The infinity 6 runs about $100 more than the 8h and I'm trying to figure out why. Would the 8h be a better option for the F20c or the 6?

 

No reason to run the 8, all it gives you is more cylinders to run which the S2000 doesn't have (obviously). I believe the 8h sacrifices some input/outputs to gain the extra 2 over the 6.

 

Unless you are running a relatively simple 8 cylinder engine, I would NEVER recommend an 8H over a 6. The 8H sacrifices two digital inputs (6 and 7) and two lowside outputs (6 and 7) for the two additional coils/injectors. The 8H can also only drive high impedance injectors, the 6 can drive low or high impedance drivers. Think of the 8H as a low cost 8 cylinder only box.

 

The 6 would be the preferred option for S2000 as to not sacrifice the outputs. We have these in stock with harnesses, and any sale includes access to our library of base calibrations make yours and your tuner's job a lot easier!

 

Thanks a bunch for the help guys. I was thinking that the 8h would be better because I will only be using high impedance injectors and if I ever needed to run 4 more injectors, I could with it. The 6 I don't think you can run more than 6 injectors. Hopefully I won't ever need more than 4 of the 2200 injectors but who knows. I'm going for around 1000whp on e85, so hopefully I have enough injector and fuel pumps (dual 340s).

SOS, I'm not finding anything on your site on the infinity for the S.

 

Id definitely go with SoS. I got my Infinity, harness and flex fuel kit from them. It runs like a dream, idles like stock and feels OEM on all other situations and its infinity, you can do damn near anything with this ecu.

They did the install and set up for me and it runs perfect!

 

You'll lose the coolant gauge on the dash if you opt for the 8H as it is driven by the lowside 6 output (only available on the 6). If you need secondary injection (8 injectors) and still want to have some available outputs, I would opt for the Infinity 8 (not the 8H), although this would require a different adapter harness.

To note, AEM has renamed its existing Infinity ECUs to accommodate the current and future expansion of its Infinity Programmable ECU model lines. "The success of the Infinity ECU program has created opportunities in multiple forms of Motorsports, which have subsequently allowed us to develop new Infinity models beyond our existing offerings," commented AEM President Greg Neuwirth. "This change serves to allow for both future Infinity model expansion and to eliminate confusion once the naming system is adopted by everyone."

Everyone goes with the 6 for this car. We've sold lots of those and not a single 8H for this car.

 

Infinity 6 as everyone has said. You are also going to run out of fuel, ask me how I know lol.

 

Thank you for your recommendation!
