Che'_Moderator Posted May 2, 2007 Report Share Posted May 2, 2007 AF looks pretty fat but as far as that it provides thats very good. Whats up with that tune though? Was that a dyno pull? Looks way off if that was an actual street log. Link to comment Share on other sites More sharing options...
SkyWriter Posted May 2, 2007 Author Report Share Posted May 2, 2007 with cycles of 30-50mph over 10-15sec and never going to zero it looks like a pull. he mentions 'pit row' in a later post... i don't see anyone doing this on the road (at least not while i'm around ).wonder why the AF peaks to 73.5 when he lets off the gas?

For a dyno pull looks good. If it was a road pull somethings set up way wrong. Link to comment Share on other sites More sharing options...

Che'_Moderator Posted May 3, 2007 Report Share Posted May 3, 2007 yes, and i used the internet in the 70's but it was called DARPANET.Actually in the 70s they were ARPA. Then they were DARPA, and back to ARPA in the 80s. Late 90s with the FSO and DSO branches they went back to DARPA. Several friends still work there and I give them shit about it.

Furthermore, if this were a dyno pull why does it look good? Link to comment Share on other sites More sharing options...

Either: The intercooler must be like 65% efficient It has a total suck intake set upIt was a dyno pull Link to comment Share on other sites More sharing options...

I know in my 850 I've seen this happen on my wideband sometimes when I coast to a stop, it'l show atmosphere AFR's, sometimes for many seconds. Almost like a half-assed jake brake. The pattern is almost identical to what you see there when you graph it. Link to comment Share on other sites More sharing options...

The pattern is almost identical to what you see there when you graph it.Only track cars are going to cut ignition. A lot of them link it into their ALS. As for fuel its not being cut really. You just have a weird condition created by the TP being 0%, the engines generating high vac, and the load sensor being at 0 all a split second after being the way. Its just latency. oh what do i know; i only designed minicomputers in the 70's.Then you think you would have gotten it right ;) Link to comment Share on other sites More sharing options...

Che'_Moderator Posted May 3, 2007 Report Share Posted May 3, 2007 ok you can have a cookie. Just busting your chops. So ipd sold any of these yet? What all can it do? I mean it data logs so I assume you can change the variable multipliers and stuff? Link to comment Share on other sites More sharing options...
