Thank you!

I think I've concluded that Superchips maybe fine, but not on my Scooby!

Hi Folks,

How can you tell if the car has been superchipped?
Any signs inside the ECU? (I.e. signs of soldering etc etc?)

Regards,
Simen.

CraigRA what boost did they set the chip to run at? im presuming you have a type RA import? i heard that safe people who fit the chips are cautious of imports as theyre mapped for 100 ron fuel, if the chip is set to 17psi and 16 held on a uk car surely there must be enough fuel going in to be safe as theyre rich running?

i mean i read on here about people running 18psi safely? so if the chip is set to peak at 17psi its not going to spike much more than 1psi is it not????? realy not sure but im sure somone will tell me!

Imports are a completely different kettle of fish. Some are actually detting without mods unless you run 100RON. Add a downpipe, extra boost and a hot day and you have a recipe for (potential) disaster.

Compare with a car which runs safely on 95RON even decatted, put in 100RON and then run more boost and you can see the difference.

Also note that imports with bigger turbos flow a lot more cold air for the same boost pressure as it is not overheated by a small turbo and intercooler, so the fuelling requirements on a big turbo at 17 PSI are much higher than a small turbo at 17 PSI (colder more dense air).

Cant remember what PSI it was set to but it went something like this.
Got an import 93 RA, will it work ?, yes says the supplier, what you have to do once its spliced into the loom is open up the case and put a meter from point (A) to point (B) and turn the adjuster until you get reading (???) on the meter and this is the correct setting for your car, set the bleed and your off.

Before anybody asks yes the advice was from a so called Scooby expert, and yes it was fitted and set up by someone who is in the know (they prep Le Mans and touring cars).

Sory to hear of your misfortune, but how many Imprezas do you see as Touring cars or at Le Mans?

guys:

had mine superchipped 6 months + ago, all running fine.
engineer who fitted said that as long as UK model & no silly boost & no long track days etc, then it will be ok. He reckons no higher than 17psi.
my engine mods are:
full magnex including downpipe, KnN, superchip...had absolutely no problems at all. Been running on Optimax nothing else.
However I had the chip fitted then discovered scoobynet, to find that superchip not recommended. I have stated in a previous post that if I had the choice again & was looking for high boost & keeping the car for a while then I would have saved up & got a link, motech etc, more tuning capabilities & reliability.
"horses 4 courses" I suppose, superchip does me for road use.
I am in no way technical btw, & remember getting very good advice from Evil (theo) & others regarding this

You could always fit an HKS fuel cut defender which only lifts the fuel cut and use that instead of the Super"chip". Or consider one of the circuits doing the rounds. This would remove a lot of the safety concerns of boosting to infinity if a hose comes off or splits or the wastegate sticks. This is my only real objection to the Superchip to be honest if sensible boost limits are kept to as your installer recommends.

Scaramanga,Ozzy and Scoobyjawa,

Seems as though you're all agreed on two things:

1, Changing the BB to a Prodrive (reasonably quiet and civilised option ..?)- Do you have to go there to get it fitted and any idea of cost?

2, Changing the Panel filter (any particular one? and cost? easy to fit?)

... and not quite on
3,
The Dawes option seems to be good if one knows what one is doing, but Ozzy has reservations clearly. I read John banks accounts who seems to swear by it ...

Scaramanga,

I've heard interesting things about PE - buddy has a great Cossy (400 BHP plus) and warned me away from them. When I spoke to PE, they said the ECU chages hadn't been quite cracked yet for the MY00 ...

Cheers

Tell me more about your overboost problem.

Hi all,

I was really keen on a Superchip until I started this thread and read about the Dawes.

My aim is to get a quicker low down response ... more torque pre 3,000 revs. The Dawes, from what I have seen, achieves this and holds the boost at a more consistent level for longer ... John Banks acheives 18 PSI from 2.5k to 4.5 and is still at 13 at 6.5k from his car with the PPP too (which must add a couple of PSI through out surely). Bearing in mind the standard MY00 peaks at about 13 PSI (I think) - this is pretty impressive for a £40.00 device, a couple of gagues (how do you spell that?) and restrictor valve!

Couple of points (I'm not a techie as I'm sure you've guessed!).

1, A simple manual system, Dawes in this case, which is not influenced greatly (as I understand it) by what is going on around it too much i.e temperatures, aggression from the driver, etc - seems to aid a stable boost control. Anything electronic which is ''Thinking'' could make a poor decision?

2, The Superchip (or any other simple ECU upgrade) seemed good on paper, but when the fuelling and timimg issues were exposed, clearly there is a (I guess) greater risk than the simple Dawes option. As long as you control your boost - John suggests standard MY00 fuel cut off is 17.5 PSI, so max boost set to 16 PSI leaves a good safety margin - then I guess, all should be fine ...!

Oh, and its cheaper and easier to control yourself than an ECU upgrade.

Trout,
If I want to push the car further, then that's a different matter. Exhausts, ECU and goodness knows what else will be considered at that point, but currently as a new boy at making things go noticibly quicker than the factory brochure suggests, I'll have aplay as you suggest - ITG filter, Dawes and a BB ... anyway, there must be a sensible limit to what you can do with a car that only retails at 20k or so .... surely??

Look forward to being shot down in flames for my limited understanding and oversimplification ... but I'd like to hear!

Steve

Dont fit the Superchip, I made the bad mistake of a cheap quick power hike with one of there piggy back chips and a blead valve. It went well for approx 60-70 miles then blew the engine up big time!. They adjust the boost but not the fueling. It cost me a £4000 pound over price rip off re build at Bill Gwynne's. If your going down this route a proper mapped ECU/engine management is what you want.
