Thread: Power chip for a disco2 v8!!

Bruce Davis Performance Landys at Annangrove do one.

Bruce wants to chip my P38A.

What sort of performance gains will this chip offer?

I can understand how a chip would work with a TD motor, but on a naturally aspirated motor, it probably can lean out the mixtures or enrichen the mix, but will this cause problems for the motor long term?

Or will it be just more fuel = more power = more fun but at even worse fuel economy.

Thanks Ron i thought bruce would have to do one.

CHEERS TIM.

Isn't your motor the early type of injection, D2 is different to 1995 4.6 P38A

I had my 2003 4.0 chipped yesterday with a Haltech unit from Graeme Cooper in St.Peters. I obviously have not had time to detrmine my fuel consumption but when dynoed I recieved a 30Kw and about 30-40Nm power increases. This sort of increase is certainly noticable on the road and the low down torque (idle-1700rpm) is greatly increased.

I had my 2003 4.0 chipped yesterday with a Haltech unit from Graeme Cooper in St.Peters.

When you say chipped, what exactly is that? An ECU replacement chip, a reflash or a whole new engine management system?

Just wondering cos I thought Haltech only made complete programmable fuel/ignition management systems, not just a chip.

Is yours the high compression 4.0?

Those are impressive gains. Wonder what fuel consumption improvements you'd have.

Bruce Davis was talking 10 per cent gains in perf/econ for around $500 for a new ECU chip. What did your set-up cost, if I may ask?

Hi 4x4V8,
Sorry, I wasn't too informative in my comments. The Haltech unit is a complete Management system ($1200 Incl. install, configs and Dyno)that plugs into the existing ECU, which also means that when I sell the vehicle I can just unplug the unit and add re-install it into my next vehicle. I have a High compresssion 4.0 and as I commented before the low down torque is a complete transformation. We did a Dyno last week on the stock engine which produced 68Kw's at the rear wheels which I am told by Graeme Cooper was a little on the low side. I checked engine compression and all clearances which were all well within recommended specifications (engine has done 58000Klm's).
I have been told that the ECU upgrade that is supplied by Bruce Davis is just re-mapped chip and is not configured to your indiviual engine tolerances so I think the extra money is worth it.
I will let you know the fuel consumption figure at a later date.

Cheers
Glenn

P.S. - This is my first ever LR which I have owned for just over 2 months. It is a fantastic vehicle but I have been getting around 22-25Lt/100 in Sydney suburban driving which has blown me away as I expected better. I have asked a few LR mechanics and they all say that this is normal. Any opinions on this subject would be great feedback.

Haltech do make plug in interceptors as well as full stand alone ecu's. IMHO you can go past a stand alone system, but a inceptor has the benefits of being cheaper to fit and easier to transfer to a new vehicle.
