BEAMS engine remap for 95 octane, Can it be done? Options

[Dagon]

Hey everyone,

I'm new to the forums. I've done a few searches for info on Beams remaps but have found nothing.

Just about to sell my 94 Red SSI Celica with the 3SFE lump, to get a lovely white SSIII Beams machine!!

My only problem is that over here in Ireland it's hard to get anything other than 95 octane fuel. The Beams really should run on 99RON. I've checked out the option of octane boosters like redex, and they seem cool, but would be expensive in the long run, and their effectiveness is questionable.

So the only other option for me is to remap the engine for 95 octane. However, I know that it's a high compression engine, and am not sure if this is a good idea. Obviously performance will also suffer but I'm not sure by how much.

I'm sure some of the Beams heads on this site will be able to help me with this. Thanks in advance for any help or advice from you fellow Celica nuts

you are whong my mate I know a guy localy who is running his Beams almost a year on 95 - and no problem at all. All toyota ECU's are made this way to detect and adobt to the situation and fuel. ofcorse with 98 you will get few more horses, but you can run on 95 without a problem. ECU will retard timing.

My Beams isnt running yet, but i see no problem running on 95.
