Tune Up Planned for 420a Turbo Microsoft Car , to fix Over rich fuel mixture

Microsoft Turbo Talon Needs a Tune up

Well my car has been acting up lately. It does not seem like its truely a new problem. The engine has had an issue of slightly running rich for as long as I can remember. It fouls the plugs out in a hurry now. I think there is somthing wronge. Maybe a 02 sensor, maybe somthing else? I am going to take it to a shop to investigate what is the culprit as its been too cold and wet to try and figure things out myself. Here is the Instructions for the Hahn Install. These are the old version on the instructions. As you can see it offers alot of adjustability. The car has been acting like its ignition is misfiring or somthing and when idling it smells strongly from unburnt fuel in the exhuast. It can cruise at 2500 rpm but then after maybe a minute of steady cruising it starts to bog down like its being flooded. The symptoms get worse and worse then when I park the car and come back a hour later it runs much better. Its almost like spraying carb cleaner in a running engine. I tried changing the plugs, the plugs were very black and coroded looking. Soon as i installed the new plugs and spark plug wires, the car ran super great!! It only took a couple day though before its already fouled these plugs out agian.


Candy Red Intake Perfectly Clean, inside and out. I may port the flasking ( the rough bumps and mold marks from manufacturing cast Aluminum) out , but only a mild port, no Diameter exspansion of intake runner. On the right is the top intake plenum and left is the lower intake runners with injector holes.

I am going to take it to a Shop to be fixed and ,while they are at it, install a Apex- Safc II Fuel computer, maybe a o2 sensor ( I have a spare), and whatever part needs to be replaced to fix the check engine light so I pass emisions testing in the next 4-5 months when its time to register agian. Oh an yes the chek engine light is on too.

I have a Apexi Safc II to be installed I have been waiting on the injectors. Safc allows you to adjust the injector pulse to accomodate the air flow "curve" from turbo charging.



The second-generation S-AFC is a fuel computer that adjusts fuel/air ratio by modifying the air-flow meter/MAP sensor signal. The NEW S-AFC II is loaded with new features. Smaller, lighter, single button toggle control of all features. Knock sensor function alerts of knock signal. - silver case displayed. black version is no longer availableIt features a user-definable, eight-point, adjustable fuel curve that can be set in 500 RPM increments. The range of fuel adjustment is +/- 50% at each of the user-defined setting points. On hot-wire vehicles, the Deceleration Air Flow Correction function is capable of curing the erratic idle and stall problems associated with open-atmosphere blow-off valves on hot-wire air-flow meter systems. The S-AFC is capable of monitoring and replaying the following data channels in Numerical, Analog Meter and Graph displays: Intake Manifold Vacuum/Boost Pressure, Air Flow Capacity, Intake Manifold Pressure, Karmann Frequency, Engine RPM, Throttle Position, and Air Flow Correction %.

I may have In-Tune of Cleveland 423-336-5850 do the Install of the Apex unit, injectors, Clean new intake manifold and Dyno tune. I spoke to Scott and ee says he could do it all together, install the manifold + injectors together then install the Apex computer and use the Apex computer to Tune the Microsoft Talon on a Mustang Dyno for $350
