Fast Idle Install

I asked Jason to upload that one today.Erik712m wrote:Alan, None of the videos really explain the Idle. The only one that would. Would be of the car wash with your feet out the window did no one video?
The ones with the angle indicator are me going up a steep bank. Not as clear as if I had the tach in the same video, but it's absolutely the "off road cruise control" effect. You can hear the RPM does not even drop.
Except for having the carbs talk to electronic gauges on a laptop...For the most part the videos you have posted. none really show anything different, than what the pinz even with carbs can do.
And the one in the ditch, where I'd bog it almost to a stall, then run up the bank. Yes, hard to tell from video, but it'd be very hard to do that repeatedly with carbs without a backfire, stall, etc. You were the videographer!
Next time I head for hill country, we'll idle up the mountain with the video running..... there is one spot almost 45 degrees. We've been busy with the commercial install, but with that out I'll try to film some more.
Even super steep hils are not as hard as whoop-de-doos, curbs, and parking lot stops, as it's much harder to have the controller add quickly, then back down as you go over. Without surging, etc.
Have fun,
Alan

Alan, lets get some RWHP and AFR data from this puppy on my chassis dyno.. You could get some video of the dyno run that may help illustrate how the FI performs under load at low RPM as you should be able to pull from 800 RPM in 5th gear on the rollers clear to redline.. They only weigh 5,000 pounds (and a VW engine can do that with carbs!)
It would only take 30 minutes to get the numbers and I won't even charge you..

do it!!! I'll be in the area for steal soldiers in August I bet my stock pinz minus carbs could do the 5th gear pull. Lets show the VW group how the real Aircooled was suppose to perform not that copy cat oil leaking engine Alan you know you'd make lekwana proud. And I know I spelled his name wrong! I have had to much to drink to night to even find the write spelling.

Whats so big about that? I've been able to do that since my first dyno session well over 3 1/2 years ago. The off idle and crawling were the easiest part of the mapping with the stock engine, it was the midrange that took a bit more fine tuning
I used Calico for all my crawling trials as you can see by my avatar.
Proof that you can drive an injected Pinz on one wheel and still stay running flawlessly

Jake, that would be fun. Do you have a way to easily vary the load? IE: Like whoop-de-do's? (multiple sharp 1-2' hills, boulders, etc)
Jim, what Erik has seen & is commenting on is far beyond just a nice, strong idle torque. We had that with the Gen 1 in Herbert's "Green pickle" pinz. What we've implemented with the current production is actively managing air, fuel, and spark all in conjunction around a target idle.
Think traditional closed loop idle but on steroids. Normal closed loop idle goes temporarily lean with large air changes when bogged, as they do not trigger an accel shot as there was no a pedal movement. And this is entirely separate from your normal fuel & spark maps. Takes way more granularity than just idle control to avoid bucking, surging, etc around large air movements. Increasing & decreasing. (See above on the states)
I know you won't believe it until you drive it, but I can say with authority that the EMS & Hal-tech controllers do not do what I'm talking about with their IAC modes.
The closest analogy I can come up with is a cruise control at idle speeds. That'd be about the only way to duplicate what we've done, and that's about how it works, up & down embankments, over boulders, etc.
Have fun,
Alan
