Re: Small lean-outs on Tip-In

I don't think you're lambda will react fast enough, and with large transients from low RPM you will probably get a lean spike due to a momentary loss in atomization. Suddenly you're putting a lot of extra fuel in but the airspeed is quite low, compared to say 4000rpm and 0.1bar of boost.

You should ...

Re: Cal Switch settings

You are correct in your assesment of what is required.

CAL01 = 0.015V - Thresh01 = 0.3v
CAL02 = 0.61V - Thresh02 = 0.9v
CAL03 = 1.23V - Thresh03 = 1.5v
CAL04 = 1.83V - Thresh04 = 2.1v
CAL05 = 2.44V - Thresh05 = 2.8v
CAL06 = 3.08V - Thresh06 = 3.3v
CAL07 = 3.71V - Thresh07 = 4.0v
CAL08 = 4.28V

But ...

Re: GPS receiver input for data logging?

There isn't a document per say but I can tell you how to structure the can. The custom can is configurable and has 4 16bit words per frame. There are 20 frames, with offsets that start at 600h by default. Each word is spat out in motorola sequential byte order.

I can be more specific with a little ...

Re: GPS receiver input for data logging?

The Race technology stuff integrates well but the software is dog slow to use when analysing big chunks of data.

Re: Sharing inputs

Yes if you're trying to do a blip function on something like a Hawkeye Subaru with DBW throttle, then you probably want to trigger the blip with NPS and clutch switch, and perhaps the brake too if you want you will need to test it to find the best combination. But to share the input with the cut ...

Re: Sharing inputs

What will be easier is if you tell us what you're trying to do, and then we can suggest the best way to do it, or if you're trying to do something "unwise".

There are currently no general purpose software functions or rules that can be brought into play. The blip function is derived from racing car ...

Re: Sharing inputs

Yes and no.

Generally not but you can share an input for the task you want to do. You need to set the "Cut Input Polarity" and "Blip input Polarity" opposite from each other so they reflect the action of the strain gauge. Usually you would have a strain gauge lever sat with the output at say 2 ...

Re: Crank trigger questions, best angle for tooth gap?

That sounds fine. You'll need to remember that the definition for the gap position is effectively in degrees ATDC, and the reference angle refers to the tooth after the gap, rather than the tooth that concludes the gap.

The manual cam checklist is certainly the way to do it, but it's a pain to set ...

Re: GPS receiver input for data logging?

I was thinking of the RWD GTR with Tractive sequential box, Motec ECU mapped by Dave Rowe, but perhaps I've got my cars mixed up?

In terms of logging, you could use the GEMS logger easily as it's CANBUS is fully configurable, as is the Racelogic video vbox pro. The AIM Sports logger is not 100 ...

Re: Crank trigger questions, best angle for tooth gap?

It's not especially critical on a 36-1 or 60-2 setup. However the relative position of the cam position can be critical if you're using a "keyed by single cam" setup as you don't want the trigger edge to be very close to a crank trigger edge (so that it might be either side of it in some conditions ...
