Finally it's official, i'm adding another 4 cyclinders

[chimpboy]

Unless you like piss fart arsing around with after market computers I would suggest keeping the standard 14CUX. It will be far less hassle and much cheaper.

I second this. At least for the time being, it will keep things much simpler and quicker for you. Plug it in, hook up three or four wires, and you're done.

true, but i have gone to thhis extent on stroking the motor, so i want to extract everything i can out of it. surely they can't be that bad

4.4 isnt much of a stroke dude, and yes they can be a total pain. Its the small things like cold start, and idle after deceleration that can cuase problems. The factory ecu is the best at controlling all the small things.

[def90]

yeah i know 4.4 isn't much (couldn't afford forged pistions for the 5L - but kicking myself now)

aren't most computers tuned for cold start, hot start, etc haven't looked right into this yet...

[nottie]

after market computer would probly need to be tuned in on a dyno.

more than just the dyno. You could get good power figures from a dyno, but ironing out the onroad habits can take months.

[def90]

we were just going to temporary tune it on a weekend driving around with the laptop, no charge for this. cheaper then big bucks on the dyno, at this stage.

[Hally]

X2 on the aftermarket ecu I run a Haltech EX6 and the mechanic spent weeks of trying to get the cold start right and its still not some days it's a pig to start and other days it kicks first go and also what Grimace said poor idle after deceleration mine will be going back in for another dyno tune when I get back hopefully you wont have as much trouble as mine did Fingers crossed I'll be back in brizzy in two weeks sam so if you need part numbers let me know

A few of the D90 rovers are running 4.6s with the 4.2 RR computer, even better with a tuned chipset.

[def90]

what would the differences between 3.9 computer and manifold and say the 4.6 computer and thor manifold? is it easy to remap the 3.9 & or run bigger injectors if needed? as i don't know if the stock 3.9 that would run to lean? - or run a piggy back system?

14CUX (3.9 ecu), with a thor manifold on your 4.4 will give good figures down low, and be great for not only offroad but onroad it will drive with ease, it's all the benefit of having 50% more power downlow where your engine spends most of its time.

The thor manifold generally reduces power at the top end, and will not flow as much HP as a standard 3.9 plenum.

I personally think the 14CUX will be fine, and to get a bit more out of it later down the track you could fit and tune a piggy back ecu.

There is a few modifications needed to run the thor manifold and it will be costly. I would budget an extra $1000 over the cost of a standard 3.9plenum installation. You will need a fuel rail out of a 92 rangie or later aswell.

I had a list of all the mods needed that I got from a fello rangie owner who has done the swap on his 3.9, if you do get serious on the thor I can confirm everything needed and forward the information to you.

Might also be able to do two at once, as I am still wanting to fit the thor to my 3.9 POS.

cheers grimace, mate when you have time if you could send that through that would be great.

hows the 90 coming along,im moving to the goldy in the new year so well have to go for a wheel

He sold it! Abandoned

Look forward to your arrival, We need more LRs up here to show all the pootrols how its done

Couldnt sell that!!!!!!!! Jeff

ha you can talk grimace!! by the way when is yours coming ou to play? another year or 2?

the wombats in at the moment getting the megasquirt and injection done, hopefully back for a shakedown next weekend!!!!!

great stuff on you moving to the goldie defmac, yeah it'll be sweet to wheel with more fenders/rovers!!!!

[GRIMACE]

ha you can talk grimace!! by the way when is yours coming ou to play? another year or 2?

shut up!

[def90]

finally got the wombat back a wek or two ago, and really happy with the injection over the carbys!!

heaps more low down torque, smoother idle, easier start. runs pretty well for a little 4.3.

haven't had (yet) any issues with cold/hot start, or idle issues. hasn't been dyno'd yet - next year sometime.

my mechanic had heaps of issues getting the tune right, but after trying different computers, etc, etc, etc found that the dizzy was playing games and fitted a optic? dizzy, and bingo problem solved.

ended up using the 3.9 plenum and obviously megasquirt system mounted behind passenger seat.

now questions, from moving from a manual isuzu and barely using the brakes at all to a v8 auto i have found how crap the fender brakes are!! especially towing!! what are the possible options for brake upgrades? haven't checked type of pads, etc yet.

need to lift the rear a little as now the front sits higher. with the isuzu the bump stop heights were
(passenger front) 85mm (driver front) 90mm (rear pass) 110mm (rear driver) 110mm
now
110mm, 110mm, 115mm, 115mm

haven't really wheeled her yet (just camp mtn rd - cruiser park, still felt fairly stable - no lifting front wheels) to see how the weight difference off the nose and auto work, next wek or two will get out for a proper play at ormeau to suss her out, then in a few weeks rip out the xfer for some 49% gears

will get some pics up shortly.

[defmec]

good to hear .did u do any mods to the trans or is it stock .my mates got a zf lying around ill be looking at fitting to my county . have u got discs in the rear or drum as my county with drums doesnt pull up as good as my defender did

[def90]

hey defmac the ZF is stock - we'll see how long it stands up, although its not a daily driver.

mate had drums in the rear originally but i put a disco diff with discs on, i think the later defender (TD5's?) had bigger brakes then the earlier ones?

[def90]

coupla pics



wiring still needs abit of a tidy up




just had a tub, shortly after piss'd down while out with no roof

[ISUZUROVER]

Looks GREAT!

[def90]

position of shifter. just need to make a little cubby box around it to tidy up abit, then some more gauges - auto temp, etc

[Micka]

Looks GREAT!

Yeah it does look good, Ben...but its just a poncey Macca's carpark wheeler. Actually...its more like a ricer on 33" tyres.

I was embarassed to have it parked in my driveway yesterday, even though it was for about 4 minutes.

And it absolutely bucketed down second after he left for the 2 minute drive to his place...but then his wife had to open the gates, and then he had to reverse 25 metres up his driveway to 'Church' to put the g-h-e-y little thing away.

He'd be lucky if it didn't shrink in the rain.

Well if you had your fuel tank fixed we could of gone to maccas together today and played in the puddles i would've even let you still borrow my 35's so you can get over those speed bumps

i'm coming around to get those 245's soon.

Not to self: don't forget to install pretty strobe lights and big subwoofa.

ahahaha and how many actually work

leather seats??? whos the ricer boy now have you had them colour coded yet??

you can have ya fancy longfields, i'm happy with my mate jacmac (so far anyways)


cheers ben will look into it.

The front two work and that's all I care about

I would have gone with JacMac...but RoverTracks was cheaper
