rev limit cut?

[mugen_ctr]

Quick question guys, Do the OBD2a and b (1996 - 2000) ecu equipped vehicles use fuel cut, or ignition cut or both?

[Chernoby1]

I do not have the answer BUT id assume its both. More interested to find out why your asking :D

defs fuel cut.

fuel cut

Without ignition cut? Wouldnt there be issues with a *possible* small amount of fuel making its way in and it igniting a very lean mixture?

[mugen_ctr]

ahh cheers guys just wondering lol...

as far as im aware fuel cut is more safer as ur not throwing away unburnt mixture which can ignite in the manifold/exhaust which = cool flames shooting out and fuel cut runs smoother

[dougie_504]

That's exactly right.

[Chernoby1]

Not to mention the emissions mega fail of spsrk cut...

But I still dont see why they wouldnt cut both. I can only see upsides to cutting both but there must be a reason they dont! Anyone have qny insight?

I know what your saying, but they only cut fuel, they must have a good reason for it for production street cars. Its not every day an ordinary car and road user hits the rev limit.

Hondata add-ins give you the option to cut fuel and ignition
