which ecu?
Hi all. Want to change my ecu, currently have a prova ecu with hks fcon v piggyback which would be fine but you cant get the software to map. So what would be my best option? could I use an esl on my prova ecu?(early wrx) At the mo it runs without maf so would I need to put one back on? Missed an autronic pnp ecu last week on ebay, gutted!

There are many SD systems to be had, i can only comment on the SimTek/Power-FC as i have one of each for different cars. The Simtek is a well spec'd ecu and in the right hands will perform as well as any other mentioned. The apexi is not an option because they never made an SD system for the subaru, but similarly a very good ECU and arguably more than adequate in the right hands. (If you managed to pick up a MAF however the Power-FC would be an option, although last time i checked they were well over a $1000 new!!!!!!)

Actully it turns out that the Fcon Pro V does control timing. I would contact HKS and enquire about the software. You'll probably find it has a predetermined limit as to how much ignition and fuelling it can provide above the std ECU as well so this may be a limiting factor. Interested to here how you get on with that

jimes, I take it when you say "early WRX" you mean a MY93-96 one?
If so, then for me, the latest MAFless ESL LIve would be best. Ticks all main boxes IMHO:-
Price
Will be cheap(ish) (the original MAF-based one is £550 +VAT fitted and mapped), so it'll be a similar all-in price, I would have thought.
MAFless
THE major engine sensor... that you now won't have to fret about failing (and possiblty knackering the motor).
Active knock control
Still retains/reads all of Subaru's (excellent) I/O sensors. This includes the in-built IAM ign. ret./adv. feature, which actively helps to optimise performance and, if required, will retard the ign., posssibly saving your motor!

I have a HKS Fcon pro V on my car.
You dont have to just have them as a piggyback ecu, mine is a stand alone ecu.
They are actually a very good system that have launch control and anti lag on them.
Talk to engine advantages down at chelmsford about mapping it, they quoted me £250

my fcon is just the v not pro v and want to be able to map myself so thats going in the bin! Reall want to go with simtek as Steve Simpson seems a good bloke and willing to come to me but a grand (inc software) is a bit above my budget at mo! Seen a power fc for half that but would have to go back to maf which doesnt relly bother me as im only aiming for just over 300 and im told I can use a maf from nissan z32 which I have a whole one sat outside non runner! Just not heard much about the apexi, are they good? can you map from laptop or just commander?
ESL would have been ok but dont think you can self map?

Power FC is good, but you need to use MAF. If MAF not working then you cant even start the engine(with original ecu you can).
found seller from UK
Link - Thor Racing (Japanese Performance Car Tuning)
Rogue Systems - Link G3 LEM (Link)
Power Max Engineering - Bringing Your Engine To Life
probably you can get cheaper from manufacturer

i did run the engine when the MAF wasnt connected, even TMIC wasnt installed(original ecu). but one dude who MAF was faulty, didnt managed to start the engine(power fc). i dont mean that power fc is bad. i was thinking to buy it first(cheaper then link G3), but after i had spoked one tuner, i canged my mind. he said that best is system without MAF, less thing to worry
