[s-cars] 034 HO Coil w/ AAN ECU?

[Manuel Sanchez]

Brandon,

I've had the 034 HO coils on my RS2'd car for a couple of years now  
as well.

I had some initial "teething" problems that in the end turned out to  
be a bad ignition wire (it had a knick in it). Once that was chased  
down it has been trouble free (knocks on wood).

My OE setup failed about 15,000 miles ago, so I obviously can't  
compare the longevity question with regard to the OE vs 034 systems.

I must admit however that in the dark days on trying to chase down  
what the problem was with the new system I told myself that I should  
have just bought the more expensive OE Coils and OE POS's, after all,  
they lasted 100,000 miles.

Having said that. the 034 HO system is very simple to install, and  
the new ignition wire boots are of a different length that allows you  
to place the coil pack cover overtop them spark plug wells so you can  
keep the crud out.


I am curious though about these ECU chip failures you write about.  
Can you expand a bit more on what the theory or evidence has been?  
What aftermarket systems have "caused" or been thought to cause the  
Chip failures? Why does this person surmise that the coils have  
caused an ECU problem.

Regards,

Manny
