Mexican fuel injection

[parris001]

I thought I had heard that the Mexican Beetles used a fuel injection that was never offered on US models.

I like different kind of stuff, and would like to try the Mexican fuel injection on a carb engine.

Ever been done before? Too stupid of an idea to try? Did the Mexican Beetle have a better electronic ignition than the crappy points that we use? (Don't try to swap me over to the Pertronix. I had that system and threw it in the trash)

I beleive 75 and later had it stock in the states and it is pretty reliable.
There is also a pretty good aftermarket for parts,also hot vws has a project milage feature going about an F.I. type 1
go for it.

Has anyone ever installed a Mexibeetle EFI in a 70s bug? I'd like to get the 28 - 36 mpg that Mexibeetle owners report.

Antonio,

Do you sell the wiring harness with connecctors for the MX MAP distributor, and sensors on the throttle body?

Andrew,
The sensors (TPS and Air intake temp sensor) are included on the used throttle body from my basic EFI kit. I have for sale the genuine and new engine bay area wirinng harness, to conecct distributor Hall sensor, TPS, , injectors, engine temp sensor, ralenty valve...

I don't understand. I've driven a Mexican beetle. It didn't seem to have much more power or speed than my 61 beetle with a 1600DP in it. My car got an average of 33 mpg on my trip from Arizona to Ohio. Why would a Mexican beetle with electronic everything get worse mileage than my 61 because of gearing??

I managed 49.9MPG (UK) on my Mexican 1200 bug (supplied to Europe by VW until 1985). Same trans as current models, well gearing anyway. 4.37 R&P needs dropping to a 4.12, and 4th to a .89 to make full use of the FI motor. I will be doing this to my '98 when I get it back together.

The Digifant system on the Mexican bug is pretty much the same as in a current Golf etc. Together with hydraulic lifters it is a huge step forward.

I have a beautiful 71 bug with a 34 pict 3 that runs well I am super happy.

I would LOVE to buy a spanking new ( or close to it) used Fi mexi beetle.

I have seen a couple on ebay and its been tempting BUT.

As far as I can tell from phone calls and visits to the VW dealers in NY state NO ONE (dealerships) SUPPORTS THEM OR HAS ANY CLUE HOW TO BEGIN TO SUPPORT ONE IN THIS COUNTRY. I explained what I wanted to do to the service manager and he thought I meant a water cooled bug. when I explained it was a mexi beetle etc etc air cooled he stared at me blankly and had no idea what to say. The guy in Poughkeepsie told me that VW does not offer universal service info to all its techs, they wouldnt have the tools or know where to begin. They went to far as to explain they couldnt even offer me parts if I had the numbers.

This is the reason the Mexi's scare me, If anyone has any input as to wether or not VW stealerships in this country can or will service one let me know.

The air-cooled “Sedan” model produced by Volkswagen Mexico in the 1993-2003 years used the classic 1600 engine with some updated components. It is known as the “ACD” code engine. Differences from the engines in older models include:
1. Hydraulic valve lifters similar to the type 4 and waterboxer lifters are used, so valves stay in adjustment and should not be adjusted between rebuilds.
2. Revised cylinder heads that take a ¾” reach sparkplug.
3. A full-flow filter pump is used with larger (30mm) gears for higher oil flow. This provides better filtering to avoid fouling the hydraulic lifters. Because of the higher oil flow, pressure is better maintained in hot climates. Factory spec oil is 15w40 for the Mexican climate range; but in a wider temperature climate a 5w40 or 0w40 synthetic is more appropriate. The 70s dual relief oil pressure control is used. The spin-on filter is the same as used by most water-cooled VW 4-cyl engines, and the anti-drain back of the Vanagon waterboxer filter is helpful.
4. An electronic ignition distributor is used with no advance mechanism. Ignition advance is controlled by the electronic Engine Control Unit.
5. A combined ignition coil/spark control unit is used.
6. No thermostat or air shutters are used in the cooling system, as the ECU controls mixture during warmup to prevent fuel washing the cylinder walls. However, the fan shroud design has not changed, and the shutters and thermostat can be fitted (by drilling and tapping the case for the thermostat mounting stud) to provide better airflow for cold defrost of the windshield.
7. Fuel and ignition are controlled by a Digifant 1.82 ECU system. This system is unique to the air-cooled engine, although similar in concept and procedures to many VW cars. The control unit includes non-volatile memory for storing adaptation values matching the ECU to the car sensors, and for storing fault codes for diagnostics. The Digifant ECU communicates for adjustments and diagnostics. It is intended to use the VAG1552 or VAS5052 diagnostics tool used by VWoA dealerships. However, it does not use the now-standard 16 pin DLC connector as do US models, so it requires an adapter cable.
