I think some of your are misreading how this works. If I switch off the dds at WOT, boost drops and I switch back to my basemaps instantly. Instantly! And yes, if I have the dds off, go WOT, then turn the DDS on, I stay on my base maps until load goes down, then it switches to the alt maps. The reasons for this were talked about in your posts though, we don't want the car switching to base and alt maps back and forth rapidly! As it is....it works!

 

i understand what your saying bro, the only point was making if your pounding thru the gears on your alter map, and your DDS picks up some type of failure while @ WOT. How would it switch to your standard map if your load threshold hold is 110%?

 

As Tephra explained, switching to standard (base) maps is instant REGARDLESS of the load value. It's a one-way thing ONLY affecting switching to ALT maps.

 

OMG I totally forgot, my bad fellas. Sorry long morning @ PT

disregard what I said before, man I'm slacking lately

 

Damn slackers,lol JK

 

Just wanted to bring up a question with regards to the load threshold for switching to ALT Map. If you set the load threshold to say 100%, and then while flooring it you turn the HFS on, it will stay on the SAFE map even though you are spraying meth. Is this really ideal? You will be spraying way too much fuel.
I understand the concern with oscillating between maps if the failsafe is on the fritz but its also not great to be spraying so much meth if you are going to be on your SAFE map. Also couldn't you avoid map switching oscillation by using the map switching delay timer?

What have you set your delay timer to?

 

What you're trying to avoid is the rapid increase in the ignition timing. That can cause a world of issues. I'd rather have too much fuel than a blown engine. If you WANT to bypass this, just set the load threshold higher than your maximum load value that you see when logging.


I'll be designing and testing my own custom alky kit within a month or so so I'll be able to really fine tune the V5 functions to work in conjunction with an alky kit.

Anyone who replaced their ICS system with alky, you should be able to use the output of the ICS activation wire on the ECU to trigger the alky kit, rather than a boost switch. This way you can set the alky kit to come on at any load value you choose. Say you set it for 180 LOAD, you now know you don't need to alter any of your fuel map from 0 to 180 which will make tuning the transition between straight gas and alky a LOT easier. Give me a little time to really tweak some stuff.

 

How do you have your HFS setup? The boost input should remain on until the control detects a failure. Once a failure is detect it turns off the boost input which ='s no voltage to the ADC channel (standard map). So cruising around with no failures you will be in your alt map. So using the HFS with tephra v5 "stock" settings are fine. Now if you had a setup like mine that uses a pressure switch yes it would be a concern. I had to set my load threshold to around 250% and the delay timer to 50ms in order for it to switch rapidly.

you can setup a new MUT request to log 0xFFFF8425, if its 0 then you are on standard maps, if its on 3 then you are on altmaps. The evoscan address below is requesting ID 08, so I would go into my MUT table change the value thats was currently there to 8425.


To log ADC voltage

0= 0 volts 255=5 volts

 

Jack_of_Trades - good call on the timing, I forgot about that.

Personally I have altered my HFS so that the delay for triggering boost cut on a failsafe issue is a bit longer, this eliminates potential failsafe oscillation situations.

I do love the idea of triggering the meth kit using the ICS signal. That is a great idea which I may try to implement with my current system.

 

ohhh gotcha, well good luck man

 

nice work on the vid

 

I'm actually going to start offering an Alt-Map harness specifically for use with the Aquamist HFS-1 this week (just like schiedes has installed) for anyone interested. It will be cheaper than the standard Alt-Map Harness' too

 

Awesome jack_of_trades!


I still LOVE this setup. I have been playing with various pump gas/pump&alky tunes, and it is still amazing to me how much more power can be had from alky. I'm installing my 1050cc injectors on sunday (hopefully) and should be hitting the dyno very soon!

If anyone has any further setup questions about this setup, please feel free to post here. I get several PM's, and answering them here in the public eye generally serves the community better!
