Well, in doing some research on EMS for my car, I started to look into the MoTeC systems. I found that MoTeC Japan offers a plug and go system for the S2000. Looks interesting. Based on my understanding of the rules (correct me if I am wrong) that a stand alone is not allowed, but a piggy-back system is. it can control the injectors and timing. Any thoughts?

 

MoTeC.....for the Hardcore tuning in us all...

 

What class' rules are you attempting to meet?

 

At this point, none. The car is for fun. But I would perfer to build the car that falls within specs generally. It has to do with resale if I ever need to . A car that meets spec is worth more then one that needs a ton of cash dropped into it. By the time I am ready to go W2W the spec's will have changed I am sure.

I think that NASA Honda Challenge and SCCA T2 both allow piggy-back fuel managment systems.

 

if they allow the motec they'll allow the ems. why not run something that's not a piggy back? There's another ecu option coming soon, but I can't say who.

 

I am open to all options. So far Motec seams to be a leader in the market for EMS and EMS support. They just seam to lack S2000 details that are publicly available. the bigest deal is a tuner that can work on the system. Here in Texas, AEM EMS tuners are few (that I would let work on my car).

The M4 will run the F20C without anything else. This just looked creative. In my exchange of e-mails with the JDM Motec guy, there is 20 cars they have prep'ed using this method. I would guess that their rules allow a piggy-back.

I reread the SCCA GSR, I could not find what I read before. Everything I read now (2007 GSR) is that the OEM EUC housing must be maintained and all changes to the ECU (and they are not limited) much be made in the same housing. So that means to me that all Mod'ed OEM ECUs will pass (J/s, Mugen and the like).

It must have been the NASA rules that I saw this in. Off to reread them again.

 

that rule is for the SCCA IT class (ie itr) but piggy backs aren't allowed tho. So the motec system isn't legal there either. exactly, you would need to run a mugen or j's or just stock in those series.

 

open your stock computer gut the insides n put the motec inside
then it meets your specs

 

For Touring2 (now T3) you can't do a piggy back or the Improved Touring Motec-in-a-box method because only the programing can be altered and you have to maintain ODB2 and CEL light functionality.

Also for Touring you have keep the full interior and stock suspension (except dampers) which is usually that last thing that anyone thinking of building a race car thinks of.

 

Take a look at the HKS FCon-VPro. It piggybacks to the stock ecu, but takes over timing and fuel injector control. The fuel and timing maps are 32X32. I'll be switching to it shortly.
