ECU CHIP?
 
Hi everyone,

I have just purchased a 94 WRX type RA and was hoping somebody with a lot more knowladge than me can help me out. Im from N. Ireland and our highest rated fuel over here is 97ron and im a bit concerned about that as i know they dont run the best on it, ive been using Millers octane booster the few times ive been driving the car but ive read that a chip can be put in the ecu that makes it safer for uk fuel and generally makes it run better. According to what ive read so far a polar performance chip is the way to go but i cant seem to get one anywhere!! Is there anyone who sells a good chip for my car? Took the ECU out yesterday and its a z5 4 plug ecu and when i opened it up it seems to have a blank board for a chip already there. Any help would be very much appreciated.

Thanks

97ron super is just fine it's unleaded 95 is a No No shell v power is 97 I think it's only tesco that doe's 99ron but I may be wrong

Thanks for getting back to me. I wasnt sure if the 97 ron was high enough as i know these were mapped on 100 ron in Japan. Was just concerned about detonation problems and didnt want to ruin the engine. Have been using the octane booster but i know there must be some sort of chip out there for the ecu mapped for our fuel. No optimax 98 ron or tesco 99 over here.

get an esl board fitted and mapped its the best and safest way bud. the chips are normally flashed for specific mods and u would have to know which mods and make sure u have the same ones ie a front mount ic, walbro pump, 440 injectors that kind of thing. if u dont have the same mods it will run like a bag of nails most likely and probably cause damage as the fuelling etc will be all wrong.

97 wont be high enough for an import RA (all RA are imports), best option will be an esl chip and map.
