As for a pre 96 car making 272 at the wheels with a generic postal map, well that equates to 340-350 flywheel hp. Your MAF will have saturated well before you encounter the sort of loads required to reach that target power and if you are on standard 380cc injectors they will be very much in excess of 100% IDC. I'm not sure why the car in question needs a manual boost controller as the boost target and solenoid duty is easily mapped using a JECS ecu and daughterboard. In short, it can't be done with just exhaust, filter and chip mods. I guess you could buy an Immortal map and ask for a refund if the that particular target wasn't acheived
I thoroughly recommend Andy at ESL and his boards, I bought into the first GB he did almost a year ago. Ran my 1993 WRX on that chip untill december this year and covered about 8000 miles, never missed a beat and that was with pleanty of hard driving. In decemeber I bought a map from Anudy to cater for 440cc injectors and a FMIC, again since I fitted these with Andy's map the car has gone like a bullet - so far not a hint of reliability problems and very low knock activity, only problem is my standard clutch has pretty much died on my with the new map!
What sort of power gain did you see with the first chip, mate? (presume you had a decat also, anything else?). I have '95 WRX (260ps) with full Magnex decat and am wanting to know what the gain would be. Otherwise it's standard and apparently healthy.
Also, what are you clutch symptoms? My 119k mile (I think!) clutch seemed a bit 'soft' during launches at a sprint last year, but perfect in normal driving, no slip at gearchanges for example.

Oops, posted with my old login originally, apologies webby, it won't happen again, cookies didn't delete when I logged out after creating the new account 
(Its Andy from ESL).
Just to make this absolutely clear as I'm still not sure it is:
You are not getting the same product at a cheaper price. It is an entirely different board (ours uses surface mount components and is flow soldered) and, most importantly, a different map on the board, meaning different AFRs, ignition advance, boost profiles, etc. Ironically you are getting our board at £145 ex VAT and postage, but as we are a VAT registered engineering consultancy, we have to charge it.
Hijacking GBs aside, it is one thing for someone to copy an existing board design and have a generic map to distribute, quite another to have designed and produced your own board, written your own disassembler, decoded all the pre 96 control circuits in order to understand fully how they work as well as have all the relevant data locations. The person that best understands how the JECs operates is the person that is in the best position to map it.
Sizer, 272 quoted was at the wheels, read on a few more words and you will see that it equates to 340-350 hp at the flywheel, which is what you are talking about. It isn't possible without an uprated MAF, injectors, MAP and fuel pump. It is possible if you have the above, the data is rescaled to suit, you up the fuel cut and run about 1.4-1.5bar (application dependant). At that level it can get expensive though, standard rods internals will be on the limit, and the standard transmission is unlikely to do high mileage.
With postal maps older cars occasionally experience boost control issues due to numerous issues, including sticky (or disconnected) boost solenoids, lack of pipe restrictors, play in the actuator arm, sensors out of cal, etc, etc, and while it is possible to tweak the map by post, without actually seeing the car in question as a tuner you are in the dark. People often mistake chronic misfire for a fuel cut at higher boost levels which can be cured by new, correctly gapped plugs, coilpacks and (worst case) ignition amplifier.
For these reasons we believe the future of classic Impreza tuning does not ultimately lie with the generic postal map, although it will remain an inexpensive option for those that don't wish to go beyond a decat and filter.
To that end, ESL have developed a live mapping board with logging facility for imminent release through a geographically distributed tuner network, which is no mean feat when you consider the multiplexed nature of the motherboards expansion port and the fact you can map with the engine running. There are plans afoot for existing ESL customers to have a preferential rate on the new hardware (you would benefit from one of these at your level Will, contact me off snet).
Best of luck with the GB.
Cheers

Oh, I see.....anyway I think your chips are good. And I need another one but cant afford it because I lost my job! I'd recommend yours anytime, its still in my old WRX and does work very well (bar the fuel cut) but thats not a fault with the chip or map as far as I know.
My neighbour who bought it was told to get a Fuel cut defender then told that a dawes device would be better to limit the boost so think he is getting one of them and should run spot on.

I though you were self employed chap? Those stickers have survived the winter well btw, great job! Anyone after decals need go no further than Sizer. If you are still in the biz I might be able to sort you out another board if you can sticker up the drift car later in the year .
Tell the neighbour to contact me direct, he won't need an FCD and only needs a dawes if he wants to go over 1.1bar without ordering a modified chipset.
