Just bought a 96 STI RA V-Limited with an EJ25 short block, Stock RA heads and intake/turbo setup, aftermarket headers and up pipe cat back prodrive exhaust.

Needs tuning, but having only had experience with Tec3 and Autronic (out of price range) on VW's I'm now looking for the best option for a good tune, where later adjustments can be made on the fly. I havent used any of the ones i am asking about so i'm looking for feedback on each and can they be modified by user after initial tune.

Not looking for anything except best road performance and a little something something when needed lol....

IE: Can any of these run multiple maps for different driving? for instance a map for day to driving, lower boost better fuel economy use..... and say a day out in the country map for hold on to knickers hun i'ma putting me foot down or im on the start line at a track day, to the lights are red, im staged and set to go, 5 4 3 2 1 vrooom 1320 to go....

thanks folks

Speak to Jollygreenmonster (JollyGreenMonster.co.uk) as he can map all 3

How much you want to spend?

fygtbug

money im not worried about, but i would like to keep it under a £1000 for everything for now. atleast until i decided how far i want to take it.

which is why i am interested in the esl but i cant find anything that says if i can access with my laptop to make changes

currently have a gems ecu for sale off a my99, only 12mths. old...big saving to be had over new cost

fygtbug

got your pm.... thanks

looking for advice on each for now till i decide

I've had good experience with the ESL postal map on mine, but obviously you're refering to the live mapping solution that they now offer. If it helps, I've found the company to have great after sales support, and I'll definately be upgrading with their live mapping solution when I add a FMI, bigger injectors, etc.

ESL system is the one to go for - it retains all the factory knock control but still allows for significant performance gains

there is also the hydra (I think its called that) you can I believe get the software with that that will allow you to make changes. Also can have anti lag as well. Sure there is a thread in 3rd party about it at the moment.

with the powerfc you would need to get hold of the software and a cable (think the software is expensive)

ESL is gaining in popularity but I dont know if you can get the software to do changes yourself etc

bowsaaa

See here mate, SimTek seem to be the way forward.

ESL custom mapping is the most cost effective and also retains full active knock control. Apexi Power FC is more expensive but would give you the option of 4 boost levels to run, also the opportunity to tweek the map yourself via the hand commander.
For anything under 400bhp I would go with the ESL custom mapping of the original ECU, there are also a number of upgrades in the pipeline such as anti lag and launch control which will make it a tad more interesting

Andy,

ESL will love you for mentioning that.........everyones gonna want that feature now (bloody gimmicks)....LOL !!!!

Andy.F

Got to keep the pressure on him Scott Come on Andy, is it ready yet

Andy Stevens

Haha! Alright which do you want first, launch control that will instantly cause your TY752 to explode in a shower of cogs or coverage of MY97/8?

Spence has prototyped launch control but surely the scoob is one of the few cars that it will be of marginal benefit? Do you have it on the drag car Andy?

Scott.T@PolarPerformance

97/98 please...

Andy.F

Yes having the 97/98 OE ECU live mappable would be the priority for sure.

I don't use launch control or anti lag on the drag car. Its mainly a request for switchable anti-lag 'style' pops and bangs on the overrun that I get, not actual anti-lag which would be very hard on turbos/headers etc.
It is achievable to an extent on the Apexi but it would be nice to have it switchable on the OE

Andy Stevens

97/8 it is then, Spence is well into the design, I just need to get some prototypes manufactured and buy a car or two for testing, and expand the application software to suit. Address and Data aren't multiplexed so it is an easier task than pre 97. Thorough testing is the most time consuming aspect, but first half of 2008 should see it on general release.

I think LC and ALS are marketing devices rather than engineers tools IMHO. The fact that Andy will no doubt get into the 8s without them should say alot. I do alot of sprint/speed events, none of the competitive Subarus use it but they are capable of FTD (even in the dry vs single seaters on occasion).

If you can't launch a Subaru without LC then someone should take the keys off you! When we were testing with it, you had a completely open throttle plate and positive boost whilst stationary. You can imagine the horrible things it was doing to the gearbox when the clutch came up, especially a 15 year old 752.

To be effective and actually reduce lag, true ALS systems will take their toll on components in a way that may not be acceptable on a road car. Alternatives like clutch-switched lowered engine speed limiters allow for flat shifting, an open throttle plate and an unstalled compressor wheel will reduce lag but may still send a shock through the tranny.

If pops and bangs on the overrun are what people want then they can be mapped in via fuel and ignition tables same as you would on any other ECU. To make them switchable is again possible but not a current feature as to my mind its alot of effort for little gain (apart from annoying the neighbours and blowing out the exhaust baffles).

I've never been sure about switchable maps as if you get it mapped to optimum tune, why would you want to turn it down? Thats what your right foot is for. Imagine the expense of having it mapped multiple times!

I believe features like CLKC are useful on a road car given the variability of knock count with the SUL available to me. As is 3D boost control and diagnostic control codes, etc.

The board has configurable auxiliary IO ports on board so could be made to switch waterspray/injection on with Inlet temps/boost/throttle position as an example or have any sensor activate any actuator. It isnt offered in software yet (I have been trying to keep the sw design neat and simple, doh), but the hardware supports it and it would be configurable through the select port, so the hardware is future-proof.

All the above IMHO of course, I realise that we all have different priorities for our cars. Descending the soap box now. Donning fire retardant clothing.

pop and bangs are easy

Looks a great development path Andy

Andy Stevens

Hi Dunc. Its ok, but we hit a bit of a wall after 98, the OEM ECUs are already reflashable! Could always move onto Datsuns I suppose, the drifty crowd seem to like them

98 then Datsuns!!! yes please!!

fygtbug

OK this is my issue, bought the car, love the car runs like a dream, but needs work.....

ECU is part of it, also needs to have the fuel system done.

These are the current dyno charts






As you can see 3 main issues,
1 is fuel motor is just a tad lean lol at 4000rpm under load. after that she levels off to 12.2/3 or so.
2 is boost, 1 bar peak and then drops off to .8 pretty quick

3 is I know what needs to be done to fix and clean up...... I just dont know scoobies.... give me a VW VR6 or a 1.8T and im at home..... Scoobies scare me lol...

Sorry guys.... New to these cars, loving em so far, now just wanna get this one where it can be....

AlexJReid

Very interesting. I'd always planned on the PFC.
I'll definitely be in the (sizeable no doubt) queue for the MY97> when its released.

Andy Stevens

Queue starts here!

You look to be too lean fygtbug.

Good call MY97/98 is needed.
