The OP is obviously an idiot, but the dyno operator should know better, yet he did consecutive pulls on a boosted setup with AFRs in the 15's.
If this hadnt been such a weak sauce JRSC setup it would have blown up pretty quickly.

This is not an isolated incident, I personally know people who operate dynos in my area and most of them are back-yard mechanics at best and have no business anywhere near a dyno or tuning software.


But w/e, if you wnat to put your car in the hands of someone who is likely an idiot, than knock yourself out.

When you get your car dyno'ed you are putting it in the hands of the operator, and it his responsibility to abort the pull if it goes lean, detonates, overheats, etc. since you cant monitor it yourself.

If i were the dyno operator I would have aborted immediately, and upon finding out that the owner hadnt installed any EMS I would have told him to go home and come back when the car was running right.
or better yet I would have advised him to sell the car immediately, buy something bone stock and leave it that way.

If you really think that a dyno perfectly simulates real world load then you my friend are a serious moron.
For one, it seems like dynojets are the most common chassis dynos around, and they put dramatically less load on the engine than driving does, you can actually see substantial difference in spool times. You could tune a car to make all sorts of power on a dynojet, stick it on the road and it will blow the **** up.

I never said that the dyno was useless. Its a very good tool. But the simple fact is that the vast majority of tuners and dyno operators dont know ****. I would rather be safe than sorry and know that when they start dyno tuning my car its already got a good street tune on it.

But thats just me. I guess if I were like you and had to hire a tuner due to my own incompetence then maybe I would fee differently.

A proper dyno tune out does a road tune any day. My tuner scraps EVERYTHING he hasn't done and does it all on the dyno. No blown engines so far... And they get tracked.

The post-dyno road tune should be tweaking and fine tuning only.

All true. Crank, warmup, idle, etc. is all tuned off dyno. You want that sorted before you hit it. But maximum load is on the dyno, not on the street.
