN tune that chip, you just have to buy the next stage up which costs $400. That can be tuned with a hand held or a laptop.

 

i knew the person that used to make plug n play megasquirts for fcs. i used to have one in my old t2, now i run a haltech e6k.
u should look into the rtek 2.0, its great tunable with a pda and comes with base map that runs ur car like factory pretty much.

last person maybe have blocked off the BAC valve, whats ur idle at normally?

 

1000 and some times when its hot its around 1,500 but its sounding like its missing

today i installed a shift lite and got my rear strut bar in maby im gonna ride out to causeway or McDonalds to show all the ricers what a real jdm rotary car is lol

 

lol u may have a vac leak, that idle is really high! 1k isnt bad but 1,500 is too high.
normal rotary idle sounds like it mises anyway.
