Defender Td5 90 Upgrade from Stage 1 to Stage 3

[@alivetuningltd]

Thank you, we really appreciate comments like this as it makes it all feel worthwhile. Vlogging our jobs takes significant extra time, especially so in the editing, so it’s encouraging to hear things like this. 👍

Stumbled across this channel whilst looking for a TD5 defender and checking KZbin for a buying guide. Really interesting stuff, I’m catching up on your back catalogue of videos, a great channel - thanks so much for sharing. Blimey, haven’t Defenders shot up in value. Been a while since I had a 300 TDI, and feel the need for another defender in my life. Now all I can think about is new turbo, exhaust and intercooler! Keep the videos coming, I’m really enjoying them.👍

Another great video 👍🏻🔥love the channel

Great video! Really good to see issues and tweaks you have to do shows just how different each td5 is. I guess at the age these are now these all have different wear etc. And custom mapping for each will really see the best out them. Interesting the EGT temps as well 750 must be the limit you'd want pre turbo? I noticed it must it didn't go of in the later tunes :) Lots of great things to learn here thank you!

750 degrees EGT is where most OEM’s set their limits in modern turbo diesels, that are fitted with DPF. In reality we can run a bit higher than this with the Td5, and we’ve seen some eye watering temps I can promise you! It’s true that as the Td5 ages, they all benefit from individual custom tuning to find each one’s sweet spot. Although not mentioned in this video, I can see on the dyno exactly what is holding this one back from making any more power than it does now, and it’s related to wear and ageing. We try to educate with our videos and it’s good to know that people are taking note. Gary.

@@alivetuningltd Thanks so much for taking the time to reply! And for another little nugget of info! :) I have a little hunch what's holding it back. So much great stuff out there on these but the live Dyno you really get to see what's going on and build up a picture if you pay enough attention. Its interesting to see variation on the Axel power across different trucks. Vlogging is very much appreciated. Fun to watch and lots to learn :)

[@alivetuningltd]

@@graemedenchthe transmission losses are an important factor in calculating bhp. The Dyno knows the mass of its own rotating components, and so can calculate the drag of the vehicles drivetrain on the coast down and apply the measured losses against the wheel hp figure from the pull. Correction factors are applied to approved standards (ISO, DIN etc) in conjunction with environmental data from our own weather station, to give us accurate power and torque measurements. If you think about the drivetrain on a Defender, and then consider how tyre size, pressure, tread pattern, tread depth, sidewall stiffness and even the rubber compound can affect the drag. Then there’s gear and diff oils, which become less viscous when warmed. Binding brakes can cause increased drag as well, of course. It’s a deep subject, but one that’s important to understand when reading our Dyno graphs.

I’m on a alive stage 1.. need the upgrade 😏

[@alivetuningltd]

Treat yourself to an Alive Power Flash, Andrew. Let’s give your stage 1 a long overdue update! It’s great to hear from you too! 👍

[@danlovelock778]

Id be interested to hear whats being changed inbetween map revisions.

Another great video, is there any benefit In blanking the egr?

[@alivetuningltd]

EGR is often misunderstood, as it serves many purposes on a modern engine, both diesel and petrol, and it is a very good thing. For the Td5, the EGR design isn’t great, and with ageing the EGR valve can easily unseat when exhaust gas pressure rises. This causes uncontrolled EGR and that’s really not a good thing, as it’ll add too much exhaust into the inlet manifold, diluting the otherwise, oxygen rich, air charge and subsequently causing sub optimal combustion. One of the many effects of this situation is that the exhaust gas will have much increased particulate matter and it’ll keep recirculating this back through the weak EGR valve, compounding the problem. A Td5 runs more efficiently without an EGR valve, there’s legal implications in doing so if the vehicle is to be driven on the road, where it’s homologated emissions standards dictate that EGR should be fitted. There’s loads about this subject online so have a read up on the pros and cons of EGR, then make up your own mind.

👍 Great channel, always good videos. Gary mapped my Auto 90 many years ago, before dyno days. Can you get an accurate dyno result from an auto??

[@alivetuningltd]

Hi Jerome, and thank you once again for the calendar we’ve received, for many years now! Autos, especially the ZF4 types, just won’t lock up until around 2500rpm and so we can only record real data from there on, and that’s usually way past peak torque. If you fancy a bit of a refresh to your Td5, I can promise you a trip over to Alive HQ will be well worth your while. Drop us an email if you’re interested. Best wishes to Donna and yourself, and we’ll hope to see you soon.

Another interesting video. Is it a good idea to be able to read the reg and all the codes with your new scanner?

[@alivetuningltd]

The in-depth access to control units that Power Flash gives, is no bad thing at all!

[@DrizzDevelopments]

What Operating Systems does the power flash work on? I only really want it as a live data system so will I just need the cable? Does it work on a 10p? Thanks

[@alivetuningltd]

Power Flash works off a Windows PC and it’ll work with both engine types. You’ll find much more about it on our website, www.alivetuning.com

[@DrizzDevelopments]

@@alivetuningltd Yeah I looked but couldnt find any details on what Operating Systems it works on. Im trying to find videos on its live data options as that all id want it for, not bothered about mapping etc

[@scaifefab4585]

Will rolling road take a 130 ?

[@alivetuningltd]

It’ll only take a 130 if we disconnect either the front or rear prop shaft and run it as 2 wheel drive.

[@graham-martin5847]

the intercooler would work even better if you mooved the reg plate away from the front of it lol

[@alivetuningltd]

We actually questioned that too, but even with the reg plate on the grille, intake air temps were still below 30 degrees at full chat!
