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

Thanks for all the responses guys...

doggy, it really isn't a good idea to run on 95. Sure, it might be fine for a couple of years, but over time he may run into engine problems. Check this:

Robbie from TrackdayPerformance: The engine will detonate on 95 ron fuel. Also it will need to have its ignition map cahnged to run on 95 ron fuel.

Honda V-tec engies will runn for a long time while knocking but after we remap them for no knock they last forever and produce more power as they are optomised for the fuel they are using.

Octane booster will not protect your engine when it was designed for 100+ and you are putting 95 into it.

To remap the toyota we realy need to fit a piggy back or standalone ecu.

drop me an e-mail and i can get some prices to you. robbie@tdp.ie

Well, i really care less about this - cuz im not planing to marrie my car.... Another thing - im planning to run Emanage on the Beams - so i will get to adjust timing and A/F ratio anyway... BTW - if i ran my Turbo setup with CR ratio at 9.5-1 and aint had Knocking issues on 95 - i doubt i will have them with the Beams....
