yeah I think thats part of owning a Subaru lol

not sure on that one to be honest ,, I had to swap my map sensor to get the boost up to 1.75 so that might be the limit but like I said I really don't know on that one and would have to ask the mapper about it

Aftermarket ecu has far more safety features, as well as better control over everything , but if not setup then just as useless as the stock one when the fan gets poopy

All the shutoffs are a must if your interested in minimising the damage done when things go wrong,

you can fit knock gauges i suppose but id much rather rely on the ecu to deal with that,

Proper wideband fuelling too list goes on and on,

Able to reference all sensors in map so can use EGT to control timing avoid melting things,

Only reason not to use one is budget tbh,

as I said I'm not saying its not a better ecu as I'm not stupid and have owned enough of them already lol but its a massive expense just to feel safe when my gauges do that for me,,, if your that worried about your engine going bang then find a better builder/tuner would be my advice as I couldn't drive around worrying all the time as it takes the fun out of owning them lol ,, mine get used hard and hasn't missed a beat yet so can't see how a ecu would benefit me at the moment

maybe of some use to you but have just removed from my blob spec c a tigwerks twinscroll manifold and twinscroll upipe. a md321t+ turbo ceramic coated and also a brand new k and n cone filter.would just need a downpipe to fit yours i think. rated at 480bhp. the turbos at turbo dynamics being checked out and will come with a full report on health.its done 3500 miles. was top laggy on a 2.0 litre for me.gone vf36 std.

looking for 1700 turbo with all the fittings
300 manifold and upipe. beautifull piece of kit.
150 incuction pipe with maf housing in alloy and very large k and n which is brand new

it would be an animal on a 2.5 but you would need a new dump pipe i think ..

md321t+ twin scroll as removed

im sure it would be great BUT i couldnt live without the burble buddy

no worries

I agree with you about people can get it wrong as we are all human but the ecu won't stop things going wrong if there not done right in the first place , it willl just tell you its starting to go wrong in hope that its nothing major lol but by that time its prob to late anyway lol

so just because the ecu doesn't have 1000 safety features its now the gypsy way of mapping lmao ,,,, seen these ecu's running well over 600hp without any problems for many years now so can't see why it would be a problem for me now ,,, and have seen the most expensive ecu's in scoobs and they still went bang lol ,,, and being my daily road car if I do get a problem I can do a fault code read and fix it ,,, instead of having to go to a mapper and have them do it and try and find the fault

I like how its implied I'm a cheap skate but iv prob spent more on Subaru parts than most people buy there whole car for so its not about money for me as my cars get whatever they need ,, its about what works best for me long term and spending a fortune on a ecu that isn't going to change anything on the car seems a bit of a unneeded expense (at the moment) when its working just fine and my gauges tell me enough not to worry

if bob wants to sell me a ecu (and make a few quid of me for a change lol) then ill happily buy one but until he tells me its NEEDED and my current ecu isn't safe I'm happy to use it

ill be adding flex fuel set up to the system soon so will be even more power lol lets hope my ecu can take it lol

we are all getting off topic though as it was a turbo thread lol

long live the FORCED PERFORMANCE RED (well my one anyway lol) ,,, turbo from the states so iv prob brought that to be a cheap skate aswell lol

read the spec lol

if it came across that i was saying you were a cheapskate then i apologise as thats not how i meant it to be, i am genuinely interested as im having a big build myself next year so gathering as much info as possible.

wasn't directed at anyone really but was said above that some people try doing everything on the cheap lol ,,, I might not want to spend a fortune on a ecu for my road car but that doesn't mean I'm a cheap skate as ill happily spend money where needed but plenty of Subarus out there running bigger spec than me on the original ecu

my opinion is just my opinion mate but ill happily give it if it helps you make the right choices for what you want as its you that matters at the end of the build,,, been doing it a while now and haven't had any major issues for years and years now but have blown enough £10k builds up to know what works for me lol

1000bhp to run a 9 lol

Must be the stock ecu holding it back hahah

Its far easier to play around with a stock ecu than do a fresh install with a aftermarket ecu, so as far as bob (or any other tuner) making money he can squeeze more reflashes of stock ecu in on one day than fit aftermarket ecu so its not really an earner and more labour intensive,

Do you run any sort of knock sensor or gauge ? (knocklink)

Would you have a visual eth content gauge for flex fuel ?

All these things the aftermarket ecu have far superior control over and eventually when you add up the cost of all gauges its not cheap either for something which does nothing really.

