Which race fuel are you using? Any dyno sheets to share?

I'd be interested to know if anyone has ever had this situation occur and a problem resulted.






ps; not sure if JB4135 is taking the piss or he is just completely biased :-p

Using Platinum E90. It's 118 Octane and a blend of ethenol and alcoho-pop, I mean Alcohol. N54 seems too love it. burns quick, clean and keeps oil temp down a touch also.

Yet to dyno with race gas.

It's a myth

Seams JB4 just popped it's first motor.

Response from the tuner was to change the specs from a light weight race gas map to '100oct' needed to run the map in the instruction on his web site. Great customer service IMHO

E90post is filling up with the usual fan boy crap from both sides. Hopefully the OP will post the actual failure cause/results and not get scared off like Sevek.

Why do you find the need to defend your bias? We aren't knocking the product, I'm sure it's good. What we are saying is that both are good!

Someones asking for mod advise, should they not know all the ins and outs?

Personally I'd be more than happy to trial any tune in my car, but only if they are addressing all tuning parameters.

He wasn't running failsafe with his meth setup.Big mistake. Could happen to the best of us. Nothing to do with the JB4.

I have neither tune in my car so I've got no bias, but from what I read here is that the blown motor was from someone running above a standard tune. It seems to me (from a lot of reading) that unless you fiddle with the tune or run big boost, etc, both tunes are pretty much safe.

The blow up in question appears to be a case of user error.

[BBK]

Can't be user error... the jb has no protection so they all blow sooner or later...

[MikeVictor]

I'm not sure if you read the thread, but from my understanding his map selection was inappropriate for his car.
