Dyno tune

Just thinking about taking my 100 series to get dyno tuned, it has an turbo and have had problems with getting hot. I was wondering how good the dynotuning works and would love to hear all good and bad stories from other members/visitors.

How hot is hot ? Some vehicles run hotter than others

What is the EGT ? My Navara runs at 590c a little on the high side but acceptable according to Dyno Tune @ 100 k speedo ( thats after the turbo )

Does it have Turbo Lag ? I did have a bad case of it from new, and the local Nissan agent refused to believe me, or do anything about it, so I took my business elsewhere, and had it fixed @ 20 k on the speedo. Never have been back to that agent. I have a great mechanic, and went back to him, and is about 1/4 the price of the Nissan agent ,, and is more thorough..

Do you just switch it off after a hard drive ?,,naturally you have to let the turbo cool down, I do not like the idea of all that heat under the bonnet, and not to mention that the turbo is still spinning, so it needs motor oil for lubrication. A turbo timer will help there, if not a 2-3 munite wait before shutdown.

These are some of the questions that you need to ask yourself, ?

Yes a good Dyno tune may fix all, and with a bit of luck get your LC 100 up and running real good

Cheers mate

Dont know what my EGT is, but I imagine HOT, the car gets very hot, not just a bit like your suggesting. I have an intercooler which is in front of the radiator which i dont like much, but i still dont turn the car off for atleast 5 minutes after a long run. I hope the dyno idea works, cause i've spent alot of time and money trying other things to stop it getting hot. Thanks again for your advice.

Had the Troopy dynotuned last week- and very impressed with the results. But like anything- it's not how good the machine is- it's how good the operator can read and diagnose the results !!!

Cheers for that, I hope im impressed to, did you do the dyno test for a specific reason, or just to get a bit more power or something?

G'day fishy
The dyno analysis is just part of the diesel shop's tune up procedure. Sure, a good tuner can pick up performance on a road test- but I think a dyno can put the engine under various loads and readings can be gathered for optimum performance (& economy & reliability). Things like injector nozzles are checked on another bench, but fuel pump efficiency & turbo operation can be adjusted more precisely with the operator monitoring the readouts.
Also, it's handy to have a reading before & after just to see what differences can be achieved.
Let me know how it goes !!!
