theczechone Posted February 17, 2015 Share Posted February 17, 2015 So, I bought my swap from a member on here (wizardblack) and it came with V500 ecu. I am a total noob to tuning and as I am approaching first fire, I could appreciate some advice. I downloaded the base maps from wolf's website, but it seems to be limited in data. Do I just need to take the car to a professional to get it tuned or am I capable of doing it myself? I am pretty comfortable in programming so I think it would be similar. Is there some good reading anyone can suggest? The engine: RB25det S2 - Stock Coils - Evo 8 fuel injectors (440# I think) - Walboro 255 fuel pump - Aeromotive FPR - Stock internals - Pro Mod turbo by PureTurbos - No MAF, intending to use Wolf's internal MAP sensor - Freddy Intake w/ Q45 throttle body Target: 300-325HP, but right now I just want it to run reliably. Thanks for any help. Quote Link to comment Share on other sites More sharing options...
mtnickel Posted February 17, 2015 Share Posted February 17, 2015 Do you have a wideband o2 sensor installed? That will be the most important tool for tuning. An EGT gauge is also useful. More than likely you will need to have it professionally tuned. If you want to learn and are motivated, you could do a small amount of tuning yourself. I'd recommend to leave the wastegate lever completely open and perhaps only tune the vacuum portion of the map. I would 1) use the startup map they've given. You will need to use their tools in the software to calibrate for your injectors. Also will need to calibrate the injector opening time as well. Be sure to note as well if the ECU is compatible with low impedance injectors in case you are using them, and whether or not you need to add resistors. 2) Once running, I would imagine there is a scaling tool to move the whole map around. I would adjust the whole map (or scaling tool) so that it idles at the correct AFR. 3) Then you could begin to just get the Air fuel ratio's close. Hopefully there is a logging function where you can do some low throttle work and log the AFR's. Then make changes to the map and try again. You will very likely need a tuner however to 1) tune the boost portion of the map and 2) tune all the ignition timing. It's quite difficult doing the ignition timing unless you are experienced. You need to monitor for knock, tune for maximum torque in the off boost portion (for best economy etc). Possibly adjust timing around idle areas to insure steady idle, etc. Also, these engines can misfire a fair bit on stock coils. Will need to have someone around to know what that sounds like/acts like, as well as how to remedy (perhaps replacement coils, gap down plugs, colder plugs, etc). While you may like programming, an engine is a system of moving parts that need to be fine tuned. There is no control-alt-delete in one and incorrect 'code' (tuning maps) can result in a blown engine. As a youngster (teen), i went through 2-3 honda engines with my pathetic attempt at "tuning". Things that plagued me: - Assuming a basemap I had been given had "conservative" timing...incorrect, cracked ringlands, - Not monitoring/noticing boost creep/spikes...poor mapping in those unused areas led to a lean condition and again, blown engine. Good luck with the new powertrain! I too am an RB Z owner. Mark Quote Link to comment Share on other sites More sharing options...
theczechone Posted February 17, 2015 Author Share Posted February 17, 2015 A wideband is something I am still missing but will be getting really soon, actually bidding on one on ebay right now. But I will definitely have it before starting the engine What is the benefit of knowing the EGT? I'm definitely motivated and would rather do it myself for the sake of it, you definitely bring up some good points and the last thing I want to do is blow up the engine. The map shown in the ECU is 3D based of load, rpm, injection pulse. What establishes the load? Thank you for the advice. I'll update how it's going Quote Link to comment Share on other sites More sharing options...
ihavearustedz Posted February 18, 2015 Share Posted February 18, 2015 I too use the wolf v500, but on my l28. Ive been running it for almost 2 years. I still cannot figure it out completely. Try the wolf subforums here, I had a lot of help from a few members here. Also you could try posting on wolf forums http://www.wolfmotorsport.com.au/forum/ Ive yet to find someone near me that has experience using the wolf v500.
