26th us good for me

[scotty nm35]

Pizz up at Jez's shed. All invited.

[PN-Mad]

aheemmmm.... might just have a RDO on the 26th.....

Scotty your car isn't invited. It drinks too much booze

[WAGON_BOY]

come up then i dont mind and i'm sure Jez doesnt either.

[DVS JEZ]

Of course not. Make sure shaft is removed ;p

[WAGON_BOY]

i got the instruction manual for the wideband i want to make sure it's going to be useful before i get it.

"The Bar Graph Display (BGD) Range Setting Mode allows you to fine tune the resolution of this instrument for your specific application. With upper and lower set point adjustability, you can set the BGD to utilize the exact range that the engine / vehicle operates within and see exactly how rich or lean you are running in relation to your current set up and tune. Adjusting your BGD limits also adjusts the scaling of the 0-4v data logger output supplied from the gauge. The selected low set point of the BGD Range becomes the 0v value of the data logger output. The selected high set point of the BGD Range becomes the 4v value of the data logger output. Whenever you change these points, the instrument adjusts the data logger output so that the 0-4v signal is always linear between your chosen set points. "

Looks pretty good Theo. WOT input looks interesting, mine doesn't have that. Although the Innovate's have a built in data logger, whereas the Auto Meter seems to want one connected (which is probably the output you'd use for the F-con).

But at the end of the day it depends on whether the tuner wants to use it constantly, or whether you just use one of those ones you can stick in the tailpipe for the day.

My dyno has its own wideband that logs afr to the graph.

I have 2 standalone widebands that can be used for datalogging or roadtuning.

I recommend putting the wideband in for piece of mind, can then see if u have a lean out etc due to fuel surge or fuel pump failures etc

[WAGON_BOY]

shaft is out, oil is changed and a full tank of fuel ready for the dyno

[scotty nm35]

Keep us posted...

[DVS JEZ]

Howd it go today Theo

So all ur worry was a false alarm, the 02 sensor reading in the cypher software the Alex was reading from has no bearing on what the actual AFR's are. Tune was fine except for the 1 area which u heard a ping at low rpm high load which was very difficult to replicate on the dyno due to the auto but i found it and fixed it.

Ps, nice single pegger skid when u left

Very interesting today Jez- so we know stock ECU > Theos aftermarket computer> motor.

And I can only read what the stockie puts out.

Had a great run coming back down the old Pac- volvo convoy.

Nice

Yeah was very weird, especially how much difference there was in the ignition timing output from his aftermarket ecu to ur software

[scotty nm35]

So second tune and no gains? C'mon Theo, slap a Hypergear in there...

All the stock ecu does now Alex is run the throttle and cams, nothing else has a bearing other than to keep the MIL away. I have no idea what signals the Fcon sends back to keep it happy but whatever it is, thank you mr HKS.

[PN-Mad]

Jez also found some little parts of the pre-loaded tune that were no so good - and sorted them out.

I've got some logs from the power runs. Might load them if I can be stuffed

[scotty nm35]

That's why I wouldn't use maps designed for other cars, you will always end up chasing gremlins in the tune imo.

Post them up Alex, I would be interested to learn what the Fcon is doing to the stock ecu and that may hold the key. If I end up going down the Link G4 route I may need the same signal bending output maps... The manual transmission will open up a world of possibilities.

[DVS JEZ]

Honestly i wouldnt trust the log files as even the timing etc is way off

[PN-Mad]

Exactly right.

As I said it goes Stock ECU > aftermarket>engine.

So Ign timing is not correct for the engine, but other things like Cams, AFM, and BFS are all able to be seen accurately.

This is a screen shot of the log, unfortunately it won't let me upload the exl file....

Cant see it on my iphail. Will check it out later
