Subaru remap herts

[vxr2010]

Firstly sorry for mentioning a non v8 car , but as above any one know who can remap a Subaru turbo in the herts and also costs if known please

I saw this when looking at 'whats new'. You would probably get a better response in the Subaru section.

Anyway dependent on the spec of your car could depend on the route chosen.

This site gives a good example of the ECU's and costs. Different tuners cost different amounts but the prices here are somewhere in the middle of the range.

I'd only recommend a tuner with a good reputation i.e. Duncan (who runs the above company, Alan Jeffrey's (Engine Tuner), Bob Rawle etc. Too many Impreza engines have been destroyed from poor mapping.

We could probably give you more info if you can give a bit more information about your car, aims etc.

Any of the above options would be fine...of course options also depend on exactly what model you have.

Lateral Performance are based in Watford and are highly regarded in the Subaru scene. Possibly worth giving Mark a call and asking who he'd use in the local area.

I've just had my Subaru engine mapped by RS Tuning in Leeds but that's obviously not too local.

Hi cheers for replies , car is a jdm sti version 7 , it's got forged internals and revs to 8200 which is pretty mad , I think it comes with around 285 to 300 bhp , it's got a k and n panel filter and it's only got one cat after the turbo , centre pipe is now a straight through and a sports back box , it also has headers which I believe are standard , it's not twin scroll , I think best route is just a remap ? Interesting to know what it can chuck out bhp wise

I think the JDM STi 7 has a VF30 and 565 injectors which is good news as it means it should be able to see somewhere over 330bhp as long as it can breath well enough and has a decent exhaust.

I'm running an Alcatek on my RB5 as it was recommended at the time. I wanted to go MAF'less as well as I was having issues fairly often with the MAF on my car. For the initial map, I had a K+N Filter, 3 port boost solenoid, better quality spark plugs (PFR6B), RCM fuel pump and some other minor changes. I also went with the AL + LC option on the Alcatek although I never use either.

Here is the turbo list; http://forums.nasioc.com/forums/showthread.php?t=1...

A quick google suggests lots of people have run around 400-450bhp on the standard internals although what a safe power level maybe a different matter and its worth taking advice from a good engine builder/mapper.

If it's more or less standard which it sounds, then yes a re-map would release a good bit more power.

Unless the engine has been rebuilt with forged internals, then they do not have forged internals ! They do have forged pistons, but the rods are still cast items, although a huge improvement over older versions and are quite robust so even around 400hp you should have no real concerns with any of the engine as long as it is in good health.

You could ask Mark @ Lateral, but he does just sell goodies.

If you look on the Ecutek dealer list there are a few local to you, that said I've never actually heard of a few of them.

Bob Rawle's reputation is solid and he is mobile so definitely worth a shout. Or you could give the guys at Torque Developments in Essex a shout. They arent too far away.

I've had several years of experience of Impreza's and mapping and here are my (unqualified) thoughts on the subject.

The view tends to be; Syveks (most advanced/capabale) > Alcatek (used to be called Simtek) > ECUtek > OpenSource. Although a good map can be created using any of the ECU's some of the more advanced have features that mean they can protect the engine better and can achieve the maximum from the engine. I went for the Alcatek because I like the fact it has advanced knock detection and correction. It also has individual cylinder Fuel & Ignition Trims etc. I have switchable maps in the car although its normal map is for 99 fuel.

There's a good thread on ECUtek on ScoobyNet and it contains many of the most respected mappers (Alan Jeffrey - EngineTuner, Andy F - Andy Forrester Performance, Jolly Green (R.I.P), Dynamix - Race Dynamix, Martyn J - Alan Jeffrey's son who does my car and Bob Rawle).

http://www.scoobynet.com/general-technical-10/8062... - If you can make it through these pages, there's a lot of good info in there.

Finally, I don't believe in only road mapping a car as I've had several problems with cars purely road mapped. I believe cars should be dyno mapped to start with as they can really drive the car hard for as long as it takes/as many times as it takes to get the map right before moving to the road and checking/tweaking the car on the road. This I believe is really important in optimizing the map(s). I know plenty of folk believe a road map alone is enough but I don't think many would argue that a combination of the two is advantageous.

A good map will transform the car!

Hi thanks for above replies a lot to digest and I will make some enquiries

I've had a lot more than several years.. but certainly at the level the OP is asking and on a standard car, aftermarket ecu's aren't really needed. Depends whether it's a quick hit he wants or something to build on for the future...and of course how much he wants to spend

Whilst the hardware is a very important part....the person using that hardware is even more important. I've seen many many re-mapped Subarus drive like st because of poor mapping. Hence go with one of the above named people who have solid reputations.

As for the dyno vs rolling road argument. A rolling road will never simulate real world conditions, so whilst a very useful tool, even a car mapped on rollers should be finalised on the road.

But plenty of guys out there are tuning cars on the roads/tracks and producing outstanding results, often better than those mapped solely on rollers. But again, a lot of that comes back to the person doing it, not anything to do with rollers vs road.

And for what sounds like a standard/common car, having it mapped on rollers...really is an added expense that will not yield any benefits.
