What to do next .

[Sy.]

Hi All .

I know its probably a question that almost everyone asks but what to do next to the ReX ... i am after about 300/350 RWBHP in the end as i think this is enough for normal street use.

What i have so far ... (not alot)
Full through Katimoto exhaust (no cats no silencers)
Possible Chip (not confirmed on paper but rotary guy said it is faster then standard, could just be when it was rebuilt they mapped/tuned it slightly)
HKS air induction.
Blitz BOV (not that it makes any performance gains)

i hear a Power FC is the first thing to get .... comments ?

Im running a full through exhaust
Blitz filters
.9Bar off boost
PFC
Blitz BOV

think thats about it, made 325bhp on the rollers at pips place...

[Sy.]

so best to up the boost by 0.2 bar .. and get a PFC ...
so that would be about 280ish rwbhp ?

Whats a PFC and what does it do?  :confused:

I can\'t stress enough how important it is to get a PFC, I am currently waiting for Reworx to tell me how much my rebuild is going to cost, a rebuild on a car I bought four weeks ago!
The previous owner had it rebuilt only 12 months ago but because he had uprated parts (intercooler, exhaust etc) and was running a stock ECU, it went pop soon after I got it.
If it had benn fitted with a PFC i would be driving a luvverly, 300+rwhp monster right now, instead, I am driving a 1.5 diesel van and desperately trying to figure out ways of making extra cash!
Definately go for a PFC and if you want solid reliable power, get it ported while you\'re at it.

MIne was rebuilt 2000 miles ago .. (by previous owner) so it should be ok ... but sounds like the PFC is the way to go ... how much are they ?
Ada7 .. its a power Fuel Commander i think .. but not 100% on what it does .. or what it can tell me .

[dandan]

Its costing me about £550 i think from Reworx, dont quote me on that though! needs to be setup by a specialist too which costs a few quid

The Apexi Power FC is a programmable replacement for the stock ECU.  There are other replacement ECUs but the Apexi is the most popular in the UK and there are several who can tune these for you - by hooking up a laptop running the tuning software Datalogit they can download a map and then tweak for your specific car.

The commander - this is a small display with buttons and a cable that connects to the Apexi Power FC.  The commander allows you to monitor many items that the Apexi sees - boost, revs, various temps, voltage etc.  You can also program the Apexi Power FC via the commander but very laborious. Many mount the commander on the dash, the R-Magic commander holder is the most popular mount.

Ada - PFC is the Apexi ECU. The PFC commander is a kinda \'T\' shaped Gameboy thing that you can map it with (although it has limited options, and a very slow process mapping with it). Its vital to have somthing like this to change the amount of fuel is pupmed in at what rpm and change the timing. Its also like 15 gauges in one, it can display rev, water temp, airtemp, speed, knock etc...

The datalogit (which isn\'t made by Apexi but was deigned by somem Aussies to make it easier to change your map and other things by using a laptop instead of the hand held controller). You can change at what temperature the fans kick in with this which is usful aswell as a whole lot more stuff.

Dam you beat me to it, serves me right for taking 10mins to type two paragraphs  

[Sy.]

wow .. great info there guys .. thanks .

Definatly sounds the way forward ... can it be hooked up to a 6" screen and displayed more clearly (eyesight not as good as it was)

Next question .. where to get one that does not break the bank .

[allstaruk]

It can\'t be hooked up to a screen I\'m afraid, I might have a couple of second hand ones in the pipeline at a good price, will have to wait a little while to find out thought.

[Ada7]

So would something like this be the next step in getting some more use able power, and how much are they and how easy to set up?
At the moment the only engine mods i have are an Blitz Twin Filter induction kit and straight though Blitz Nur spec pipe.

To be honest Ada, from the little info I have found out in the last few weeks, if you are running a stock ECU with those mods your engine is probably not fuelling properly and running lean which in worst case could result in detonation, i.e cracked rotor tip, which would mean a rebuild. (what happened to me)
I would get it looked at by a specialist before you spend too much time with your right foot flat on the floor, you could save yourself some serious cash if you spot any possible problems now.

When they look inside and say \'yeah you\'ve lost a tip, thats a rebuild\' you will wish you got it looked at sooner! its not a nice moment!

p.s. anyone who knows more than me about rotaries (most people then) feel free to correct me if I am needlessly scaremongering here!

SORRY TO HIJACK THIS THREAD SY, DANDAN, any news on your engine yet? as to whats happened to it, how bad? i know a specialist guy in Bournemouth who rebuilt mine, not far from Southampton! is it under guarantee?
Cheers Bob
