Hi everyone, Got the coupe on the rollers at Perfect Touch recently. Mods at the time: Panel Filter Pace SMIC Peco Catback Baileys Recirc GTECH 1 PRV Autometer Pro-Sport Boost Gauge Rog @ PF set the PRV to a smidgen under 16psi for me (confirmed on Autometer Gauge). 16psi ~= 1.1bar. Here are the results. Power/Torque: http://i242.photobucket.com/albums/ff259/warnysouth/rollers1.jpgAFR: http://i242.photobucket.com/albums/ff259/warnysouth/rollers2.jpgRob said that he thought the fueling was spot-on and that the lack of power is probably down to the ECU retarding the ignition. At the time I was running 90% BP Ultimate, and 10% 95RON. I was annoyed, as I had intentionally filled up with the BP fuel! I had no idea it was considered 'inferior super unleaded'. He said I could expect up to another 25-30bhp with 99RON or such like. Graph says he used 4th, although he told me he used 3rd? I didn't get a boost graph as Rob used the gauge in the car. Was pretty happy with PT, Rob was very reassuring and answered all my questions. He also took note that I did not wanted him to be extra careful with her! Any thoughts/comments on the results? Looks pretty similar to Austin's results I thought. Thanks, W

Hi, Your results look very close to mine in Power/Torque although your AFR looks much better. I was running 95Ron at the time and I'm wondering if the gtec map switches over to the higher fuelling map at a certain boost? e.g 1.05 could be on the 'leaner' map whereas 1.1 Bar could be the 'Richer Map' if that makes any sense. Have you felt any differecnce now you are running 99ron? Austin

Have you felt any differecnce now you are running 99ron? Austin I'm sure there are people on here that will be able to comment on your question about the ECU switching maps. Maybe GrahamL/Rob(PT) etc might be so kind as to tell us more about how it all works. As for the 99RON issue. Its very hard to say. Maybe a bit of difference yes. But after my split hose the other day I've been relucant to push the car hard. I would like to go back to PT after doing the fuel pump mod and with 99RON, but they are quite expensive and its a long way away. Cheers W

you should not use 95 ron fuel with g-tech chips

I'm not convinced I would see any difference with 99RON over the BP Ultimate 97. It might be that my engine, being quite old and been round the block a bit, is just a bit down on power, and 220bhp is all I'm going to get. The assumption that the ECU is retarding the ignition, is just that, an assumption (unless anyone can explain how to verify it)? Quite happy with that btw, and dont want to waste more money finding out

just putting higher ron fuel in doesn't make your car faster, it just means you can run more advance (from a chip or live map) which = more power

Exactly. But I have no way of telling whether the 99 over the BP ultimate which actually yield any more ignition advance. Its an expensive question to answer

99 ron is the best for mapping & will give the best results. it's hard to tell how much, maybe 5-10 bhp

Hi Ash,
Well I'm running Tesco's 99 RON at the moment. Car feels very quick (1st gear is manic). Not sure how MPG is doing. Need to do a full tank.
Cheers,
W

i agree with ash, i was mapped at PT with v power & used it before the the mapping

99 ron is the best for mapping & will give the best results. it's hard to tell how much, maybe 5-10 bhp Well according to PT its up to 7 or 8 bhp per degree of ignition retardation, and the ECU can potentially pull it back by 3 or 4 degrees. So thats 21-32bhp potentially.

So then you would be running the normal gtec 1 power of about 250. Bess keep putting it in, more power Well I'm not using the BP stuff anymoe, terrible MPG on that and Im not using 95 , so its v-power or 99 for me! . Always suspected it but assumed that if it were rubbish, they wouldnt be able to market it in the way they do?

mine runs best on tesco 99ron, even better than v-power for mine. i remember i think it was 5th gear that did a test of fuels and they used a standard scooby wrx, the difference between the 95ron and the higher octane, can't remember if it was optimax or v-power, think it was optimax, was about 30bhp!!! that was on a standard wrx!!

but as in my other post below, the impreza has an ecu that can adapt to the different fuel. The 16vt and 20vt's can not do this!!

i was expecting slightly better spool & slightly better top end from the ultraspool, but i have no complaints how it drives on the rd, it just pulls & pulls & is very smooth.
if you look on my graph, the temps were quite high on my run,i'm going for another rr soon & i think i will hit over 300bhp.
good luck with your rr session,are you just having a power run, or being mapped? look forward to seeing your results

but as in my other post below, the impreza has an ecu that can adapt to the different fuel. The 16vt and 20vt's can not do this!! Yes, but the ECU can select whether to retard the ignition or not depending on whether the knock sensor is triggered. So in my case, with the gtech 1, the ECU *might* be pulling the timing back as its too aggressive for this fuel. If I switch to 99 RON, it might not retard it so much, and then I got more power no? Is the GTECH 1 only a modified fuel table or does it have a modified ignition table too? Thanks W

The Gtec 1 is designed to run on the std ignition and run on 95RON, so putting in 99RON and running a Gtec 1 is not going to yield you any more power.
The knock system works but detecting knock / pink and will retard the timing by X degrees for X amount of engine revolutions, then it will go back to the orignal ignition advance and carry on as normal, until it detects knock / pink again and repeats the above process.

OK thanks Begbie. So that's it then, 220bhp is my lot for this boost pressure (thats another thing - I wish they had given me a boost graph - maybe the 16psi on my gauge is only 15psi - that would lose me a few horses no?). In Austin's case he might get more when he sorts his lean mixture out though correct?
Cheers
