ok, one step closer to my goal. i have everything planned out but have run into some problems. heres my list of ish
rebuild bottom end - scheduled, bergenholtz racing / golden eagle
ignition timing - done, j&s safeguard
fuel curve - done, v-afc
injectors - upgraded but will be swapped out later
fuel delivery - upgraded but will be swapped out later
speed govenor (did we even have one??) - removed, mugen ecu
rev limit - adjustable, mugen ecu and accel ignition
launch rev control - ?????
WOT shift rev control - ?????
air/fuel meter - done, j&s safeguard
egt - coming, autometer
vtec engagment point - done, v-afc
ignition system - done, accel 300+
cam timing - done, aem adjustable gears
head - leaving stock for now
valvetrain - leaving stock for now
safty factor - done, J&S safeguard
now as u can see my problem arises in trying to find something that can control those rev points. if ur unclear what i meant those two points are a rev limit that works when ur not moving and the clutch is in and a rev limit that works when u speed shift (shift staying at WOT). i was originally going to get a hondata engine management system but my plans fell through so i work with what ive got now. i bought the J&S and decided i dont need a standalone or piggyback ecu. so i guess my question is do u guys know of anything i can use to control those two rev points short of a new management system?? (the msd module doesnt plug into my igniion)
also if i overlooked anything engine related that i need to upgrade please let me know. i think this is all i will need to tune and run the car at 20+ lbs of boost
TIA

Check out Hondata and Zdyne. Both of em are programmable ECU's based on the stock one and they plug into your stock wiring. They both have the rev limits you're looking for, and they'll also replace the V-AFC, Mugen ECU, and J&S Safeguard. They have fully programmable fuel curves (much more precise than the V-AFC), adjustable spark timing, rev limits, A/C compressor control, and a buncha other stuff.

Fullbuild D16y7 (bleveit) 1.6sohcnonvtec
small shot NOS
13.50@102 on streettyres
12.93@110 on slicks (yes, bigger shot that time OK yeah yeah)
hmmm..im getting a PR8 ecu with the mugen program on it. would getting a V-AFC be pointless? i still want to change the vtec engagement. does the fields controller just do that?
In order to run 20+ psi of boost, you will need a piggyback or standlone system. The J&S Safeguard works based on how much your motor knocks. Also you will need an aftermarket MAP sensor to handle the high amount of psi. The OEM MAP's diaphram can only tolerate up to 12 psi before it breaks. Thus many standalones utilize a GM 2 bar (can handle up to 14 psi.....reason it's 2 bar is because it includes our atmosphere) and 3 bar (28 psi). Also, you will need at least 720cc injectors in which the Honda ecu will not be able to handle. Alot of sources say 310cc is the upper limit for the stock ecu. As for a 2-stage rev limiter, check out MSD's 2-step control. I know you already have a thundersport so I won't recommend the Digital-6 which includes the 2-step limiter unless you want to replace your ignition amp altogether. Also, don't forget you're going to need a pretty strong clutch. At least a 6-puck or maybe a 4-puck if you're planning on making that much power.
Malice, it wouldn't be pointless. Although you still won't be able to fine-tune the ignition.

I forogt to mention you will need a very strong fuel pump. The fuel pump I saw you had would not probably handle this much power. Alot of guys like to use the Paxton in-line blue pump which supports in excess of 750+ hp. It's also a good idea to upgrade your fuel lines to 3/8" or maybe even 1/2". 3/8" is similar to a -6 AN fitting and -8 for the 1/2". -6 is the size often used by V8 guys for their lines. Along with this you will need high flow fuel filter. Again, people like to use Paxton or the like. Whatever accepts -6 or anything bigger. Honda fuel filters have been known to handle up to 400+hp but after that I would ditch it for a bigger one. Then, Paxton makes a regulator that accepts -10 lines. Personally I am going to run a -10 S/X regulator that features a -6 return line. Either you can modify the stock fuel rail to accept these fittings, or buy an aftermarket one like a vortech or str that has 1/2" openings on each end.
If you arent going to go with the hondata, accel has a new add on ignition controller/sequential limiter that also does some other stuff, like maybe timing retard? I forget the specifics, but I saw it in a black and white ad in the back of the most recent super street. I went to their website, but I couldnt find it. The kit is a separate controller that plugs right into the existing 300+ harness and has a remote control (wired) for the adjustments. I think itr runs about 200 or so. Check super street for the link, its in the ad
damit, u know how hard it is trying to find accurate info on the fuel delivery system
ok so the ecu will not be able to handle the larger injectors, i could add extra injectors and a rebic but that will cost more than a standalone unit. so my only option is to get a new management unit??
hmmm, ok i have read about ever article ever written about injectors and fuel pressure and fuel flow etc... but stiil dont understand "exactly" how a rising rate regulator plays into. i know how the regulator works and what it does etc. this will raise the fuel prssure level which allows the injectors to flow more fuel blahblahblah. can someone explain this in detail??
grrrrrrr, ok i give up
nobody knows anything about this high end performance crap
not talking about the board, im talking most shops and any internet site i have looked at
i cant talk to haltech directly (thats the system im looking at now)
oh well, rebuild isnt coming up immediatly so i have time to fix it
