Thread: New Beginnings - new life to an old 88

In both my '86 and '88 RRC i've had to pull the dash out to re-wire the ignition main feed. It wears through and creates an UN-FUSED short circuit with the body. Stupid design! My '86 nearly burnt down.

Well so far I have replaced the injectors with another set I had from a 94 Disco. the ones I pulled out were stuffed. She runs a little better now (has more pickup) but still hunting a bit. may need to re tune it gain with the better injectors in it..


Another question : I'm looking at the aftermarket ECU's to improve mileage. Been thinking the Wolf 3D plug in kit for the Rangie.. (its about $2000 for the system).


Does anyone else have any experience with this one or any advise on this model or any others on the market ??? not sure what would be the best...


Cheers,

Yay, oppurtunity for my first post. I don't own a Rangie at the moment, used to own an 83 two door and will get another one soon methinks.

Wolf 3Ds - for 2g you're obviously talking about a brand newy. I've had some experience with a version 2 and version 3, both on a naturally aspirated Suzuki Sierra with 1.6 EFI conversion. Both were what I'd call driveway tuneable, you could get a rough base map/idle from free revving before taking it out for short trips and reading plugs/listening for knock to adjust fuel and ignition timing. At this stage you should have it running well enough to get it to a tuner (in my case it was 900kms away.....turns out I wasn't far off, just had too little timing and too much fuel). Or you can grab a wide band O2 sensor, laptop and a mate and go tune it old skool on the road.

Either or, its very self explanatory to tune for someone with a rough idea of basic IC engine design. Obviously easier for a workshop with a dyno. 2g is a heap of coin, I'm assuming that's installed. That could buy a heap of cartons for you if you grabbed a 2nd hand computer and spent a weekend with a mate or two.

Conclusion is mileage may improve slightly with a tune but if your only mod is a small cam the expense may outweight the result. Good points of an aftermarket ecu are tuneability with future mods and better response if tuned well. It's probably the sort of thing you'd look at if you were going bonkers on mods or are keeping the car for >4years or so.

My 2c.

The 14cux ecu can be remapped relatively easily. I am about to do mine. Just need to enlist some help with the chip desoldering add mine isn't socketed.

none were originally fitted

How. Is it re-mapped and for what advantages? Would that include O2 sensors if not already fitted?

Remapping it by writing new chips. The fuelling tables can be viewed in rovergauge so you can see where it is currently running and I have a wideband o2 sensor for tuning. Tunerpro is free software which has all the file definitions for these chips so you can find the right values to change.

I believe you can run normal o2 sensors without much work and no need to touch the chip. But if you run o2 sensors then you can't use lean cruise.

Hey Dougal,

By lean cruise can I assume you mean closed loop? Just curious, whys that, does Tunerpro lock it out?

I think lean cruise is only possible open loop. In closed loop the o2 sensors keep pulling it back to stoichiometric of 14.7:1.

Tunerpro is only used to find and edit the maps.
