No sir. All it does is just raise the rail pressure. There's no wire splicing needed, nothing elaborate like that. Besides, most Isuzu mechanics are familiar about the Racechip Pro or any other locally-sold diesel EFi chips, and they don't even tinker them when they do servicing.

However, if you're still pedantic about it, all you need to do is remove the kit from the engine bay and plug the dummy chip (which also comes with the tuning kit). Just remember to cover/seal the dummy in case you will have your engine washed by the service centre after the maintenance work been completed.

This is how the Racechip Pro looks like, plus you have the lovely Ms. Mika-niko Umali install it for you

Goodluck!

Our two Dmax's (one old 4JH1-TC and one current model 4JJ1-TC) are pretty much just bone stock. Just use the stock Goodyear tires, use good engine oil (e.g. Mobil 1 Delvac Gold 5W-40), use high-Cetane diesel fuel like the Shell V-Power diesel (especially for the commrail model - the 4JJ1-TC), always make sure that you run a clean air filter (i change my OEM air filter every 10,000 km usage since i always prefer new ones), and you're set to go.

By the way, my 4JJ1-TC Dmax is mated with a Racechip Pro diesel EFi tuning chip and it runs great yet is thrifty on fuel....

Cheers!

yes sir 4JJ1-TC, anong comment ny dito sa engine oil na to,mukhang maganda eh.

Chief Cooljay21,

Don't also know anything more about Total Petroleum company synthetic oils, apart from the fact (again) that it's another Frenchy fries oil hehe

Just read through this that i posted in the other Isuzu thread, somehow you can deduce which parameters you should also be looking for aside from just the outside label in canister that says anything like 5W-40 or 15W-40 etc etchetera.... Oil weights written in the bottles can only guide you so much.... You really have to read through the product information data sheet (not the MSDS - Material Safety Data Sheet) to know more about your oil.

....Just like the Motul oils.

Just make sure apart from a good viscosity index of the oil, which is computed from the range of the difference in centiStokes of the oil at varying temperature ranges, another good indicator in choosing your oil is the amount of Total Base Number (TBN) to cater for say the sulphur in our Euro 2 fuel supply here in Philippines.

I am using Mobil 1 Delvac Gold 5W-40 that addresses the (3) parameters stated above, amongst all other factors. But prior to this, i came from Isuzu Besco 10W-30, then Motul Specific CRDi 5W-40 and Torco SD-5 15W-40. If there is a supplier of Amsoil in Philippines, i would like to try one of their engine oils for diesel cars.

Cheers!

There are 3 possible causes that I know of. One is your fuel filter might be contaminated with water which was caused by dirty fuel. 2nd is the SCV or Suction Control Valve must be busted already. 3rd and the most expensive of the 3 is your EGR might need to be replaced.

I have experienced it firsthand too. The first time it appeared, the engine felt weak and died. It took I think another week then it lit again. I brought it to the dealer and found out that the SCV needs to be replaced. I noticed that once it lits, the engine will die. It solved the problem then after some thousand kilometers, it lit again. But this one is different. It never disappeared or unlit anymore. After almost 25k+ kilometers and 9 months of it on my dash, the truck is still running properly. The dealer said it's the EGR but I never had the chance to have it replaced since the first time, Isuzu Commonwealth told me that it would take 3 months for that part to arrive. After 4 months I followed up, they told me that it's still not available. Then the months kept moving that's why up to now it's still not fixed. But the car is running ok anyway so I am not really bothered. I even brought it to Ilocos, Quezon, Tagaytay and to lots and lots of places and it never failed. I just don't know for how long it could hold, though.

Better to just bring it to your dealer so they could diagnose the problem since they use a computer to analyze it.

Got the same issue with my 2004 LS at 93K Km. Isuzu casa required me to replace oil cooler but they have no stock that time and they quote way too expensive at Php24K. How an oil cooler related to this problem? My truck is running perfectly anyway except that after the last PMS, the engine sometimes turn off couple of times. It's been 3 months and it become normal now.

Anything to worry about?

thanks again sir!

Mga sir, double check ko lang kung eto yung part no. ng K&N filter for Isuzu Dmax (4jj1): K&N E-2023? Thanks!

Parang yan nga yata sir ang correct part no. Will you get it from Banaue Avenue?

Be aware lang sir since i still have my K&N but have gone back to stock OEM air filter ever since i used the K&N for quite a few instances - mabilis dumumi ang K&N sir lalo na sa air environment natin. Maganda yan sa mga bansang hindi mataas ang particulates sa hangin.

You may try sir but you have to clean it quite often if you're particular about the cleanliness of your filter, as each short time it gets dirty, you'll notice that it's almost just the same response you're getting from your engine when using the OEM filter.

I haven't tried Hurricane air filters though.

Goodluck chief. Cheers!

**jgvus** · November 2nd, 2012 11:15 PM

Thanks sa advice, I'll explore on hurricane filters na rin. Sa banawe pala ako bibili. Thanks chief!

Why this good bloke chose the D-max over any other UTE for his avid outback riding around Oz.... Here's his heaps of no none-sense reasons why, of which we Isuzu owners know of already anyway haha!
