Freerider well done on the variloks.If they work half as well as the "varilok"between the front and rear on my Grand then you will be happy as.
I have been reading up on remapping and chipping in relation to the WG 2.7 diesel.I would love to say that i have found gold, but sadly ,no. Any way it is an interesting subject,even the pros and cons re remapping verses chipping.I have been trying a few different circuits to wind the boost up a little.So far i have had limited success.I can lift the boost but some times it will throw a code.Reason why i started down this path was when towing the 2Tonne plus caravan,at full noise ,up steep hills i could see some black smoke in the side mirror.Back off a touch and the smoke goes away.From previous turbo diesel experience, this would mean too much fuel/not enough air.OK, so how do you wind on a bit more air on a 2.7 crd?
What i have been trying is put a "Circuit" between the boost pressure sensor and the ECM, on the signal wire.
What i want to try is when i am towing and at full throttle and see smoke in the mirror(contrasted against the white caravan also in the rear view), may be i can throw a switch for 1 or 2 psi more boost and see if the smoke disappears.
By the way i have done a leak down test and results were 5ml for each injector over a 30 second test time.I think i read in the workshop manual that 20ml per injector over 60 second time was OK.
Has any one here done anything re remapping,chipping,roll your own circuits??
When i got any good results that are reliable and dont throw codes i will post it up.
I hope to be able to be able to switch on some more boost and also more fuel when needed, and switch back to standard again , at will.
Anyone got any results from their own tuning/remapping/chipping or just opinions please share.
