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!

I've got an old SDS EM-3D(? - fuel only, 4 cyl) that I could be talked out of. I've been saving it for some future project car that I don't have yet;) I pulled it out of my old Jeep about a year ago before it went to 4wd heaven... It ran my 911 during its breakin process (had to add 2 more injector drivers, but thats reversible), but now Im using a Haltech E11. No fault of the SDS, but I wanted datalogging. The SDS is an easy system to get running. Im using the LM1 WBO2 w/ the haltech and that thing is worth its weight in gold. Wish I had one years ago when I installed the SDS in the Jeep. Friends don't let friends tune w/ a narrow band...
