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.

 

Oh ok thanks mate

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

 

OR use NF Octane booster when useing 97 ron if you can't get V power

 

sorry to sound like a numptie... but what is it, where do i get it from, how do i use it and how much does it cost?

 

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.

 

Nitrous Formula Octane Boosters

THE BLACK BOTTLE. rcm stock it just shop about look it up on here, but stay away from halfords supermarkets and the like.

 

What years the car? Maybe possible to do two maps on it with ecutek

 

Had concidered that m8, but run out of cash

Maybe next year...... Have decided to get mapd with vpower, and suffer the extra cost, then nxt yr will prob ug to ecutek.

Thanks for everyones replys....

Cheers all.....

 

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.

 

Sounds interesting Simon....could this be done on a MY01 WRX to have a switchable 95 map and a 97 one using ECUTek?
Reason I ask is that I got stranded once near Wales and the petrol stations there had '95 or diesel - nothing more....

 

With these dual maps, do you pay twice, or is the second map at a reduced rate?

 

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.

ok so have decided to get mapd with vpower, but on a slight tangent, how much difference in bhp do Tubular exhaust headers and flow matched uppipe
make? could do with knowing tonight if poss..

 

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

 

oh... oops...
td05-20g
650 injectors
cosworth filter
3" full decat system
walbro 255
3 port sol.
hks bov.

 

Then yes imho decent tubular headers would help power achieved once mapped

 

any idea what i would be looking at as is then with headers?

 

Wrx or sti? 2.5 or 2.0?

20g a proper one or cheap copy?

Tmic (standard, sri or after market) or fmic?

 

20g - propper one.
2002 sti bug 2.0
std tmic

 

phil739 has some good looking gt headers ceramic coated too for sale.

 

lol yes i know, was there yesterday, i bought his turbo and exhaust.. not sure i have a spare 350 though atm... would be nice though..

Not sure what bhp i am looking at with / without them.. any ideas?

 

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.

Not looking for 400 tbh, was hoping for 380 but will i get this with std sti headers?

 

Yes you can make with STi headers and better up pipe(but yours is all ready decatted),which will help you to better spool up as Harvey sell.

Jura

 

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.

 

tbh i dont understand things such as less spool, just want a nice fairly quick car putting out 380 ish.. that will do fine for me.

will def. put on fmic within 6 months though, if not only cos they look awesome lol

 

Less/bad spool mean or nice spool mean this,with less/bad spool you will be have laggy car,which can be pain to drive,yes will make power but in high rpm.


Jura

 

Ah-ha got it
So what would be the best mod next to help spool?

Once ive paid off my sredit card i recon by xmas i can start to bung some more cash at it again

 

Hi there i would contact Harvey,which selling the Up pipe which will help you gain spool(cost around £145) and if you want ported headers,he selling too.
