I've got a chance to buy an SDS fuel computer for $350. I'll be using this to replace the carb setup on my racecar. Currently its a stock port 13B and I'll be using a stock S4 intake. Does anyone have a map I can start with? Ignition will stay the same(direct fire setup).

I have a S4 N/A Map for a E6K if you want it.

Not the same. Thanks anyway.

Check on SDS tech forums There are a few rotary people on thier that may be able to help.

Thanks TheCamel. I've been to there site numerous times over the past few years.



I've found a fuel map on somebodies website. His intake is the same as mine but he doesn't have a ported engine. It will be close enough to start the engine with and run it some but I'll still have to schedule some dyno time but thats ok. My engine builder and I are wanting to get some dyno numbers so he can sell more 6-port engines and and tell the customers what kind of HP/torque to expect. I'm kinda the guinea pig, but I'm fine with that. The N/A crowd and especially the 6-port people are always bickering about the capabilities of a ported 6-port and this might help some of the bickering and misinformation on the internet. At the minimum, I'll know what I've got:)

Well I know the system you are talking about, I have one awaiting my turbo conversion, the problem we found with SDS is that over 400hp on a TII engine the SDS could not keep the timing accurate, I have a Electromotive HPV-1 that will handle the timing now. The SDS is a good tool and cheap. The system I bought was used on a fairly moddified TII at close to 500 rwhp so I know it will work for me. https://www.nopistons.com/forums/pub...#>/biggrin.png