Saying cars with well over 600bhp last years is only true if they do very few miles actually using their 600bhp, lets not kid ourselves, rod bearings & other expensive stuff becomes serviceable,

Also without the top ecu surely power is left on table as it doesn't have same safety margin so worth it for that alone to maximise the builds potential,

so gauges now do nothing lmao

not everyone pays the same to have there cars mapped I can assure you of that lol ,,and bob makes very little from me (if any at times) with regard to mapping my cars so trying to say he is squeezing more money out of me just isn't true ,,, he would stand to make more from selling me a aftermarket one but until its needed I'm fine without it ,,, I'm not saying there wouldn't be benefits but for me they are not worth the extra cost at the moment when the standard ecu is working fine and my car is proof of that

iv done nearly 25k miles in 4 years @ 530 so not massive miles but no sign of anything failing yet and I drive it hard quite a lot and use my launch control every now and again so don't baby it around and can't see why I wouldn't get another 25k easy enough

Nobody says he was squeezing extra money from you,

"if bob wants to sell me a ecu (and make a few quid of me for a change lol"

Just pointing out that installing & setting up a standalone is a different kettle of fish from reflashing a stock ecu,

Alot less cash for work done,

So obv wont be pushing the aftermarket ones as no incentive,

And yes unless gauges are wired into the ecu for it to read data and adjust to get most out any situation, they do nothing,

Fuel pump failure for example you can say bye bye engine,

lol so your car blows up soon as you run out of fuel lol ,, must be well built then ,,, iv had fuel pumps fail on track days without my engine going bang so that makes no sense at all ,,, iv also had a oil pump fail and was saved by my gauges tell me ,,, might still have the pic somewhere of when I pulled the pump off and found the bolts coming out of the back ,I only noticed due to the gauges , so can't see how they do nothing when they saved me a forged engine after my oil pump failed (this is fact that has actually happened to me not what iv been told)

read my posts properly then as I clearly say there would be benefits but they don't seem worth it to me at the moment

so buying a second hand turbo is wrong why ?? , knew the history and was low miles that had only been used to 1 bar so why spend money thats not needed ???

standard clutch has been fine till recently so why would I change it when its not failing ?????? ,, ,exedy twin plate waiting to go in so why would I create more work for myself than needed ????

your wrong about bob ,, fact is iv had plenty of work done by him for nothing and most of my recent mapping has been sorted without any cash changing hands ,,, so say what you like I know what the facts are and he has mapped 100s of mine and my friends cars without any problems

if your trying to make out I don't like spending money then try again as the parts in my attic for my main build are prob worth more than most peoples whole cars ,, and most people wouldn't even consider buying them

Which part do u not understand ?

Goes lean and usually dies quite common if you have a look.

or does your engine builder perform magic tricks when building so this cant happen.....

nothing to do with who you use.

just common sense.

Id much rather my expensive engine wasnt running with low oil pressure no doubt shells will remember that day.

proper ecu cuts it as soon as sensed so any damage is kept to a min.

If doing a budget build then fair enough but i wouldnt be under any illusions that it wasnt necessary.

bit like me saying forging isnt necessary coz my car is at 487bhp and not died yet.....

well my fuel pressure gauge would tell me there is a problem if it was failing wouldn't it lol ,, then id just turn the key and stop the engine ,, you keep saying about budget like its a problem for me ,, iv got parts for my builds that are worth more than most peoples whole cars so I'm not worried about spending money ,,, try buying WRC or gobstopper parts and then speak to me about budget as most people wouldn't spend the sort of money I have on parts lol

why not trade some of those gucci parts for a more common mod then like an aftermarket ecu then ?

must be difficult to drive with eyes going all over place like a chameleon too, rather focus on driving.

I guess if moneys no object like you say then nothing to lose just a bigger bill when it goes wrong, but to say that then miss out on just how much better the car would be with one seems odd...

because I believe its not needed at this stage and my other parts are for my main track build and not my road car as that is what this is

so tell me with all your wisdom and experience with big builds how much better would my car be ?? as like I said it drives just fine on and off boost and i don't need eyes all over the place as iv got alarms set to flash and bleep if I get a problem , if I chose to ignore them then I deserve to have a blown engine really

as iv said already many times I'm not saying there wouldn't be benefits to fitting one but for me the extra cost doesn't warrant it at the moment as the current one is working just fine

im not going to clutter this thread up any more with us bickering so I'm happy to discuss it via pm if you still want to go over the pros and cons as I'm happy to carry on discussing like adults without arguing over it lol

I understand and shouldn't let myself get drawn into this crap on here as its what spoils the place

first page was a fine as I was only asked my opinion and gave it,. but then I became the cheap skate anti-christ due to not running a aftermarket ecu on my hatchback lol

The only reason i even commented was when your that with failures once its going its gone so ecu pointless and that if you have gauges then you can do a similar job to an ecu which just isn't true,

If you honestly need me to tell you how much better the car would run & perform then you obviously haven't looked into it much......

Nobody says your a cheapskate, or that your car runs poor at the moment, just that it would be better as well as safer.

I'm sure most of the parts you removed from the car would have worked fine just like the ecu :)

you lost me now ,, what parts are you on about I removed ?

Meaning upgrades :facepalm:
