Default Re: Running Pure Meth - Use UEGO as failsafe?

I would like to add on what is already discussed in good details by Rice Racing (Pete of RR).

As the concept of water injection was made popular over the years, many companies has jumped on the bandwagon but lost some of the original focus of what is the order of priorty, this is where marketing has taken the industry in a wrong direction.

Like Pete (RR) said, the job of a water/methanol injection system is to inject water reliably and predictably.

This is exactly your point of mentioning AEM's new flow monitoring system for water injection. Why make the effort of monitoring every CC in a delivery system which is fundamentally flawed. Looking at their flow curve against duty cycle, does it in any form shown any linearity? In some areas, there is non-linearity error of +120%!

Imagine someone trying to sell you a car with an engine temperature gauge that is accurate within a few tenth of a degree rather a car with a properly designed engine coolant recirculating system with a simple temperature gauge.

You do realise the momentum of the bandwagon, no other wmi makers other than RR and aquamist have taken the effect to address the basics of a wmi delivery system. They all opted for controlling flow by vary pump speed (PPS system) and uses slick marketing to cover-up the non-linearity and limited dynamic delivery range.

A typical PPS can only vary its flow from 100cc to 200cc/min with a pressure change between 60psi to 240psi with linearity of over 120%. You are one of the few people that raise doubt and start questioning behind the smoking mrrors.
