just want to know what the base map is on my MINES ecu e.g what mods is it mapped for?! and what will it run good with without needing a remap?

What year is the car?

most of the mines ecus are 93~96 or 97~98..

the 93~96 ecu is mappable via the spare chip slot.. the mines ecu chip goes into that slot and a resistor is cut to change control to the new chip / map.
97~98 is mapped in a similar way
Mines is a Japanese tuning company (great naming a company after a bomb).

The actual mines ecu regardless of year is not mappable by normal means.. the eeprom can be reprogrammed but I am not aware of anyone willing to do that, there are far better ways to map a car, doing it live or at least programming it without the need to remove the chip and put it in a programmer and refit it etc sees much better results.

The mines ecu is usually running very advanced timing and needs reasonably high octane fuel.. at least 99ron plus booster.. although I have seen cars still detonating on that, and however I have seen the odd one perfectly happy.

Better to save up and replace it with a mappable ecu.

I'm watching a V5 ECU (off a classic WRX wagon) and it's going for £30+£7 del. Bargain!! Purchase that and get an ESL remap. Job done!!

Here's the link... Subaru Impreza TURBO WRX V5 ECU on eBay (end time 19-Dec-09 13:28:31 GMT)

the esl remap is a daughterboard that goes in the original ecu.. you can do that on your standard ecu.. it will save you no money as the mines chip will need to be removed and the daughterboard added..

however it is very good price for an ecu if you are happy to run 99ron +booster

yeah mate i do run v-power (99) and octane booster. but i just want to know will it be running nicely with my current parts (decat, induction, td05) and how will it run if i put front mount and 440 injectors?!?

scoobiewrx555

Put 440's on it and it will run really rich due to overfuelling bigtime. Some classics seem to run OK on 440's and the ECU seem to cope and deal with the difference until it's mapped. Others can run like a bag of ****e and you have to get it mapped or go back to 380's because it runs so badly. You might not think there is a huge difference between 380-440 but in real terms that's a stack of fuel going in over std.

Saying that on your mines chip it might make the car a bit safer on the one hand and lessen the chances of det due to very advanced timing, equally though this over fuelling can cause serious borewash. You're dammed if you do and dammed if you don't

As for a front mount...go for it. Cooler charge temps lessens the risk again of detting, and it will flow a lot more air than the std setup so that alone should lean AFR's out a wee bit too and that will be good if you go for the 440's reducing the impact of so much overfuelling.

If you make the changes your best option will be the ESL solution....in fact it's your best solution whatever you do on a V1-V2 classic.

IMHO get rid of the mines

Pavlo

The early ECU will NOT run really rich on 440s, if the lambda sensor is working properly, as the early ECU has a very direct overall fuel correction based on idle and light load lambda correction. But it will still be better to map the car for the new injectors.

scoobiewrx555

I mapped a V2 some weeks back that had swapped to 440's, front mount, full decat, etc etc... It not only ran rought but very rich too. Once injector scaling was corrected it was a different car, and then i could get on with the job of remapping.

Like i said, some cope and some don't. It's different for every car.

boss_man

really confusin me now... think i will stick with the car as it is, then later along the lines i will put in the 440's front mount then get an esl

Pavlo

440s, FMIC and an ESL board makes for a nice upgrade for not too much money.

boss_man

true! but what mods can my current mines ecu handle?!?!

scoobiewrx555

With Subaru's there are very few if any engine bay mods you can get away with not mapping for, but everything you mod can and should be mapped for as it all makes a difference.

I know little about Mines ECU's so not really sure of it's outright capability but as has already been said it's unlikely ayone in the UK will touch it, and my understanding has always been that it can only be mapped properly by Mines themselves so that means posting the ECU off to Mines Japan with a list of mods that you've done. Even then, and no disrespect to mines, it will never be a full custom remap until all the fine tuning has been done on the road to properly reflect the full capability of your mods with the safety of your engine in mind. Pavlo knows what he's talking about, don't know if he has any experience with Mines.

IMHO if budget is a big problem then just keep running it on 99RON and Octane Booster as has been advised, and without further engine mods. In reality unless you're going to spend some money on an option that gives you optimum control, scaleability and flexibility you're stuck.

If you wanted to keep the (non-mappable) Mines, I'd stick to no more than a decat d/p, full system, performance panel filter, PFR7B plugs and Walbro 255 fuel pump (the last 2 items will add a bit of safety). I wouldn't run a FMIC with it - as said, the Mines makes the engine run lean anyway. Whatever you do always stick to V-Power + OB and then check those AFRs on a rolling road after fitting any/all of the above.

Oh, and defo refrain from lengthy 4th/5th WOT speed runs on the Mines! IMO

how much bhp shud i expect with a mines and full decat, induction, td05, iridiums, walbro, runnin 1.1 bar?!? also i have removed my dumpvalve, blocked and it all up is this ok?!? the chatter noise now comes from the air filter

joz8968

Around 280bhp I'd say - normal for the ubiquitous 1.1bar + decat. It may make up to c.300 seeing as it runs aggressive ign. adv.!

TD turbos are fine to run DVless.

boss_man

is ok to leave everything blocked up?!? what difference would it make with a dumpvalve on?! or a recirc?!
