right you are max.
I have a back box, downpipe, induction, intercooler, and I am running way too rich on base map. I need to get Tim to set it up.
My mobile 4 gas measures a/f too and is supposed to be really accurate, so I think me and Tim might go bombing up and down Salisbury plains and tune it that way. Got some lovely roads down your area I ws down there the other week but too many cops for my liking.:)

Regarding the fuel cut, I think the only time when you see fuel cut is under max. load and max boost, or isnt that right.

The Apexi acts as a Fuel cut defensor as well - so no fuel cut. Your injectors will pump right up to the limit, but will probably melt eventually!

You will get a warning light flash on your dash to tell you when your injectors are maxing out.

You do not want to run injectors past 85% duty regularly.

The only cut you may experience is boost cut, where the boost goes beyond 0.2 bar higher than what you wanted it to be. Feels like running into a brick wall and very violent :(

Brian :) I have a great section of road nearby where I can do logged 3rd gear runs all day without much trouble, even 4th gear runs (just). Its fairly straight, two miles long and no junctions - lovely....

should come to my place, a 10 minute drive and then you are in germany. You can do 175mph all day :D

Can tell you from my experience that it is fast:o

Think that tonight I\'m going to check how my cat looks, anybody some hints on how to disconnect the cat etc. easiest way.

The stock ecu on a rx7 is also mapped for 100 octane fuel so it makes no difference. If the apexi is bad ofor us because we only have 98 octane then the stock ecu is alo bad.

Brian, what about us UK owners, we are mapped for normal unleaded. ;)

Hi Dan,

Through asking lots of tuners and doing lots of searching on this I still have not found any suitable answers with regards to proof that a few octane makes any difference to reliability or performance of a rotary engine  whether a UK car mapped for 95 octane using 98 rin is fine and a japanese mapped 100 octane using 95 is fine. I was suprised to fond out myself how much jap spec rx7 owners over here use normal uleaded. I think the main arguement is about heat and pre-ignition, I can understand the reasons people state in theory but still have not seen or found or heard any real evidence to back the theory up.
