Get Yourself an SQL Update for Christmas

[SwampFox55]

Gentlemen,

At the 30,000km service in September my auto MY12 PB had the latest SQL update loaded. After 8000km, most of it towing, I can confirm it has made such a big difference to performance, it’s as though the car has a new engine. It’s noticeably quieter and has improved power, torque and driveability, the transmission is holding lock in 5th better than ever before, fuel consumption is improved and there are no longer any cycling diesel combustion noises at 100kph in 4th – tick, tick, tick! It’s now just as smooth in 4th at 2650rpm, as in 5th at 1950rpm - big difference. Do yourself a favour and get it loaded ASAP, even before the next scheduled service. Call it a Christmas present to yourself.

Cheers,

Sql ???

ECU software update on normal terms. SQL is standardises query language in the geek world.

hmm...at risk of exposing my my geekdom, in the geek work doesn't SQL mean Structured Query Language?

Anyway, many moons ago a MMAL service manager touted the SQL. The impression I got from him is it 'adjusts' the ECU to compensate for differing injector performance...as they get older.
I think it means SeQuence Learn. (I look forward to being corrected though .....to shed my exposed geek )

Hi m&m,

A quick check of my with my silent online cyber BF and I found both "standardised & structured as definition of the "S" in SQL and there is absolutely no reason the Mitsubishi's Geeks have not invented their own meaning of "SQL".
After all there are no ISO Standards for all abbreviations.

Whats the difference between a mechanical engineer and a software engineer?
When a mechanical engineer gets it wrong it is called a failure and they pay, when a software engineer gets it wrong it is called an upgrade and you pay!

Wonder if we are talking about the same thing. As the post above reads the small quantity learning should manage itself somewhat. Also thinking in the service book for the Paj it says inspect sql rather than carry out manual sql.

[coughy]

yes that is the same thing if you had yours back for the service campain it would of been done then as im is much better after the service campain with the new coolant and radiator cap..

I won’t contribute to any of the misinformation floating around about the Challenger engine’s SQL.The fact is the Service Manager told me they do an ‘SQL’ (standardized query language, injector small quantity learn, who knows!) for the injectors at every service and the last version was an update.The program they loaded made the difference to my car’s engine performance.Coincidently, it improved very noticeably, the transmission’s operation in the locking of 5th gear under load (towing), I suspect via a difference in throttle position (demand on the transmission) versus power delivery.When I tried to delve deeper, just as background info for me, I met a brick wall.I expect this is company policy as there is currently a big push from independent mechanics across Australia (ref. Cars Guide a couple of weeks ago) to get access to up to date software from all vehicle manufacturers, so far without success.That keeps us all going back to the Dealers of all brands, for expensive services, if only just to get the latest software updates.One can understand this data is gold for the Dealers. I actually have no issue with this because the manufacturers have spent the big bucks in developing it so they need to recoup their outlay and recover a profit.They’re in business not a benevolent fund, before anyone gets their nickers in a knot.

With regard to the injectors specifically, I had previously suspected it compensated for small variations in wear between individual injectors to bring them all back into line, as for minor variations in the quantity of the squirt.I have a suspicion that cloud point crystals may accelerate wear and this may be uneven across a set of injectors.I thought this, in combination with high cloud point fuels (eg QLD versus VIC or summer versus alpine blends) used in cold weather (even just left out on very cold nights) could be the reason for some brands faring worse than others, eg as per Hilux and Patrols a few years ago.However, this service proved it did much more because it made the engine perform better than ever before; not just taking it back to a baseline, as new.

I bought this car at 14km so I know how it behaved from new and it was never as good as it is today.The effect noticed is quite separate to that of the tappet clearance adjustment which also improves performance, as well as quietening tappet noise, proportional to rpm.Maybe there are some diesel mechanics with the relevant expertise that can elaborate on the specifics of the program but I was told by The Boss, that they ‘know nothing’, they ‘just load what Mitsubishi send them' but, ‘it was an update’. That was the official line, across the counter, to a very happy customer.

LOL. The software industry is one of the few that allows a product the be delivered which is faulty, but there is no accountability to fix.

Thanks for bringing this up swampfox. I just had the 30k service done last fri along with the recall on the overheat and noted was the ECU upgrade . I had not driven the challenger for a couple of days as the better half took the car in and picked it up . A couple of days later she said that the car was running differently and maybe I should drive it and see if all was ok. After clearing the 40KLM / Hr area I put my foot down as I normally would and the bloody thing took of like a rocket and held the gears a lot longer than normal and seems a lot stronger and a little bit growly when using more throttle .
Initially I thought something was wrong and was getting ready to head back to dealer , but thought it might be going thr"u a re learn and over the last week it has settled down , or I am just getting used to it.
If driving with minimal throttle as we normally do then it seems like before.
We wont be towing for a couple of months but will be interesting

Swampfox55,
You are indeed lucky. Its not often you get an improvement like that for 'free'.
Will be interesting to see if others get similar improvements.

When was this SQL update released. I had my Challenger serviced about a month ago but have been away since then so not driven it.

I'd say the automotive industry is the same. They knowingly produce cars with faulty speedo readings! And have no accountability for it! Surely in this day and age some smart monkey can work out an accurate way of determining speed!

mudguard1,

I think we just get used to the new normal and don’t pay much attention unless things bug-us somehow. In my case I’ve got some comparative data, so there’s no question about the changes:

1. Before the last service, when towing my 1.5T pop-top it would unlock from 5th at around 100kph, with a 10kph headwind or, at the slightest increase in gradient. It used to drive me nuts!
2. After the 30,000km service it would tow locked in 5th at 100kph in 30kph headwinds and up 3% gradients. I could actually tow at 116kph indicated (110kph limit) on the Pacific Freeway to Sydney up the lower slopes, locked in 5th. This was just unimaginable before and I’d be shifting all the time on the Hume and Pacific in the past.
3. Before the service it would make cycling detonating sounds (5s intervals) clean and towing in 4th at a steady 100kph and was particularly noticeable with cruise set – there was something wrong. I even took the Dealer’s Foreman for a short towing trip with my RV for 50min, last Sep before the service, to demonstrate the sounds. Now clean, it’s like a normal engine, with no cycling combustion noises. I did most of the last RV holiday at steady 100-110kph when on flat ground in 5th , so I can’t say for towing. However, there is no doubt in my mind that there’s been a significant change.

Now, if I hadn’t written these things down, I’d probably have forgotten them with time after the service, even if the improvement in performance was noticed at first. Just human!


m and m,

It wasn’t free. I paid $595 for it, amongst other things.
