Td5 Tuning

[pete300tdi90]

Hey, got a Td5 but think i little more low down power is needed for pulling the car through deep deep bogs and steep steep hills.

was thinking a 2nd hand chip off ebay, or a remap, or something else... what do people suggest? and who is good?

I like Twisted Performance as they seem to do some lovely trucks, but price is also an issue, what are peoples opinion?

thanks,

Pete

IRB or Bell Auto is the consensus :-)

[pete300tdi90]

IRB hahahaha. i think not. (bad experience... will go elsewhere this time)

IRB hahahaha. i think not. (bad experience... will go elsewhere this time)

Td5 alive, BAS or td5inside.

Spill the beans then or pm me

I dont want to bad mouth companies... just had poor work and poor customer service there. and seen same again and again.

so do people think re-maps or chips are the way forward? (i dont want to go fast, just more grunt to spin wheels gently and continuesly)

[landroversforever]

If it was me, I'd go IRB from other recomendations, and I would have a proper re-map, not just a chip.

[Anderzander]

BAS remapped mine - I asked for a smoother curve and more low down torque, and within the limits of the current turbo, he did that.

Pete, why are you bringing this up in a tuning thread... He did not tune your 300!! He rewired it and added the extra's you wanted. Can you really fault the work he did? You used it as a selling point when you sold the truck didn't you? lol You could fault the time it took and not being able to contact him.

I guess he could have rushed the work and done a poor job in the time frame originally quoted but he didn't. It may have taken a while longer than you planned but he didn't charge you for any of the extra jobs (and time) he had to do including replacing all your core plugs after you let the engine freeze..

Airing your dirty laundry in an unrelated thread without the facts doesn't help anyone.

Anyway... I thought you said tuning was unnecessary

Second that!

[M&S]

I never thought a remap would be "needed" with the TD5, but I had my TD5 Disco fully loaded (probably a bit over) the other day and long uphills on the A1 had it struggling in 4th gear at 50mph. I then realised why people may consider a remap if they were towing a lot etc.

The problem I still have with remaps is the "damage" they cause though. Do a search across the web for TD5 engine failures (head gaskets, exhaust manifolds, etc) and a very large percentage of them are tuned vehicles. That worries me

Have a look for a local diesel tuner. There are a few around here, I'm sure there are around you. Two were offering a half-price offer, so remaps for £199.

I am NOT recommending these as I haven't tried them, but here's an example of a few local to me, must say I'm tempted at £199! :

(If anyone has used teh above I'd be interested to hear your experiences)

[nicks90]

i agree with M&S about engine damage on heavily or badly tuned td5's

stands to reason really - BUT - if you do a mild tune and its done correctly and all within the original landrover engine tolerances then you wont have a problem.

Been running a tweaked td5 disco for over 40k miles and its still ..... no i aint saying it.

however it does transform the car, tows superbly and i get marginally better mpg on longer runs.

[Anderzander]

There certainly seem to be a number of badly tuned diesels about - big steps in the power curve, over fuelled through a lot of the rev range and no doubt pushing the EGT dangerously high.

I wouldn't be surprised to see the problems relating to combustion temp problems.

Third It!

Also, on your truck pete, you will need a chip, not a remap, as your trucks quite early, as you will have a non flash ecu.

Heard that the plug in chips arent very good at all, so would probably stay away from them!

If you don't want to go down IRB route (im not saying anything about IRB, ive had very very good service from them since dot, however i dont want to be involved in this slating match!!) Then I drove a JE engineering mapped truck yesterday, that went really really well!

same. which is why tom I dont think you should tune them! I dont want a tune like you or grant, i want slightly more low down power to keep the wheels tuning, no more speed.

Just Remember to take the handbrake off first

There is a reason engines produce the power they do out of the box, a lot of people spend a lot of time tuning and testing engines before we even see them to ensure they are safe.

The reason some people don't see damage will be because the engine is hardly used in the 'tuned' range. As mentioned above the biggest issues are always temperature related, the stock manifolds and turbos found on all engines will be made out of a material chosen for the highest temperatures the designers expect to see. Therefore pushing past this can cause the materials to become plastic and deform perminately.

Tuning needs to be done with care and with EGT a paramount concern. If you need more power ensure the hardware is up to it.

Low down torque pete is limited without big boost! Low down boost is hard to achieve with only one turbo! But I am sure there will be improvements to be had!

Anyway rant over!

Not gone for 'speed' I wanted more power across whole rev range for greater dirvability, though I now have too much for my liking lol. I have to be weary using full throttle so that I don't over boost (which can happen with a strong map) and without a boost box the ecu doesn't like this which causes the ecu to revert back to 'standard get me home' map temporarily until you restart ignition.

Without an upgraded manifold the increase in egt with strong maps especially from cold start and the increase in temp range that subsequently occurs when you push the engine when cold can cause manifold warpage. I have a strong Stage 2 with an upgraded intercooler but am planning on getting this taken back to a standard Stage 2 or slightly less next time I visit Porny. It goes like **** off a shuffle but I don't want to have to have to buy a boost box to negate the overboost issue or see the point of having a stronger map than I need or use lol

A simple Stage 1 with perhaps a stronger off boost map, decat and egr removal would make a huge difference to JD Pete. I thought you could map pre flashable ECU's but it requires a chip change. Isn't this what was done to yours Grant?

[martifers]

Agree with Mocha on that point. I don't expect my engine to have the same reliability as it might as a standard engine, that would be ridiculous to expect this, (huge amounts of money are spent on engine testing and development) though with any engine it depends how you drive / abuse it.

[Anderzander]

Its also worth stating that many vehicles emerge from the factory with very conservative maps - and in the right hands can safely yield much smoother curves with higher figures too.
