new tuner is required

 

ii think the 30 degrees was his base timing.

what we want to know is what is the ign timing you have on your WOT.

with 91-93 octane, whats your IAT? did you do plug readings on the other cylinders after the BOOM?

you should only be hitting 300hp or so with 93 octane. 400 is a bit pushing it.

 

maybe around 330hp with 93

 

Who was your tuner so when I come back home to FL I know to avoid him.

 

Tell you what.... I am still a mod over on the Neptune forums. You can post your file there or you can email it to me so I can take a look at it. If you want to email the cal file send it to: tepid1@sbcglobal.net

 

How much is recommended on 91oct

 

yeah i want to kno who your tuner was so i can avoid them

 

where in fl do you live i live in ft myers

 

timing was 30 degrees at idle and he said he had it at 21 degrees on his lap top by the way i'm running hondata s200.

 

i'm gonna have the injectors flow tested just to make sure they ok thats what the tuner wants me to do

 

i'm not gonna disclose his name and the name of his shop until i'm possitive it was his fault

 

my car was pushing 320whp at 14 psi but yesterday when it blew up it was running 12psi

 

im gonna try to get the file and email to you i jsut hope he didnt change anything

 

That sucks dude. Its too bad that there is a no-fault policy for tuners when at times, not that this is definitively one of those times, it IS their fault.

 

detonation homie, too much timing or **** fuel, pre ignite will go after the center of the piston

 

30 degree's at idle?? what in the hell?

 

Don't waste your time and money flow testing the injectors, if that were the cause, you would have only one piston damaged. If by some miracle all 4 injectors were not flowing properly, then the tuner obviously would have noticed improper AFR...

...and by the way, don't be scared to say who tuned the car. There is nothing wrong with saying who tuned the car, whether or not he is the cause of the failure. It would be wrong to say "so and so" blew my motor, yes, but until you are certain of that, there is no harm in saying who did the work for you... You did after all pay him for a service.

Just think, right now there could be a person getting his pride and joy tuned by this same person tomorrow, he may have seen this thread, and won't be informed of a possible issue with the guy. Look at it this way, you would want to be informed wouldn't you?

 

plus there is a ton more reasons why it could have detonated NOT being the "tuners fault" (well he should have noticed before he proceeded.)

what did the batt voltage look like when it melted down? what fuel pump is on the car?what injectors? what was the coolent temp? what was the total timing at the boost level u were runnning? was the any comps tables active when it melted down?

was the motor syned with the ECU? is there a stock distributer on this car? what ecu? i think i heard neptune?

there is soooooo many things that could have happened here....

 

not too uncommom with a big injector car, nor with a exotic fuel either... but pump gas ? a little extremeIMO

 

i guess your right the name of the shop is tuning tricks in ft myers florida an the tuners name is Todd

 

i dont know if it matters but the car ran 10 AFR on WOT a few times when he was tuning it

 

30 degrees on pump gas...


That guy just stole your money, and slapped you in the face, and then put salt and alchahol on your wounds

 

I use to run high timing at idle too.... for many reasons. Never had this problem though....

 

[quote=I CRX I;41688068]it may have been 30* at MBT, not base timing.[/quote

A MBT of 30 deg on pump gas @1 bar, would do very quickly what it did in those pic

 

AFR dont mean **** if there is too much timing, throw in as much fuel as you want ull still end up with ur motor at the end of the day
