remap - different fuels
just a quickie.... having an open s. map done this week, if its mapd using vpower, will it damage the engine if i use it every now and then on 97 ron?
reason being shell station is a good drive from me, but the station at the end of my road stocks 97. would want as much poweer as poss from the map, so would prefer it to be mapd with vpower, but on average i would say for every 1 tank of v i would be putting in 2 or 3 tanks of 97...
coments please... Cheers.

Map for the lowest octane fuel you use most regularly. And stick to using that fuel and quit swapping between differnt octane fuels.
If that's 97ron, map it for 97ron. Then if higher otane fuel is used, no damage or harm will be done.
Mapping for 99ron without enough knock correction could potentially wreck your engine if used on lower octane fuel.

So i will have it mapd for 97, if i put in 99 at any point will i see an improvement, or wouldnt there be any point in using it? and simply sticking with 97

I thing it depends on the ECU.
A recent conversation about maps restricts the cars fuel choice. So if you map on 97 Ron from a supermarket, then switch to V Power then there will be no power increase as the car is mapped for the other fuel. People are going to say different and say that the car will auto tune and give that bit extra on the new fuel, this depends on the ECU and software used to map it, most wont. In the ideal situation you have a vpower or tesco 99 at the bottom of the street, or the worst case you go to halfolds or even a supermarket and but octane booster and keep it there , just in case you cant get to the petrol station of choice.
Yes maps can be that finicky, so choose you’re fuel carefully. Some will not sacrifice the power and want the max and therefore will map on the highest grade fuel as the car is not an every day driver, the choice is yours.

Mine is mapped on either V-power or Tesco 99. If I have to put anything else in the drive like the film driving miss daisy. A while back had no option but to put 95 in so drove off boost, then when filled up with v-power drove on reduced boost till next re-fill. Before anyone start ranting my car has covered 10K miles since then and is now putting out 441 bhp on the clinic's rollers. The engine internals are still as came out of the factory. For Now, roll on 500 bhp.

On the hawk onwards (hatch and new saloon too) yu can have two complete maps so could be setup for two fuels. No extra cost.
On the earlier 01 to 05 is possible to do similar but not full maps.
Pm if interested and I will explain, dont see giving away all my ideas.
Would require one mapping session on one fuel and a check and possibly a tweak on the other fuel. Only extra cost would be travel expenses or dyno expenses for the second fuel.

You havent said what turbo and other mods you have but generally around 10% gain or rather it ensures you should get what it should make. Needs to be decent 3bolt style headers through which are not cheap

Under 400bhp headers will rob you for spool and with 20G you will struggle pass 400bhp without the meth,yes some will tell you he make 400bhp+,but is big but.
Two proper fuel maps on 02 is not possible,due few things,yes is possible have two boost maps,which can do Open source mapper too(here is few which have excellent reputation),without the going expense to EcuTek.
EcuTek have recovery mode,which is only good if its your ECU is bricked after aborted/unsuccessful remap(which is rare),which can be recovered.

ported headers would be ideal, i was going for the same spec as you but decided to go with the v48 and ported headers plus meth mix as i aint looking to sacrifice spool.
