High compression 1.3 running on 1.0L ecu

[Robert Whelan]

I'm running a 1.3 engine with the 1.0L pistons and ported head with std cams, have a 4 branch manifold and air filter aswell.

The question is will it run ok on a std 1.0L ecu I Know frank should be able to answer this no problem.

i ran a similar setup robert

Did you need to adjust the fuel pressure at all frank??

the a/f/r,s should be unchanged by those mods i guess mate, mine came alive when i fitted the SR t/b and QG injectors (and a ghetto rising rate reg that lowered the fuel pressure to about 1.5 bar at low throttle), and that recorded 109hp and 15.49 1/4 mile

Same question frank 1l ECU be better for 4 branch - ga15 TB - ga16 black injectors - ga16 ghetto induction system... Or should I grab a FPR too?

 

[frank]

I think you will overfuel at low throttle mate (and at full chat too)

Would it go lean at the same
Points on 1.3 ECU?

They have the same fuelmaps apparently. And the last 1.0 dyno printout i saw was mega rich at the topend

Wouldn't that be beneficial with the setup Id be using? With the extra air and whatnot

test it on a dyno and see

thats a serioius releif...... i thought i was going to have to go find a 1.3L ignition barrel. ive got the ecu from my old one, but if i can leave my standard 1L ecu in place then happy days
