just an aside for gunnerchip owners/considerers....

[titcharoony]

Im extremely impressed with my gunnerchip for my williams...but I have noticed a drop in fuel economy. I used to get approximately 600miles off £60, or about 80 to 100miles off a tenner, if driven well. Ive driven with the gunner chip with minimal booting, and ive dropped to about 450miles. It might be just the way my car responded to the chip... but I might get gunner to do me a standard one, so I can swop back over to check and confirm whether I definately have lost some mileage from it. Performancewise though, Im chuffed to bits.

Like with any mod, it usually triggers a heavy right foot for a tank or two!!

As suggested, a heavy right foot is usually to blame! but the ECU needs time to adjust to the new parameters, its a learning computer after all, the chip simply gives it reference points and it calculates the rest via its sensors.

Secondly, all the gunner chips are mapped for v-power or high octane fuel, is this what you are using? if so what brand?

bloody hell im lucky to get 350 miles to a tank... no matter what ecu :wink:

The Williams ECU's learner ECU's?

[titcharoony]

learning computer? haha my williams ecu is the terminator t-800. haha, well yes I appreciate everyone thinks new mod= heavy right foot, and yes I have given it a bit of beans, but the last test was driven well with minimal booting. I run on v power only now. But from the convos with williams owners previously, it sounds like I got exceptional mileage from my car pre-chipping. 400-450 miles was average from £40.
Should I give it some time and see how its doing later?

[Lunner]

How the hell do you get that sorta mileage from £40....i'm lucky if i see 350

[Matty86]

I can get up to that on my valvers quite easily :?

[Crossers]

Frig me, 400 miles from £40.

Never heard of that before, i think your other chip must have been running rather lean!!

[titcharoony]

car always ran well...so dunno. my sisters 1 7 2 clio gets 450 from £37. so perhaps its down to keeping it std and keeping in good condition...my car is low mileage, oh, and getting 450 miles was possible, but it meant never really going above 3-3500 revs...at least 350miles from £40 regardless of booting :)

[Allan]

i have seen arj's williams get over 400 on a tank :D and thats cammed and mapped !


i got 470 out of mine last night before i had to fill up, but its been cold so i haven't been taking the car over 2500 rpm

[titcharoony]

i wonder why ive had a sudden drop in fuel mileage then? hmm hang on, i had a fuel leak, but then lunner changed and replaced the fuel lines...so it shud be back as normal..I might leave it a lil while, see what happens, then get a std chip for my williams, swop them over and see if theres any difference.

350 to a tank is good for me! tbh i think mines better on fuel since being gunnerchipped, keep the revs low and my foot off the floor and a tenner lasts a good while

[Crossers]

270-290 for me!

Suppose i should chill out with the left peg, but i'm always late for work!

God only knows what the fuel bill for the Tubbys gonna be!!
