Gratitude Duncan for being a paragon, an absolute unit in the community, cheers mate.

Cheers Duncan, ive started data logging my forester, this series couldn't have come at a better time! ESC legend 👍

Keen to see your live tuning video! I'm always intrigued by how others approach ignition timing maps when tuning an EJ. Cheers!

You're a legend for this

thank you sir, cant wait for the next video. Lots of love from south africa

thank you sir. Please can you touch on IAT vs Timing compensation tables, post and after turbo.

Hello. I have an 04 wrx sti USDM. I cracked my ringlands on 2 cylinders one night driving hard, so I tore it down and am currently rebuilding it entirely. New forged shortblock with new heads. What it used to have was a FMIC kit, ported td06(deadbolt sz49 I think), uel headers, tgv deletes, side feed(not sure what cc) grim speed boost controller, hks bov and catless down pipe. I know it was tuned on an opensource software since there’s no access port or piggyback on the ecu. Currently, I am putting on DW1500cc injectors top feed, FP black, 19mm intake spacers, iwire Wideband o2 sensor, grimspeed up pipe with 40mm turbo smart ewg, iwire speed density hybrid kit, and a few more goodies. In addition to following keeping a copy of the original tune and lowering target boost, wastegate duty cycle set to 0 and retarding timing. Should I hold off on installing the speed density kit until I get my MAF scaled appropriately to the new injectors? I’m spending time here and there on romraider forums and it advises on not messing with speed density until you’re very familiar with maf scaling and the like. Also this is a new shortblock and I’m more scared than anything on having a terrible first start and breaking it in. Yet I want to learn how to tune the car so that I can fix and find problems while having fun. Sorry for the long comment. Cheers!

'What temperature should I set the oven to Mr Hollywood please?' another great video Duncan, even I was understanding it 🤣 I'm having to change my car so still no towbar ☹ I will get the gc8 to you one day.

Thanks for doing this Duncan; I would like to become a member and join you on your Tuning Academy videos/lessons.

Thanks Duncan once again. you have been quiet for a while!! You must of been mega busy in life glad your well and ok . will my AEM AFR gauge be accurate enough for tuning? Cheers grant Just another quick one could my old écu have been écu lab tuned? And Locked 👌🙏👍

Really enjoyed the vids so far, I have a UK Foz XT with PPP map (I believe this may or may not be locked) I want some Tutu noises and have a Perrin intake, they market these not needing a map, diameter wise looks the same as the MAF. Have you found these need mapping? From watching the previous videos it’s a resounding yes.

Can you do a video on the correct way to work with changing the DAM values so that it doesn't keep wanting to add timing to your tune? Perhaps even ways to use the DAM system to your advantage while tuning? I'm working on tuning my 2016 FA20 DIT engine.

These sound like pretty solid tips if you're running a turbocharged Subaru. I'd imagine that the process would be similar for a N/A engine. I have a '15 Impreza with the FB20, a Tactrix, and SubaruEdit. I've been mainly data logging to learn a bit about what the car is doing, but is there anything that you would do differently with a N/A engine other than maybe targeting a leaner AFR than 11.3:1?

Get a Full Duplex 4g sim EE is good. It connects to two channels at once. You get 30Mb up plenty fast for streaming !! Keep up the good Vids

Any mention of knocking? I really like your safebase map idea. Then keep pushing & them when errors show you know it's the most recent change & such. Cool man helped me thx

Hi duncan, will the innovate LM-1 work fine for me to learn with as iv come across 1 of a friend as he's upgraded??

i have slight feedback knock of low rpm 2800, doesn't matter what i do it don't go away. more fueling less timing always there, more so when the engine is still warming up, cant hear anything on the det cans. could this be noise from a forged engine?

Hi Duncan quick question I was running a map on my 2011 sti with stock turbo fmic, stock injectors and some bolt on mods,it was about 362 bhp. I've just upgraded tp td05 20g fuji top feed rails 750cc injectors ,340lh fuel pump and all supporting mods that go with it air pump delete tgv delete etc. Would it be OK once I tighten everything up to start it just to see that it runs with no leaks etc and then switch it off. 🙈🙉

how do you deal with bigger injectors, apart from scaling and dead times what other tables do you alter?

Do you have a tune map for a EZ30 R as well? as it's pretty hard to find a desent one Cheers mate

Hi Duncan, when mapping a car that doesn’t want to make power is there a step by step process you have to go through to help find the issue? I’m sure you must be pretty good now at knowing what the issue is straight away on Subarus, and what issue seems to pop up the most? thanks in advance

Do you have any similar advice for tuning an n/a Subaru motor? Specifically an EJ253 to be running explicitly on premium 91+ (US/Canada rating) Octane fuel? (stock everything, except lighter crank pulley, intake tract extended to pull from a bonnet CIA/dust snorkel and DIY free flowing catback) Probably an odd request, but we race RallyCross in Canada in N/A AWD class and the 10-15hp (or more?) we'd love to get would make all the difference to get a few fractions on race day. Found your channel recently, been enjoying it and learning a lot so far, but finding info on squeezing marginal gains out of non turbo Subarus on the net is a bit of a challenge!

What is a good software for a virtual dyno so we can see gains with road mapping ?

How do you get around an ECM that is erratic. My 2013 Subaru WRX STI ran great and made a lot of power until COVID-19 when a dome light was left on and it sat dead for 3 weeks since then I have retuned it multiple times and may run OK every now and then but usually erratic error codes stumbling and misfires. I plan on putting new plugs in and resetting ECM while battery is out and installing my best Cobb tune. It is frustrating. I have a replacement ECM but it is difficult cloning VIN and other info so the car will run. I can mail both ECM's and have the clone done for around 150$ but what happens if both get lost in mail.

I would love to do this but I still have not found a way to tune my 22 WRX as of yet. Since Cobb got pressured by the EPA nazis to stop allowing people to do their own tuning there seems to be nothing available for this new generation of Subarus. Do you happen to know of a solution?

hi, can anyone email me a tune please - car is a 2005 Legacy BP5 twinscroll, upgrades - version 9 STI scd shortblocked/forged pistons, RCM fuel pump, cosworth panel filter in the stock air box, full decat exhaust from turbo back, it is an Auto but has had the vf38 turbo removed and replaced with the larger td04 from the Legacy manual. Car is just a daily beater, it gets driven around fields and has takes dogs and kids to the beach, it dented and scratched - car is probably worth 1k total, so I dont want to spent 600 mapping as thats half what my car is worth lol - but if anyone has a map for a similar car they can send me that id buy that, thanks
