Running issue need some help

[kaneda]

Some background on the tune............. Its supplied by GIAC for a 1.8t with Ko4-01 , 3" Maf , 380cc injectors ,TIP and upgraded intercooler. The car had a GIAC socket fitted when i purchased it and when i was looking at removing it I found out that they would remove it and "flash" a tune on the car for a very small fee. Now i was sold on custom code as the customer service was awesome but in my current position couldn't afford the luxury
So now ive got an issue that may well be software related but have no idea as Giac suck balls at customer service.

Good lesson in this I guess ........... had i waited until i could afford the software i wanted rather than what i could afford I dont think id have the issue at this point.

Happens to the best of us, its called a learning curve...

Ok, so the parts form elements of a 'Stage' of tune, sounds good. Your issues could relate to a faulty part, unfortunately without Vag-com, it can be a guessing game working out what is wrong...

I'm sure there are plenty of these tuned setups on Tex, have you looked around there?

A cheap ebay cable gets you access to vag-com and adaptation programming (very limited). Given your issues, I'd invest in one of these, atleast so you can determine your issues further or maybe get a work-around.

Steve, you need the element from a MK4. Get the part number off the original MAF housing. They have 4 pins in the plug. Have a word with Jmac or Golfloon.

Remind me again what the part number is on your ECU? We have swapped an AQ for a CH recently with no ill effects. Might be an easy way around your software......

Ben, the ECU in the MK4 is ME3.8 and not half as clever as the ME7 in the newer MK4s outside Australia and of course your Polo. There is limited logging capability with VAG-COM and for the most part you really need to log it with an external device and wideband lambda probe.

Not sure what you mean by AQ and CH but my ecu number is 06A 906 018 BB..... the good thing is tho that my ecu has had the socket removed and the Giac file has just been flashed so should be easy to change once funds permit.

I was wanting to know what the letters at the end of the part number were. I can get a file written for your ECU with the KO4 if/whenever you need it. To get it spot on though will need the LM1 and data logging doing.
Might be worth you hunting down another ECU if you can get one cheap enough, recoding the immob is easy enough.
Having that socket taken out is a bonus.

I had a chance to have a bit of a play with the car today.............. I changed the maf housing back to the original size on the advice of the supplier of the tune to see if it fixed the issue and noticed that it now runs very rich. Now the manufacturer of the software tells me they have no K04 file for an cable throttle AGU except for their standard upgrade tune and this got me thinking that maybe this is all i have and the larger maf housing was canceling out the larger injectors i was using ???? Anyone in the know think im onto something ? or am i just showing how little i know about VAG ecu's ....

Like the others said, check both ignition and fuel.

Hang in there as frustrating as it may be.
