Thread: Fuel economy ugly, shock absorber tips

Hi daljames, yeah $100 is about right for Boge shocks but for Bilstiens you'll pay about $200 each. Good shocks though.

Also i am after new shock absorbers and am after ride comfort more than handling. Any tips? I've got a quote for OEM shocks $100 a corner. Seems reasonable..

Shocks sound reasonable and approprate to your needs, what do yuou rate as poor fuel economy? What is the L/100kms figure on trip computer?

Thanks so far people, i think ill stick with the originals Boges.

Fuel is around 22l/100km if im real careful. Live on the Northern Beaches of Sydney, so some hills. My old HSE averaged around 16.

My P38 had a Unichip which started fighting the Engine ECU so it was removed. Removing should be fairly simple process.

I'll check the wiring harness on mine and let you know... my notes have
green to white/red
grey to white/black
white to black

22L/100Km is way too high. I get approx 19-20 around town and I don't drive economically

Cleaning the MAF is easy - use isopropyl alcohol from JayCar and a can of compressed air. I haven't done a write-up yet, but there are some pics of disassembly and cleaning at MAF Clean

Changed the air filter... good. Change the pollen filters too. Your A/c will appreciate it.

Boges are far more comfortable than Bilsteins, but Bilsteins handle better... although I am currently testing some 12 way adjustable shocks that will sell at Hard Range for around $200-220 each when I work out the right combination for the lift kit. I'll be looking for a "volunteer" with a stock p38a to test the standard length shocks in the near future

Cheers, Paul.

Thanks heaps Paul. If you could let me know the wires that would be great., although there is a lot more than just three wires running from the chip to the ECU.

Ill be in touch next week or two (when i get the free cash..) for the brake modulator parts too.

My shocks are too far gone to wait for any longer so ill be getting the Boges next week. Much as i would've liked the idea of the adjustment!

Here you go... Unichip ECU removed and connector still in place showing wire bridges. One day I'll get around to removing the connector and wiring too.


cheers
Paul.

Thanks Paul, my wires are a different colour and in different positions so i just followed it all back to the ECM and all good. Ill take it for a drive over the weekend and see if the economy is any better!

I doubt it. It's more likely to be a sensor problem such as the MAF.
My unichip has been stable for 5 years now.
There is now only one Unichip tuner in Sydney. If you want to have it tuned please ask and I will dig out his details.
