fuel cut off?

[bobbyspider]

Any way to change the fuel cutoff in the ecu on a b3 to maybe like 6700?

I believe rocketman discovered the b3 ecu has no removable EPROM. Therefore it isn't remappable like the b6t ecu.

i havn't broken one open to see where the filter is for the fuel cut off... i suspect that since there is no e-prom, it's a hard wired filter and relay.

Safc neo?

[Rocketman]

SACF isn't going to help, more than likely WOT is pre-mapped and it won't pay attention to any of the sensor inputs anyway. A SAFC will only modify sensor inputs to the ECU.

You may be able to change one of the cystal resonators in there that sets the clock speed, I think one with a lower MHz may bump the rev limiter up.

I still have that B3 ECU around here somewhere, I'll try to find it

Can you guys run a B6 ECU? Those may be able to be modified.

[bobbyspider]

Check it out for us please matt. For us guys who are going b3t it may come in in handy

[FestYboy]

we can run a B6 ECU with the B3, but the fuel and timing maps will out of wack. now if the B6 has an EPROM, that no longer becomes an issue.

[Rocketman]

See if the two-plug B6 ecu has a ROM in it. I may be able to do some things with it for ya'll.
