$900+ for a tune sounds way to high with MS. I know when I had Jerry @ DIYAutoTune tune my car 2 years ago I paid about 400$ for my tune. I figure when my built motor is running correctly it will be a little more then that to get re-tuned, but that will be because I am going for a good bit more power and have a more complicated setup.

Let me know when DIY does GTR. |
lol @ the haters :D
|
RESULTS ARE IN with said setup... keep in mind its a MUSTANG dyno blahhhh
213 whp 191 tq torque is a table top from 3400 rpm to redline 12.5 psi reached by 3400 rpm 1.5 hours = $352.50 :) :) :) |
Nice numbers, did AMS change their dyno? It was a dynojet before.

Didn't take them long, thats for sure.
Did they tell you what was holding you back from making higher numbers??? |
as far as the dyno, it said mustang dyno on it... they have a new location in west chicago, moved from arlington heights.
as for detonation, i told him to put it at a safe DD tune, so he did and said he has no worries... he also said it was a clean pull the whole time and ran well. but he did say if i am ever on a road course to put like 100 octane gas in there... but i wont be on a road course.... FOR A WHILE :) |
That's what I was waiting for. Not too shabby. Time wise and price wise, that sounds pretty reasonable. Congrats!
Now HKSturboMiata needs to post his numbers so we can see what that silly GT30 does. |

I'd still like to know their interpretation of "safe" in terms of retard from MBT.

goofy shitty quality vid
|
thanks shane! yeah bad quality but a video nonetheless... wow it jumps passed 60mph so quickly even when rolling onto boost in 3rd at 3000rpm! so much better than stock.
|
I am curious what is done in a tuning session. Several dyno runs. Data log then VE analyze? Do they run a WB O2 in the tailpipe? It would be sweet to take video of the process.

Most of the time "tuners" shove the WB in the tail pipe, post cat, and guess how effective the cat converter is. I wouldn't dare do this on a track car with a cat. |

umm you could run a little more timing in the cells you would be in while "hanging @ 6k in 6th" (which would be high rpm/ med. load) compared to wot. if by "hanging" you mean holding it at 6k, it doesn't seem like you would need wot. but i usually don't cruise at that speed, so i'm not positive. i know i can cruise 4th (which is like your 5th) at 6k with approx. 50-60% throttle Most of the time "tuners" shove the WB in the tail pipe, post cat, and guess how effective the cat converter is. I wouldn't dare do this on a track car with a cat. not trying to bust your balls, but i hate mis-information on the net, and especially on forums i like. also it's pretty ridiculous to assume that because you tuned your own personal car, (only 1 car at that) that it's easy. |

If I had a proper trigger wheel I'd put 3* of spark back into it. I don't trust the timing belt, the 2-tooth wheel, nor the heat-soak. I've also checked AFR on 3-dynos and determined from the Exatorq/Mustang dyno that my LC-1 is .1 leaner than reality when measured from the calibration gas. When compared to the LC-1, there was a .4 difference on the DD in Austin, no difference on the Exatorq Mustang in Garland, and 1.5 difference from BEGi's dyno (at the San Marcos shop) to reality. I don't think tuning is "easy", nor do I think I'm an anywhere near an expert, but I affirm that tuning fuel and spark is not a black-art or mystery. Its a straightforward set of rules and allowances for the shortcomings of MS and the Miata electronics. I've tuned 4-total FI cars as favors for friends and they're all still running. |
watching chris tune my car was pretty interesting. he does these weird routines with the throttle at different rpm, makes a change, then does some other rhythmic routine... its not til later do the redline pulls happen... you can really tell its his day job lol

So care to post a dyno plot and a spark table?
i gotta scan the dyno chart, tried to photograph it... epic FAIL |
