Alternate ECU's- my thoughts, your opinions? Options

[ottox914]

I'll be running the yellow car in DSP next season, and we (this forum) have got the suspension in line with "how much bar is to much bar". On to the engine. DSP needs a stock long block, but intake and exhaust systems are free. I've got a Kerry Hunter header and supertrapp exhaust on now. So- on to the intake system.

Was planning to use the existing intake system, as it is more budgetary, and more torque oriented. Maybe over the winter research and build new runners and central plenum. But how to control it all?

I've been waiting as patiently as possible for the KitCarlson system, but have had other thoughts of late. With the KC system, you need to set timing values, fuel values, develop a VE table, and so on. And at this point, its all closed loop. Sounds like alot of work.

Plan "B". Go to "aircooled.net" http://www.aircooled.net/new-bin/viewprodu...0007&cartid=and check out the safeguard system, as an ignition upgrade. Hook this up, and the timing is self adjusting for fuel quality, temp of intake air, height above/below sea level, etc. Then add a megasquirt, SDS, Haltech or other fuel only controller. Beg, borrow, steal a wideband O2 and let the timing self adjust, just keep dumping fuel till you get good O2 readings across the RPM range, and tuning is done.

Can it be that simple? Pros and Cons of each plan? Thoughts? Other ideas?

Thanks!

The SDS and Haltech will come "blank", and you'll need to start completely from scratch on developing fuel maps

That's not true about the SDS system at all !!!

Have you ever had/programmed one????? <_<

Mine came programmed from SDS (they asked many questions about my app.) and it was right in the ballpark. Do to all the variables in the engine combo I doubt if the KC system will be a whole lot closer...maybe just a bit.
For the MAP I can give you mine. Programming is not too difficult for the non-techie anyways.

As far as the install goes, it is a lot of work for the crank fire, but I'm glad I got it. Without the crankfire you could probably have the SDS up and running in a couple of weekends.

The KC system will be easier to install on the T4 when it comes out

Yep, it won't add much power over the stock system on a stock engine.
