Whichever way I decide I will be budgeting for a simtek to delete that pesky MAF tho!!
Does anyone know if they have released the update for the Simtek? Also whats the deal with Knock detection/protection? I've read that they can use the check engine light to warn of knock but was a bit confused as to wether it did anything about it?
Cheers

How can anyone say p1's are not prone to engine failure, I would say most have had a rebuild before 50k, looked at many cars that had all been rebuilt then just bought an evo, back in a uk turbo now as a daily runner for work.
What's the deal with the fuel, I run mine on 95 unleaded, tenner at a time so is always nearly empty, do I have to stop being tight and put better fuel in?

Nope, just keep doing what you are doing and keep my phone number on you at all times.
Good luck, [ you'll need it ]

I just don't understand why people get the cheaper fuel. These cars actually run more efficiently on the better fuel and in my experience it's enough of a difference to make up for the difference in price.
Oh well.

Two things really:
One is surge in the tank, when cornering on low fuel level, the system picks up air which shortchanges the injectors momentarily.
Second is that the returned fuel from the injector rails spill off is hot and that increases the temperature of the low fuel level in the tank. So the fuel tends to get hotter and hotter as you run low.
Keep a decent amount in the tank and the larger quantity will cool the returned fuel rather than the returned fuel heating up the tank contents.
We advise customers in our engine rebuild fact sheets to treat 1/4 tank as empty. Running lower can be dangerous.

Just wondering as many years ago I had an engine fail only a few 100 miles after a service and was convinced the 2 were connected however the garage (main stealer) at the time wanted nothing to do with it and adament it was nothing to do with them - plus it was JDM so they didnt give a hoot.

They're essentially the same as the Type-R just extra knock factoring in the map IIRC.
And this particular one had the all important rebuild around 25k ago so thought that this would have covered the bases, unfortunately, it didn't!!

I'm worried now. I've just bought a 95my wrx, and have been running it on sainsburys 97ron as the previous owner told me it had been mapped to do so with a piggyback chip, which I can't remember the name of (polas or something - anyone?)
How do I know if he was telling the truth? I do have a RR printout showing car giving out 278 bhp which is more than the 260 it should have, but wonder if this is down to the full RCM exhaust?
Someone calm my fears please!

Not sure on the piggyback chip, AFAIK there are different types of chip, solder in chips or external 'piggyback' like the old unichip, (not sure if these even exist anymore!!?) or then theres a fuel computer such as an Apex'i AFC?
I would of thought you would achieve more power than that with a standard remap, unless it is just purely been re-mapped for 97ron.
I'm sure someone with more technical knowledge will be able to advise in a bit more detail.
Either way I would get it checked by a reputable tuner/mapper of which there are many on here, just to be on the safe side!!

Easy enough to check. Pull back the passenger carpet, remove kick plate and ECU, look for anything that is hanging from or connected to the ECU (apart from the yellow plugs). Once removed, undo the 3 brass screws on each side, remove lid. You should see some thing like:
Note the code on the lid, Z4 in my case. Also in the bottom right hand corner you will see the DIL socket where any chip will be fitted.

had the ECU been re-mapped at any time during it's previous ownership?
I believe the P1 engine was a V5 STi unit with octane booster "tablets" suspended in the tank? (Bouquet???) to satisfy the Japanese map? These "tablets" were sacrificial and once disolved, left the fuel below the octane requirement of the map. If I'm in error here, I'm sure someone will correct the above information?
If the OP finds that no re-map was done, that must be a priority as soon as possible after the re-build. Also - always carry a bottle of NF or similar in the boot in case the only petrol available is from a station with a green logo!!

Broquets were claimed to be able to last 250,000 miles if i remember correctly .... they apparently reduced temps and improved emissions ... and also claimed that they reduced knock but not sure if this part was ever proved conclusively
I think it is generally accepted across the board that Ulitmate is NOT good for scoobies
Shell claims average of 99.2 RON at the pumps ... Id never use anyhting other than V-Power ...
Ive now clocked 85k in my P1, owned her from 15k, standard and still original engine (.... touchwood lol!!! )
Good luck sorting yours fella ...

Well the plan is to go Simtek, so MAF less and mapped by Bob Rawle.

Well I have spent many a day with my fuel light on BUT I drive like a wuss so no problems caused there then! LOL.
Of late I have been filling up a lot lot sooner but still do not understand the 1/4 tank thing. Is this mentioned in the handbook? If it is such a severe issue.

No it's not in the handbook. But research here and at other tuners has thrown up the fact that almost all of the cars that arrive with a blown bottom end, have NO FUEL in them. We sometimes do not have enough to even run the car for 1/2 an hour whilst it is warming up after the new engine is fitted. I doubt if we ever see a car in for rebuild with more than 1/2 a tank in it.
It wouldn't look good in a ' handbook ' [ who reads them anyway ] to say that the engine might fail if you run low of fuel. Not a great publicity plus point.
