NRS91

No argument here, just a discussion :) I haven't written a How To for tuning on my website yet but I talk all my customers through install and tuning on a 1 to 1 basis and if they aren't feeling confident I do have a list of dealers who do installation and tuning too. Feel free to drop me a message via Facebook, website or the forum.

The customer likes to "roll coal" and the customer is always right. He had the star wheel turned clockwise down so it was more smokey to suit his taste, we normally talk people through setting up for clean power though

Yes exactly, small gains on standard fuelling, larger gains with more fuelling as the extra advance burns the fuel rather than making a smoke show

You said you understood what they are supposed to do, I was showing you how it works on the inside showing it does actually add more timing advance via extra piston travel and we know extra timing advance helps in the mid to high RPM range. As for testing on its own I agree with what you are saying and more testing will be done its just the logistics of finding a standard TDi and then getting it onto a calibrated 4wd dyno that are willing to run land rovers... tricky in the UK as most TDis have been played with and most dynos are in low buildings or owned by people who do high end tuning for themselves so arent willing to run a land rover on the rollers... but it will be done. Probably in the order of Standard, Boost Pin, Timing Spacer, Boost Pin & Timing Spacer then finally Boost Pin with Timing Spacer and tuning. But that would probably be 15+ dyno runs. What I was trying to say originally is that both the boost pin and timing spacer work together as a package so the independent test done by my customer is still valid as a before and after test on the complete package gaining 30hp. For the individual product dyno testing I reckon it the boost pin will get a good percentage of the 30hp increase as its adding fuelling and the timing spacer would only gain a small percentage increase because the increased timing isnt doing much without the extra fuelling but when they work together you get the 30hp... tuning is all about supporting mods tbh and the headline numbers are only half the story. As for genuine customer testimonials here is a start, I am sure more people will chip in as this thread "trends": www.facebook.com/StegsSupplies/reviews

The test showed exactly what the Boost Pin and Timing Spacer did though... it was literally just putting the products into a used disco and seeing what they did... Unfortunately my own testing has been somewhat scuppered by a small collision, but once that is repaired I will be back into further developments rather than borrowing vehicles 😂😂 As for the what the spacer does, here is a picture that shows how much extra the timing advance mechanism can move with the spacer it compared to standard

@Red90 it was a customer doing his own testing on his own truck with his own money the only input I had was to testing method, i.e. doing three runs before and after and averaging the results and other little things to try and make it as fairer comparison as possible. The customer reduced the star wheel pre-load which is where the smoke comes from and the engine was quite worn to start with so I agree its not the perfect test but it was a totally independent test with repeatable results which couldn't be influenced by the retailer (me) because I was 200 miles away and wouldn't be influenced by the dyno operator as they had zero vested interest in the product. A zero bias test. While I understand people want to see the product tested on its own the point of that before and after dyno test was to show the benefit of the tuning package as the boost pin and dynamic timing advance spacer kit compliment each other, meaning the whole is greater than the sum of the parts if you understand what I mean. The boost pin allows less off boost fuelling and more on boost fuelling than the standard pin meaning you can dial in the fuelling where you need it without excessive smoke while the dynamic timing advance spacer kit means you can burn more fuel cleanly and makes the engine more responsive. They compliment each other nicely.

Thanks for the tag Ross, The Original Dynamic Timing Advance Spacer kit for Land Rovers available from Steg's Supplies works by allowing the dynamic timing advance piston in the bottom of the injection pump to use all of its available travel giving you more injection timing advance at mid to high engine rpm. In layman's terms this means the engine will rev more freely, responding more like a car, and it will allow you to burn more diesel without raising your EGTs and smoking out the street. This gives you more clean and cool power. If you want the full details and the independent back to back dyno testing which shows the improvement then you can find them here: www.stegs4x4.co.uk/product/dynamic-timing-advance-spacer-kit

great news! Must feel great to come out of the other side victorious finally!

looking good, keep bouncing those ideas around!

Haha no worries Mike, was just thinking that because all the components are pretty much the same bar the brake system that on the points system you should be grand for an age related plate but I suppose it all depends on who processes the paperwork!

Playing devils advocate, say the engine and box are from "K" Reg date vehicle and the axles are from "L" Reg date vehicle (but are same as the K reg date vehicle) then would it get an "K" reg as the dateable component the engine is that age and the other components are the same spec as those used with that reg anyway (along the lines of the original or like for like replacement on the points system?)

Very well done Mike!

Good luck tomorrow Mike!

Looking good, nice results for the "MOT" test! Good luck with IVA!

Ive had more issues with them sticking then I have ever had with normal defender calipers tbh, even after cleaning up the slider and coppasliping the slider.

To be honest the Disco2 axles are beautifully simple to work on, would be a worthy upgrade if you binned the sliding calipers for more conventional calipers... you get wider stronger axles which are easier to service and you could run some pimping alloys on your big tyres... or some mild offset rims and job done...

Increased track width will be a big bonus to stability and should still keep you as a sensible width for tight lanes like V gully and the gates on wayfarer as we discussed the other day bud. How are you looking at making the rear axle wider? And are you not put off by having custom half shafts if you plan long distance runs? What size tyres are you on again? I know my 37s were pretty close to the foot well on full bump with lock on and -32ET modulars

if its unladen weight is less than 2020kg or so and it either has two rows or seats or is 4wd it is a dual purpose vehicle and therefore can be entered as class 4 as far as I know... I would go for the full 3500kg 110HD weights personally so if you ever need to use the full carrying capacity you can

How do you get axle wrap on a radius arm? Normally thats a term applied to acceleration/braking forces twisting the axle up/down in an uncontrolled manner and distorting a leaf spring. Radius arm just applies force to the chassis giving anti-squat and anti-dive

its only got two choices bud... itl either work or it wont lol

fair play bud look forward to the full test fit!

Nice work Ross, hows the up travel of the lower links against the radius arm mounts?

Looking good Ross!

Thanks Shane, I also have a Disco2 daily driver and a Defender build that I am still contemplating suspension ideas on so any pics you can get will be great.

fair enough, any pics of the finished product?
