The "Official" 5.7L Supercharger Problem Thread

[beboff]

I have just talked to a reliable source at TRD...they said the fix will be ready in 10-15 days!! They asked everyone to be just a little bit more patient with them. They are aware of the problem that some of us are having.

[docderwood]

I hope the above is true. My only question is why can't TRD just tell us that when a prospective or current customer calls????

Or are they waiting for Spring to be here?

Haha - I wonder the same thing..."just a few more weeks guys, wait no, what's the first day of summer?"

Im not sure what you mean by this? If its happening to alot of people...then it IS vehicle specific.

Its the reflash causing these problems...I promise you.

[dirtroad_devil]

ok. well, it's still up to trd. if.....someone had a tune for us i would say screw trd, but there's not antbody. mhp had our hopes up for a while but that died out. just got off the phone with gadget at urd....he said they have on in the works (6 months out at best).
regardless, it's trd's responsibility. they got this far so they should be able to get us mapped for an across the board re-flash! with the learning ability of the computer and all the sensors providing constant info. regarding driving condition, driving style, vehicle condition, altitude, atmospheric condition,......temperature....etc. there should be no problem! in other words...the tundra, like any other vehicle is set like this right? in other words, if you take your n/a tundra from sea level and drive it across the nation.....up and down hills in different temps, etc....it will perform like a champ. because they set the parameters right?? and the computer is doing what it's supposed to do, constantly adjust and compensate....for maximum performance!!!!!! ok, then if thats the case, then why can't they up the 'parameters' (layman's term) for the s/c properly?? some may say that it's not so simple a task for the engineers....but that's their dang job!!!
i could go on and on......but, look at the vehicle as a whole....an engineering wonder! and they can't fix a seemingly simple problem like....re-arranging some ones and zeros!!??? c'mon. they did the first re-flash for the s/c.......uhhhhh, see my point?
erg.

[beboff]

This is one great S/C.........If they would just get ride of the cold weather TQ Management!!!This thing is faster than most sports cars!

[McColl]

was considering a s/c for in a 6-12 months but i think ill wait a while i hope they do something for you guys

Seriously? The only thing I agree with is that it will NEVER be as good as a[n] aftermarket tune. This supercharger is OEM and sold through the dealer. The canned tune should provide what Toyota advertises under any climate conditions. Of course an aftermarket tune is going to be better. A lot of tuner products are sold only through dealers who CAN tune for the product being installed. That's an apples to oranges comparison. This is like a guy buying a F-150 lightning (or any factory boosted vehicle) and when if it runs like crap somebody tells them they need an aftermarket tune. An OEM quality/ "performs at an acceptable level in any driving conditions" tune was supposed to be part of the package. An aftermarket tune that runs like a raped ape in South Carolina may not work well in Saudi Arabia. That's not what these guys are looking for. They are looking for what Toyota advertised. That S/C is advertised as what? 500, or 550 HP? That is MILD. That shouldn't require an "aftermarket"/ragged edge tune. There are guys making much more than that with little 4.6 ford motors and similar superchargers (obviously with much more aggressive/less generic tunes). This mild boost should not require a ""specific" enough" tune to require aftermarket intervention.

I think we all recognize its the re-flash.

My point is, since its happening to a large percentage of owners with the S/C, its wider than just a specific vehicle - so its NOT vehicle specific. I would call it a vehicle specific problem if one or two people were experiencing this problem. You could drill down to their vehicle and figure out why the re-flash is cutting power and it would most likely be due to a wider ranged sensor than designed for in the tune - That, in my opinion, would be vehicle specific. I would be less likely to blame the tune in that case than what we are experiencing now - even though I agree that each individual vehicle still needs a custom tune.

thanks N2O,
you said exactly what i said...or was trying to say. only you did it with better clarity.
2 more weeks..........hopefully i can remember where i parked my tundra. almost forgot i had one it's been so long since i drove it...much less looked at it.

[Super Werty]

The difference is this...

The Lightning was designed from the factory to be boosted. It was well thought out.

TRD rushed the development of the TRD blower for the 5.7

I mean think about this for a second. They talked about the 05 tacoma supercharger for years and years, and it finally came out late 07. Took 3 freaking years. The reflash works on stock vehicles...at least no one has had power loss at 4000rpms or at any low temp

The 5.7 blower came out within a matter of weeks after the new tundra was unveiled. That means they didnt do enough testing. The reflash was a quick bandaid, and they knew it.

TRD will probably fix this issue of power loss, however none of you will ever know whats really going on until you get a wideband and boost gauge. I find it ironic that its taken this long to get fixed...almost makes you wonder if they really are waiting for warmer weather.

Tuning my truck took 30 minutes...not 30 weeks

Im just saying...anyways, hope it gets fixed for you guys, but Im just trying to be realistic here

If you have a s/c 5.7 then you really just "need" to get it tuned by gadget. He is very sharp and has been into the s/c toyota 3.4s for over 10 years. I had seen him around from the very beginning (I had one of the very early 3.4 s/cs on a 97 tacoma) and he is very widely respected for his work with the toyota 3.4 and 4.0. It won't take much time until he is the "go to guy" for us with the 5.7 in the tundra. The "fix" by TRD will probably be mildly better than the tune you have now, but why settle for an OK tune when you can get a real dyno tune and lots more power.

I am trying to stay away from the s/c on my tundra as fast cars/trucks seem to lead me to trouble. I have had a number of very fast (10-11 sec)street cars...ttmkiv, n20 ls1 t/a, terminator. Right now I'm concentrating on building my 04 tj for 4xing rather than building something fast.

thanks for the post.
super werty referred us to gadget already. i called and talked to him yesterday....no such luck. he said he's aware of our problem but doesn't have anything for us; maybe in six months but, nothing right now.
i still feel that if all these tuner folks can work their magic, the engineers at trd that get paid the big bucks should be able to do something for us. afterall, they have all the original information and such right there in house!!

[BEAST-TUNDRA]

It has been a long time, and I still have not recieved any info from the Dealership. So I went down to speak with the Service Department today and all that was suggested is to file a complaint with Toyota. So I did; not sure if that will help this cause.

[thumbster]

So if it really is the ambient air temperature that's causing the truck to fall on it's face above 4000 rpm, then what's keeping someone from tricking the air intake temp sensor a little?
