guys who use that dyno who own cobalts keep saying that they have a hard time getting a tach signal so it reads stupid low or something. Like guys who dyno 480 on one will dyno like 320 on that one. So idk I'll have to ask them and find out for sure. The other place finally emailed so I'll see if I dont go there instead

 

Interesting. When I dyno'd there was no direct tach signal he just had me try and hold a constant RPM on the dyno to calibrate the machine. I had a hard time holding it steady and I am betting that is where things went wrong.

 

well I talked to the guy and he said because it was dyno day its all kinda rushed so that could have been why there were problems. Really no time to get it right if something doesnt work

 

Light glare screwing up pic but I couldn't get better shot. All sealed up. Just gotta install

 

Wait, you talked to the guy who did my dyno?

Btw, lights look awesome.

 

I talked to guy at the dyno place that has tach issues . idk who ur guy is

 

You just described my situation perfectly though with it being dyno-day and not having enough time to look into it lol because that is exactly what my guy told me. I was like how the hell did you track him down.

 

 

Yep, that's what happened to me on the first pull when I dynod the first time. We found the right wire though and were good from there.

 

For mine it was reading half rpm and disnt even produce a torque figure

 

Horsepower was bang on it just showed it at the wrong rpm range.

 

well then I guess ill go there after all. we got time to find the correct wire.

 

Tom- we just partially untaped one of the coil wires and used that. Worked fine.

 

To bad its not like the sunfires. They had a rpm signal at one of the fuse box terminals

 

Does speed factor dyno read stupid low tq or what? 353 wheel tq. That dont seem right

 

You have way more than that

 

ya I think so. ill goto other dyno next time

 

 

It's not reading/converting torque correctly on that sheet. Your hp never slows down, bet that thing pulls hard.

 

I agree. I ran my log through virtual dyno and my tq was like 525. Not that that program is at all accurate lol

 

 

ya I will for comparison . u had low tq numbers as well on this turbo right?

 

 

man got a good scare today. driving home and my car looses power and just shut off. oil light goes on...which freaked me out but didn't realize car had shut down. so I look under the car and I thought I saw dripping..checked oil level. nothing on there. called my dad to tow me home . looked under, nothing. no oil, no wet spot nothing at all. so I go to drain it, I was missing about a liter of oil, which id expect with this build and the 100+ hard pulls iv done already in the last 3 months. time to change oil anyway. so I put oil back in to do some tests until I can get new stuff. car would crank but no start. checked codes. fuel injector codes. cleared them....nothing. checked ground, nothing. pumped the gas and it fired for a sec then just cranked again. so I pulled the injector plug, pushed it in as hard as I could so it felt nice and snug, cleared codes again....now I had a fuel pressure code as well, and she started up. relief. guess the injector harness wasn't clicked in and slowly came loose. my trims and idle seem to be a lot better now as well.....will check some more after I do oil change.

 

I've had that happen to my car where it just shuts off and the oil light comes up it's weird because in just driving normally
