How do you tune with 50-50 mix?
How do you tune with 50-50 mix?
Just curious as I may get into this down the road. Does this change my AR's when running it? Say I am seeing 11.0 at wot and install a kit will this change? For now I am happy just running race gas but it does get expensive!

anyone initially approaching AI asks this central question...
most are surprised at the correct answer. you tune for a normal AFR. if, for example, 11.3 works pre-AI for you then tune for 11.3.
this is not to say that with the addition of AI and your prior tune you will see similar numbers. you won't. you will be rich.
if you do not retune after adding AI you will not garner it's many benefits.
of course we all may not have the same objective w the re-tune... some may just be looking for zero knock and happy motors while others may be looking for major hp gains.
here's the sticky on the subject:

Also when you take out pump fuel and add boost you put yourself a dangerous position if you loose the AI. See safe-guards thread.
I left my unassisted waste gate row (12psi) fat with fuel. For the electronic boost controled rows above I use a relay to energize the EBC solenoid. No AI pressure. no increase in boost.

Would this trigger the safeguard if the tank runs out of the pump stops working? That is a more likely scenario than getting a clogged nozzle. I have been running AI for over 3 years and have never had a clog..

Radkins, Thank You. You inspired me to include a simple safety device in my AI system. ,
Don't be thrown off by my using the clog nozzle switch to activate the boost control. If that switch doesn't see pressure be it a bad pump, bad pump connection, or low/no fluid in the tank, the boost stays at spring pressure of 12 psi.
The clog switch function must also be monitored, ie. it should go out as soon as the throttle is released or the nozzle is starting to clog.

This is great!
I think this information just pushed me over the fence for the AI Investment
Great Information!
