For a while I've enjoyed driving Mk2 Golfs, particularly the GTI's. My first GTI was a bored out 89' 1900cc 8v running the original Bosch Digifant 2 system with a modified Air flow meter and possibly chipped ECU from a company called TSR.
At the time I managed a race car team who had an old DTA S60 pro ECU kicking around and worked out a deal to purchase it, long story short that this never came to succession. And unfortunately the golf and ECU had to go .
So after lasting just over a year my urge to own a questionably unreliable car has struck once again. This time in the form of a later MK2, a 1992 4 door car, I paid relatively peanuts for it and drove it 140 miles home on roughly 3-4 cylinders!
This car had been converted from its original 8v PB engine to a 16v KR engine. These 16V engines were controlled by a mixture of mechanical and electrical components, with the fuelling governed by Bosch CIS (Continious Injection System ) also known as K-jet, whilst the spark is governed separately using a control box and a hall effect sensor in the dizzy.
I did try and spend some time to get it to run properly, but discovered that basically the entire fuelling system needs overhauling, from pumps, to filters, metering head, cold start valve and injectors and new HP lines. The cost of this would be easily over £500 to do this, plus tuning. So that's why urge for modern day EFI is wanted here.
Happily, I work as a Calibration Engineer, tuning various standalone ECU's on a rolling road (DTA, OMEX, Emerald, Motec, Life Racing, MS, MBE, Haltech, Link etc etc). So the tuning side shouldn't be an issue for me (oh how I could regret saying that!).
What made me interested in Speeduino is the open source community for this, how is constantly being developed to be better and better. Many standalones I get frustrated at that certain simple tasks cannot be done because the manufacturer will not let you.
Anyways, back to the car, the engine needs a rebuild, to convert it to EFI (trigger disc, TPS, injectors and fuel rail) would again cost around £250 to do so, plus the engine itself needs a full overhaul, as its leaking oil and its core plugs are cream crackered. The MK3 2.0 16V ABF engine was the first GTI 16v engine to run what can be considered a modern day EFI system, using a Bosch Motronic ECU. These engines have been used heavily inside the Mega squirt world, so should be a good engine to use.
My Goal: To make a reliable, relatively presentable MK2 run on a Speeduino UA4C, that I can make as OEM as possible to drive, with good fuel economy but with decent power.
More on the details on the second post!
