Hi. To reply to the past 3 questions: RSlegy - Yes, once we have set the ECU up to be fully tunable we do have the ability to remove the AFM and tune on just the MAP sensor. However, this will take a little bit more time on the dyno to set up correctly. Karl Fxcking - Between the ECU setup and dyno tune most of our V1-4 tunes are working out to be around $1450. reaperblitz - Yes we could do this, but we have no faith in mail order tuning especially on modified cars and if there is nobody checking the end result afterwards. If you have a local tuning shop that we could work with to check the tune afterwards and give us feedback on any changes required then we could consider it. We have now made up a bench test harness for the V3/4 ECUs so we do have the ability to power them up, test them and make tuning adjustments without having the car. However, if we just start raising boost limits etc and sending off ECUs to hope for the best then we become no better than the morons selling mail order chips on TradeMe. The better long term solution would be to get a couple of the major North Island tuning shops set up to tune these ECUs after we had converted them into a tunable state. But we aren\'t quite ready for that at this stage.

Hi Nick. There is a possibility of 98-01 BE/BH Legacy support in the future. We can already retune the 01-03 BE/BH facelifted models.

Hi Guys. We thought we would just give a bit of feedback now that we\'ve retuned several V1-4 WRX and STI cars on the factory ECU. First of all, the bad part - setting these ECUs up to make them tunable is quite difficult especially on the V3-4 GC8 cars. Additionally the parts required to do this are a lot more expensive than on most of the other cars that we offer factory ECU retuning for. So these are the two reasons that the initial set up cost is high. Unfortunately, we\'ve been forced to increase our price on the ECU setup part of the job to $900 as we were actually loosing money on the ECU setup on the jobs we\'ve done so far. Even at this price it isn\'t particularly profitable for us. However, considering you end up getting a fully programmable plug-in ECU with closed loop boost control, closed loop knock control and the starting point for the tune is your factory Subaru tune, we still feel that this offers good value for money compared to the other options. The factory ECU makes the Apexi Power FC look pretty average. We still prefer the Link G4 plug-in ECU as the ideal option especially for motorsport cars, but at $1943.50 (this doesn\'t include closed loop knock which adds another $818 for those that want the KnockBlock G4 as well) the price difference is significant and outside the budget of many. The good news is that these cars have been tuning up very well and the tuning process is quite efficient and straight forward. Tuning time has been quite short and we have been really happy with the results. On a lightly modified car (exhaust, intake, intercooler etc) with stock VF series turbo, yellow STi injectors etc the average dyno tune price is working out between $400-500 including dyno setup and removal. This is roughly half of what a typical retune costs on an aftermarket ECU. The time savings come from being able to just play with the areas where we are looking to make more power (i.e on boost) and leaving everything else like the light load mapping, acceleration enrichment, cold start, etc on the factory settings. However, we can tune higher powered setups with bigger turbos, injectors upgrades, AFM upgrades (or even MAFless). Some more good news for V5/6 owners is that we will soon be able to retune the factory ECUs on these cars too. Pricing hasn\'t been officially set, but the cost should be cheaper than doing a V1-4 ECU as these ECUs can be reflashed via the OBD2 port.

Hi whatchain. You are correct. We are charging a fixed price for the ECU setup, but the rest of the price is depended on the time we spend on the dyno doing the tune. Therefore, we are allowing a total of $1400 for a custom retune with injector, AFM and turbo upgrades. If your car has a stock injectors, AFM and turbo and you are just wanting us to optimize the tune to run this set up then this will require less dyno time and we would expect the total price to be in the $1000-$1100 range.

Hi guys. Thanks for the positive feedback. Regarding pricing, we are charging $600 to upgrade the ECU into a fully tunable state where we can log and tune in real time. The reason that these ECUs cost more to tune than the V7- is that the hardware that we use is relatively expensive and it takes time to install it. But on the plus side, once it is upgraded the V1-4 ECUs can be tuned in real time which is a big advantage over the late model cars. A custom dyno tune will be approx $400-500 for a car with stock injectors/AFM/and turbo or approx $800 for a car with injector and turbo upgrades etc. This assumes that the car is in good condition mechanically and electrically and doesn't have issues that we need to sort in order to do the tune. All of the factory ECU features can be retained. We understand that some of the North Island guys are feeling a bit left out, but we aren't comfortable with upgrading the ECUs for other people to tune just yet. Once we have tuned a lot more of them and have a bit of a map database and enough experience to give other people support, we will consider working with a North Island based tuning shop to bring this service to the the NI guys. Regarding V5-6 cars, these ECUs can be reflashed just like a V7-. However currently we don't have the the tools to be able to do this. The last time we priced buying the tools they were very expensive and we couldn't justify the cost. The price we would have needed to charge for a retune would have been getting too close to the cost of buying and setting up a Link G4 plug-in. If the price of the gear comes down in the future we would love to offer this service to V5-6 owners too.

Hello all. Firstly, thanks to aim for allowing us to mention this. For many years, NZEFI has been performing custom retuning using either aftermarket or factory engine management systems. We have offered factory ECU retuning solutions for the V7 and later WRXs & STIs for quite some time now. However, until recently, our only tuning options for the GC8 WRXs have been to replace the ECU with an aftermarket system like a Link G4 plug-in. This is a great solution and it is still our preferred one, but it is expensive and not affordable for everyone. However, we are proud to announce that we have recently purchased the equipment to tune V1-4 WRX and STI factory ECUs. We can now retune these factory ECUs for more boost, different fuel types, different turbos, injectors, AFMs etc just like the later model Subuarus. Better still, once we have upgraded some hardware in your ECU, we can tune it in real time while the engine is running - just like an aftermarket ECU. This speeds up the tuning process significantly compared to the normal reflash method used to tune the factory ECU on later model cars. Once your ECU has been upgraded, we can tune it as many times as you require quickly and easily. This service is available only from our Christchurch based workshop. Sorry, but we will not be offering mail order or generic tunes as we can't deliver the outstanding results that we are known for without you bringing your car to us for a custom tune on our 4WD dyno. The process will typically take two days to complete and your resulting tune will be specifically tailored to your car and your modifications. We guarantee you'll be satisfied with the results. We are looking forward to working with the GC8 community to get these classic WRXs running better than ever without breaking the bank. So if you are interested in this new service, then please give us a call on (03) 377-5447 or email [email protected]
