Default Starter problems on the dyno

I took the car in to the dyno today to get it tuned(It's getting tuned on a dynojet). Well, all of a sudden the car don't start . We turn the key but nothing happens . I'm thinking vats. Apparently it's the starter ,( I personally don't believe it is). I was at 400rwhp when the starter problems began. We stopped the session and will continue on Monday. One of the guys started to worry me as he told me not to expect anything close to 500rwhp . They also mentioned something about my map sensor not being a 3 bar and not knowing how much boost I was making. I am at 4500ft elevation but not even close to 500rwhp? Should I be disappointed with anything less than 500hp or even close to it?

500 rwhp is average for a stock auto with 10psi or less 2 bar MAP is more than u need will work fine.

You don't need a 3 bar MAP 2 bar will be more then enough for your stock engine and setup.

To put it in perspective I'm running a 2 bar MAP which will read upto 210 KPH I believe and I'm at the edge of it with 15ish psi boost.

There's a sticky in the FI section that I created with boost vs kPa conversion.

So in a nutshell if your running 16 psi or less and have a 2bar MAP your good.

My neighbor's bone stock 04 Coupe/auto with 56k miles had the starter crap out on it as well.. I went over everything trying to diagnose it thinking it had to be anything BUT the starter... Well he towed it to a dealer and they changed the starter and $375 later he was rolling again..

I was shocked the starter went bad with that low mileage and never been touched before....

I believe it now though.

Well, he brought up the 3 bar map topic again. He stated I got 458rwhp 431rwtq .I was not there for the final pulls due to being at work and him telling me that we would continue Monday. He could not tell me how much boost I was making. I've got a mechanical boost on there right now and will go out for a spin in a few . The car feels real strong 3k rpms and up . I will get my dyno graphs by email tomorrow and post them up.

He can't tell you how much boost your making? Why not? What program is he using to tune your ride?

See if you can get him to email you the data logs he got while tuning along with a configuration file that he's using.

It did turn out to be the starter . Of all places for it to crap out . I guess I can live with 460 rwhp . What has me stumped is he recommended I put in that turbo 108 additive to the fuel

HP Tuners according to the paperwork I got. It was not a good experience for me being new to FI . I felt a little lost and the tuner did nothing to help me understand in any way.

I gotta be straight with ya. Your tuner saying hey get a 3 bar MAP and also saying that he don't know how much boost your making would make me pick a different tuner. I'm not even a tuner and I know enough on how to calculate boost via a MAP sensor. I also know that unless your making over 15-16 psi a 3bar isn't needed. When you step up to a 3 bar MAP, you loose a bit of resolution. Obviously you have no real choice when making over 210 kPa. Which is about 16 psi boost.

I agree on choosing another tuner , unfortunately there are none in my area. I will need to travel for the next tune. I am left wondering if my tune is locked with Hp tuners "license" having been purchased and if that is going to present a problem when I try to get it retuned.

Brotha your in Texas. Not only was it the only state to be its own country but you have some of the greates LSX tuners in the world who reside in the great state of Texas. Only two states I can think of maybe 3 where there is more then just a few fast vettes. Texas, California and the other state which is NJ.

Do yourself a favor and pm blownbluezo6.
