i made sure it wasnt tuned to its peak just incase of situations like these were i could run optimax or premium unleaded if C16 wasnt available, ( which it wasnt).  so conclusion being, i ran 11.5 still with traction problems on prem unleaded, not at its maximum potential. :kick:

Well if you were still able to run the car at full throttle, through all the gears, at maximum load (as per drag racing), with PULP with that tune and NOT get severe detonation, then all you did was WASTE a tankful of C16 last week :(

Why in the world you would pay $150 for a drum of C16, and then get it tuned so you could run PULP???? :):D

Robo,

The amount of wheel spin I was getting was very noticeable from inside the car, the back end was wiggling around all over the place through 3rd and even in 4th, so much so that the commentators made mention of it. The other lads there watching could hear/see it too.

i like your comment about "Why in the world you would pay $150 for a drum of C16, and then get it tuned so you could run PULP???? " its an easy answer, ( casue i can)....... :rofl: :rofl:

but seriously at full throttle in 3rd gear it was fluttering a little, but not detonationg, either cause of sparks i changed just befor racing or the tune, will try again soon and see what happends.

I suppose you thought you'd come away sounding rich and powerful from that (because you know.... None of us can afford C16), but instead you came across as a chump who has absolutely no idea about cars or tuning. :slap:

how can u tune a car for c16 but still be able to run pulp fuel when u want and still have no problems.....what comp are u running? who is ur tuner? wreckedhead? (if u tune for pulp fuel u would get to a point where it has reached its limit because of its octane rating.....when on c16 the octane rating is alot higher therefore a more aggresive tune....how do u accomadate for both, without comprimising max power or detonation im just a little confused... ?? plz explain

Exactly.

The car should be tuned with so much ignition timing for C16, it would pretty much grenade itself if you ran it at full noise with PULP.

So basically the tuner doesn't know what he's doing, and wasted all that C16 by tuning such a stupidly large margin of safety into it that wreckedhead was able to run PULP on the same tune, effectively wasting all that C16.

amu,

It's amazingly simple to tune for C16 and then run pulp. It's achieved using an ECU that allows multiple maps. It literally takes all of 5 sec's to switch from the 98RON map to the C16 map to the LMS map to the cod liver oil map (ok so that last one is stretching the truth a tad). I have 4 maps in my handset that I select from depending on what I'm doing. At the drag strip I select my "Valet" map, hmmm.... maybe that's why I can't seem to rev over 3,000rpm!? :)

But seriously... if wreckedhead is using an ECU that has a multi map option then he CAN use C16 and make full use of it. Just as easily he can fill up with 98, select his 98RON map and be safe in the knowledge the timing is not overly advanced (depending on how agressive the tune is). If wreckedhead has only one map to choose from then I'm as baffled as the rest of you!?

whatsisname, amu and Merli:

JETT is running a Power FC tuned by C&V.

Does that answer some questions?

Adrian

Nope.

Unless he has an FC Datalogit with the ability to store and load multiple maps, there is no way he should have been able to use PULP on a proper C16 tune.

i might be a little neive but im not stupid when i had the tune done i made sure it wasnt tuned to its peak just incase of situations like these were i could run optimax or premium unleaded if C16 wasnt available, ( which it wasnt).  so conclusion being, i ran 11.5 still with traction problems on prem unleaded, not at its maximum potential. :kick:

Interesting. No mention of multiple maps :)

Too many holes that I can't figure out... I'd love if you're able to explain it to me wreckedhead, because I'll obviously learn something about tuning if you're honestly able to make what you're claiming...... work.

    • We have some genuine Japanese legally decommissioned car number plates now in stock 🙂 Add some legitimately obtained JDM style to your Skyline or other Japanese model, or simply as a garage/man cave decoration! About the 40mm hole: The Ministry of Land, Infrastructure & Transport in Japan recognised the popularity of keeping decommissioned plates among car enthusiasts and came up with a method to "destroy" (or render them unusable for street use) while still retaining their collectable/usable value for display etc.  We have 40mm hole covers available to cover the hole nicely with a Sakura motif, which are also available in white in (very!) limited quantities, however they frequently sell out. Please let me know if you're wanting one or more of these and I'll check availability. The Sakura motif covers are more common. https://www.oemsoko.co.jp/products/genuine-decommissioned-japanese-vehicle-number-plate-set-su-7515 https://www.oemsoko.co.jp/products/genuine-decommissioned-japanese-vehicle-number-plate-set https://www.oemsoko.co.jp/products/genuine-japanese-vehicle-number-plate-400mm-hole-cover *Please note that we can't obtain particular number or area name (eg: "Gunma 500 Fu ・86") if requested. All plates are provided as they become available after decommissioning. 
    • Ah, fair enough. For the IAT, I'm using a legit GM sensor that was used on the car prior to my current build. I'll get another wideband and IAT ordered and follow up when they show up. Thanks for the help.
    • You shouldn't need to massively fatten up the mixtures for cold conditions. For one thing - 0°C is not that cold. For another, the Haltech will be using the IAT sensor to tell it how dense the air air, and calculate the correct amount of fuelling. Then the cold start enrichment is added as a % on top of that, so it should scale with the main fuelling. You might also doubt the IAT sensor at this time. You're not using one from an RB26 are you? Using a nice Bosch sensor or similar? Happens. Some wideband units take great pleasure in killing their sensors. Put another wideband in the tailpipe and compare. Or just swap the sensor to a brand new one and see.
    • Oh, my misunderstand. When the car was running, it sounded ok, but if I gave it any gas it wanted to die but caught itself afterwards. It's very different from how it was a couple months ago when it was warmer outside. The logs show that the AFRs are better during, what I assume, is warmup enrichment. Because it's cold, and air is more dense, should I work on the enrichment bit?
    • yess of course im not using 2nd hand parts from my spare engine, but the place where i live is hard to find parts for the RB20DET ,but for the RB20E is everywhere including new ones and a lot cheaper ,because for the RB20DET you have to order it overseas to get one and it cost a lot of money 3x the price to be exact. so i ask this topic because if i can use the new ones but for RB20E is it compatible or not. if not im screwed haha, not totally screwed but i have to save a lot of money first before i can begin repairing my engine, thanks for the information before.
