Is your Patrol "chipped" - Page 2 - Nissan Patrol 4x4 (Africa)

Ja die manne met lang wit jasse maak goeie krag. Hulle boost 2 bar, onthou hulle het die regte fuel ook. Dan blaas hulle gas ook.
Die 4.8 werk mooi met sy eie manifold. Die branch maak nie groot verskil op n std engine nie. Dit maak wel die hitte onder die bonnit meer wat nadelig is.
Die ontbranding kan gehoor word wat die kar harder maak. Dis mooi vir party mense, my inkluis.
As die kar cats in het, gaan jy groot gain deur net hulle uit te haal.
Gewone 4.8, waar die front pype bymekaar kom moet jy hom choke. By die 2 in een vanaf die frontpipe sit jy n 57mm pyp in tot by eerste box wat n 63mm box is. Van die eerste box bou jy die res 63 met nog n box tot agter. Die 4.8 is std n 63mm pyp so jy kan net die agter box uitgooi en hom n freeflow maak. Dan ook die 57mm pyp voor insit.
Die kleiner pyp gee meer bottom end en steel nie krag bo uit nie. Ek het al 50mm ingesit en die kar werk goed, dis net te klein vir n groot engine, die pyp gee n blaas geluid af.
Anyway jy kan self 76mm toe gaan agter halfte van die stelsel, maar die klank gaan afhang van jou. Jy kan met n 3 box stelsel opeindig, wat dan duur raak.

Irrespective of what Frans has said, remember this: a chip is primarily a system that allows you more control over the factory settings. Yes it comes with a set of "factory" setings, but these are not necessarily ideal for your engine/environment, and may be little better than the original.
As such, the skill of the person who enters the new values is crucial. Do it wrong and you can very easily end up with a broken motor.
Frans is one of very few tuners I have met who will tell you not to waste your money. Some others will sell you the chip, then make some adjustments that they know are not ideal in terms of reliability, just to show a gain on the dyno and thereby justify the money they are charging you.
Furthermore, it is very important that they understand your usage of the car/engine. If the timing is advanced to the maximum, and you then get lower-octane fuel in your ramblings in darkest Africa, you could brake it too.

strontttt kom by die diesels - party "Dyno" tuners willi diesel doen'ie - -Agarob was deur Dastek self getjip en getjune -- maar die dag het hulle my kar uitgesoek om k** droog te maak
[toe ek gaan vra hulle die gemors regmaak .. natuurlik teen hulle koste -- het di eienaar smaalend vir my beduie - "Gaan gerus Hallo Peter toe .. dis gratis advertensie vir ons..
2 maande later het Agarob ge hand-granade.
Ek het Kobus se 4,5 gaan afhaal nadat hulle ge chip het [hy was besig] Maande later het Kobus nog stront met sy 4.5 gehad.
Ek weet nie of hy hom elders ingestel gekry het, nie.
3,0 Diesel ?? Natuurlik sal ek hom chip. en EGT. en freeflow en branches en gasflow .. dan is daar weer n BOEZMAN op ons paaie

Ek het n 2de hand 4.5 goedkoop. Wou hom nog laat chip want ek dink die krag is min. Een dag toe ek n nuwe alarm stelsel insit kom ek op n dastek unichip boksie af , so al die tyd was hy gechip. Kan die goed met tyd self uitsel sodat ek weer moet laat dyno?
Ander vraag om n aftermarket management op te sit soos gotech of dictator is dit nie ma beter as n chip op standaart management.
My patrol het 458000km op en kry 4.5km/l ok met 33duim bande en n chip . Wat sal hom beter maak?
Life is a journy, enjoy the ride

Ink, ek dink op 'n 4.5 met 33 duim bande is jou brandstofverbruik min of meer wat jy kan verwag. Ek kry 20 liter per 100 km met my 4.5 met 33 duim MTs.

Joshj, om n diesel lewendiger te maak, is die maklikste om die brandstof meer te maak. Hy trek dan beter en rook ook meer. Met die nuwer diesels wat almal turbo's het en elektronies beheer word- kom die unichip in die prentjie om toe te laat vir enige verstelling. Let wel enige verstelling. Met die ouer diesels het n skroewedraaier die werk gedoen.
Om jou vraag te antwoord: Meer krag vir n diesel is meer brandstof. Ook meer boost om die lug/ brandtof verhouding reg te hou. Dan raak hy sterker. Omdat hy meer krag het ry jy meer ligvoet om die selfde werk verrigting te kry as voorheen. Dit spaar diesel. Maar, die ontbranding word warmer. En alles word natuurlik gestel on veilig te bly, boost en egt's. Diesels breek van 750grade af. Ek probeer nooit oor dit stel nie. Ek het al meer as 800 gesien en die engine lewe.
In elkgeval, ek sou nie self die nuwe 3.0l ZD30 chip nie. Net omdat hulle n geskiedenis het vir breek. Die manier hoe hulle breek is hoer ontbranding temps. En die chip gaan dit aanhelp om hoer te raak vir meer krag.
Jy kan die intercooler vergroot en n vryvloei uitlaat opsit. Dit sal die kar help met performance. Hou net die boost op, party karre se boost klim met n vryvloei uitlaat.
Ink, die chip verloor nie sy inligting nie, selfs le hy op n rak. Jy kan altyd na n Dastek agent gaan om te kyk of hy wel reg werk. Net iets belangrik op n 4.5
As die kar gechip word met n dastek chip, word die distributor geskuif om meer spec te gee vir timeing verstelling via die chip. Nou as jou mechanic dit nie weet nie en hy diens die kar, en hy let op die distributor lyk verkeerd gestel... As hy daaraan draai is die hele map daarmee heen. die map raak nie weg op die chip nie, die verhouding gaan uit.
Die bogenoemde is nie vir popcorn vreters nie.

Thanks Frans. The above has been most informative.
What are your ideal specs for a 4,5 exhaust? I have a 3 box system put on by Maus about 12 years ago and it seems a bit restrictive for my liking.
For the guys with the older petrol Patrols if it starts getting sluggish at lower revs and pienging check your leads from sparkplugs to distributor. Nissan leads are just over R 2 k but ex Japan with 3 week plus wait. "Bougi Cords" are available at R 600 per set. And the difference between the old(if shot) and new is priceless. They may look fine like mine did, but touch them while the motor is running and you will find out very quickly if there is a problem.
Mine also had a chip which was installed over 10 years ago but the previous owner removed it and said that he had felt no difference with or without. Probably because the timing had been set without the mechanic knowing about the chip.
Frans - The VG30 in the Hardbody and Sani gets big gains at low to medium revs from a chip if you have opened up the breathing, reprofiled the cams and gas flowed the head but also has "old school" electronics. Is it just the aircon system that is different and if so is there no way of changing that setting so that it does not advance the timing when the aircon is switched on in the Patrol?
I am looking for a nice gain between 2000 and 3000 revs on the 4,5 and have been thinking of going the chip route but am not sure.

The exhaust for the 4.5 is simmilar to the 4.8. Althou a 76 mm wont make a huge diffirance.
50mm to 57mm choke in the front. Remember the first box to be the size of the rest of the system. 63mm to the back with 2 boxes. This made the best power vs sound.
I would like to add,. the choke, some people would pull up their shoulders. Yes its wrong if the engine was reving over 6000rpm.
The VG30, the same for the distribitor/ chip setting. The Ac does not make a diffirance on the timeing.
Those 3l v6's are very underrated. Its a strong engine. Only becarefull for to wild on the cams , it will steal power @ 2000 to 3000 rpm.
