Can your WI system be used on any ECU?
Do you think you will keep increasing the boost pressure? or are you going to stop at a set amount? or is down to when you start breaking things, as always happens when gaining in HP.

Hey Mate,
My WI system can be driven off any ECU that has a PWM table and switching conditions table settings (or you can use it stand alone obviously).
I did a quick test yesterday after recalibration of my MAP sensor to match the Blitz I Color and on board internal MAP sensor in the ECU. Had to re tune the car! but basically on 180kpa gauge ~ 280kpa absolute (26.3psi or 1.85kg/cm) its accelerating harder & faster than ever before! its just unreal to me......... the thing that really gets me is I have a full computer full of logs and tests from this car, its just flat out unreal how many tests I have done with it over so many kilometers covered and YEARS!. I think as I wrote a few pages ago what I am doing now is what I thought was a limit before, and this is like the first boost control setting!
I have a local dyno competition in February that I was going to run at last year (remember it got flooded out!) and I will just leave the car as it is on 1.85kg/cm as its proven and I have lots of information from my power measures of it and see what its like on their system.
In the cooler months (remember its middle summer here) I will run out to the higher boost settings I experimented with last year. These will only be able to be used in direct drive in 4th gear on the OEM gearbox,
I will run it to 2.45kg/cm or about 35psi gauge boost pressure all indications are it will do it easily as the new water injection system specification by theory and practice to date is allowing such unheard of numbers without raising a sweat.
Once there that is it for this set up. I have no more capacity in this turbocharger nor many other components, but honestly what it does now on 1.85kg boost setting is totally amazing (its proven to accelerate faster than any super car you can buy, and has an
acceptable top speed of 210+MPH!!!!), I say again I have NEVER tested nor seen presented to me in any
legitimate way ANY RX7 in the world running a 13B engine of any configuration on normal pump petrol that will accelerate like what I run everyday........... and the proven world leading durability I have proven here is unmatched by anyone period.
