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!

 

apexi power fc. ,simtech, motec, hydra ....the list goes on

 

Running a Haltech here on my classic with antilag etc. Very good, no problems as yet, touch wood

 

Since you've already junked your MAF i wouldn't chuck money at trying to source another. This would therefore reduce you market to a speed density system like the Simtek or later ESL. Budget is a big factor as well, you won't get much change out of £1000 for a SimTek including mapping unless you can do it yourself, which personally i'd recommend

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!!!!!!)

Worth also considering Solaris - fantastic spec and complete flexibility over how it is set up. It has active per cylinder knock control unlike most other systems too which is a great safety net.

 

how much for supply only simtek apalmer?

anybody know if you can get software for fcon?

 

Hi Mate, i believe that supply only would be around the £700 mark, best to speak direct with steve simpson, PM is Steve Rally on the forum. But consider at this price you could also go down the Link G4 route, which is a great ECU for the money, software is free and i think it comes with the bells and whistles for the initial outlay. As for your FCon, its just a fuel computer, your ignition values are controlled by the Prova ECU and you would need to manipulate both.

 

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!

 

yes joz 93 wrx.......spoke to Steve Simpson and looks like I will go down the simtek route but there is no supply only. Who supplies the mafless esl?

 

I'll second that!

 

PM/email dynamix (who posted # 5 above) or JGM...

 

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

 

EA are in Witham about 13miles down the road, heading towards Braintree.

My mate said they had gone bust ... or have they indeed moved to Chelmsford, or something?

 

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?

 

check firt LinkEcu, this have launch control, antilag, autotune and you dont need MAF. this is PnP ecu.

 

how much and where from?

 

they have site Link Engine Management Systems - plug-in & wire-in aftermarket ECU's .

 

been there but they're in oz and theres no prices. Think im gonna buy a pfc but ill probably regret it!

 

The power fc is a very capable ecu, if can be mapped using a laptop if you have the lead and the datalogit software.

Banny

 

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

 

You cannot start the engine on the original ecu, if the maf is faulty. If you can source a maf sim you can run maf less with the apexi ecu.

Banny

 

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

 

thanks Banny, do you know how much datalogit and lead are?

 

Around £200 iirc but you may pick one up 2nd hand for half the price

Banny

 

well just won a brand new pfc with commander for 490 so anyone got datalogit software for sale?
