Rich ? is that correct.
when they say "Classic Fuel Injection " they are actually refering to their own hardware not the electronics. A bit confusing I know but for a time after Accuform purchased the deal from Dynaformance they called the system "Classic Fuel Injection " and only recently called it Eight Stack.
There was a lot of negativity about the previous owners, Dynatek and, rightly so, they are trying to distance themselves from the problems therein.

We are the UK dealers/ installers for EightStack and have dealt over the recent past with both the previous owners and now Accuform. There is no comparison, Accuform is a top notch company and the product is now great.

We have probably installed more of these kits than anybody else and have more on order and in the pipeline. We use Accel DFI for all our kits and IT WORKS so if anybody needs any info on the Eight Stack kits, please ask.

Which Accel system? My Roush setup used the Gen 7 version and from experience I can tell you that unless some very careful attention has been paid to the altitude compensation table it will not work well at 5000' if the calibration was done at sea level. Furthermore, the lack of backpressure invalidates the table if the calibration was done on a classic exhaust system (e.g., Mustang) vs. the side pipes of the Cobra [as Roush can now confirm].

I became an Accel DFI guru before I was done. [Not that I really wanted to, but it is interesting how it works, and when the table is correctly populated it will go from sea level to 10000'+ with no difference in performance.]

Just a heads up...

I would expect the self learning systems would be easier to handle in this area.

No matter what, the system is gorgeous, especially the one on the FE.

Tony,
yes, we use the Gen 7, the Thruster ECM is OK but you really need the capability of the GEN 7 in case you come accross any tuning "issues "
Agreed, the Roush calibrations do need work but at least with the GEN 7 it is something you can do.
It may suprise you but actually, in the UK, driving at 10000ft or 5000ft for that matter is not an issue as there isn't anything at 10000 ft ! ( or 5000 )
However the Accel ECM is the only plug and play that does have an altitude compensation capability built in so when we go touring in the Alps we are all set up ( maybe next year !)
I don't think the self learning stuff is really suited to an IR system, too many variables, better off with something you can control.
