I would just go to another dyno. You were probably told the bhp at crank and not whp. |
Hmm... I thought the COBB could just flash over the ECU anytime, could anyone with more experience chime in on this? The AP should be able to overwrite whatever is currently on the ECU shouldn't it?[/QUOTE] i over wrote my piasini tune when i got my AP and have probably done 20-30 re flashes since then getting me e85 and 93 maps dialed in, so no lingering issues. |

In for AP/Dyno results! |
Just sent another PM to @eric@edgeautosport so we can get the AP ordered. Results posted in a week or so... not sure how long it's gonna take me and @rfinkle2 to get everything dialed in. |

2 Attachment(s) Ok... so I got the AP today... got my MAF calibrated, got some logs, and sent them over to @rfinkle2 Initial impressions... power does not come on as quick as I'm used to... I don't get that "kick" in 2nd and 3rd that I'm used to. I think this can be fixed by bringing boost on earlier and playing with the throttle. That being said, after a single revision by Rob, the virtual dyno shows 307 WHP and 369 Torque. Not bad at all for a first revision. There's still some kinks to work out, I need to up boost more, and there is some fine tuning to be made. I bet we can pull another 20 WHP out of this tune by upping the boost back to 22 PSI like I'm used to, playing with timing, and leaning it out a little more. Maybe Joe's tune is not the unicorn dust, maybe it's my car. I bet after me and @rfinkle2 work on this tune over the next week we can make some good numbers. I'm quite impressed with 307 WHP after the first revision. Log, and Virtual Dyno below: |
All that work in one day? Impressive! It took me a week just to calibrate my maf. tapaduh |
Mag cal was easy as pie after reading the how to in the ecu tuning sticky. Had 0 on all my ltft within 20 mins. |
just curious why you didn't log the map you had before to compare VD graphs?? |
Drenkel, if you have an old log (fom your Piasani tune), it would be great to input into VD so we can compare numbers. I don't need the log itself if you'd like to create the VD plot. Is your car one of these cars? http://dptune.com/dpt_016.htm |

so cal maf...drive 50 miles..run maf cal logs...make changes...drive 50 miles...rinse repeat. you can speed up the process by driving with MAF vt displayed and hold your engine RPM at the various voltages to get them filled in faster. and zero LTFT is near impossible. |

exactly! using my method greatly reduces the miles required to fill in LTFT. get on the interstate with the AP showing MAF vt. Cruise around in different gears and different RPM while holding the voltage at various locations will fill in LTFT very quickly. walk your way up the vt range holding about every .5 to maybe .25 for a few seconds [20 maybe] and volia' your LFTF for that voltage is active. it will still change a lil more over time but I call this a "rapid prototyping" kind of maf cal for part throttle :) I completely ignore STFT for calibration purposes...just too volatile. I will "look" at it to see if its climbing and then maybe at a % or so to the LTFT for that range but wouldn't add/subtract the entire STFT from LTFT. |
Ya after putting miles on the car I'm seeing ltft as much as +2 in some areas, gonna have to calibrate it again. I tried the vdyno with Piasini logs and it said like 640 WHP lol. The dashdaq spits out multiple rows of info for the same time stamp, vdyno really doesn't like that as the numbers in some rows don't match on the same time stamp. It's really cluttered. The way the AP logs is much easier to read. When I married my AP though, it DID save my Piasini tune. When we finally get this map worked out I'll be able to unmarry the AP and do a dyno run with the Piasini tune on the same day on the same dyno. The guy at Cobb in Austin looked at this for me and did confirm unmarrying the AP would restore the Piasini data. |
nah...+- 2 is done IMO. any closeer and you'll just chase your tail as seasons change and you fill up at different gas stations...air filter gets dirty..etc. I do tend to prefer a negative LTFT which puts you on the richer side at OL transition but that greatly depends on when you transition to OL and at what Maf voltage that is, and what the LTFT is at that breakpoint. see chasing tails :) |
Unfortunately it's rainy here today. I got a new revision to try out, but I'm not gonna be able to get some good pulls till it dries up. Gonna drive around and check out throttle response and boost tho, and do another maf cal. |
For quick MAF cals, use the WOT section of the previous map and scale as needed. Or, log some low load LTFTs which can fill in quickly and again scale. Then use WOT to tell you how far you are off. You do need to be careful going WOT, but if the MAF housing is well designed it should be smooth in response and you should only need to use a global multiplier so WOT/OL is a good place to see if the cal is off. |

^^^ Read the whole thread before posting man, your clueless to what's going on |
@rfinkle2 Testing out your version 2 revision now... the throttle definitely has an "OH SHIT" position now, about 3/4 the way down it really punches hard. Feels like it's making more power than the first revision, but that could just be the "OH SHIT" punch tricking me lol. Part throttle driving feels like driving a N/A engine. I'm used to boosting part throttle, so the car feels slower in this aspect. I don't really build any boost at all until the pedal is pressed down a good amount. My previous tune would start to build boost at 1/4 throttle. It's like driving a completely different car. I'm reserving opinion on the throttle response for now, it is smoother for regular stop and go driving, which I like, it just does not feel very peppy. But on the other hand, when I do mash the petal all the way to the floor I get the "OH SHIT" factor and a big grin on my face. I'm going to drive on it for a bit before I make a decision on changing the throttle response. The roads are drying up now, I'm gonna go put a few more miles on the car and then get you some new logs on your 2nd revision. My dashdaq monitor shows everything as A-OK on the sensors, so it seems pretty safe to do some pulls. Will post up results later tonight. |
shitty pissany tune was probably using the OE throttle mapping which is very aggressive and the Cobb maps are very linear. fink can crank that back up if you like it that way but IMO it makes it harder to control wheelspin. |

2 Attachment(s) Did some more driving, only had a chance to get in 1 pull due to traffic... gonna get more logs tonight after work when no-one is on the road for the 3rd revision, but looks great so far! After 2nd revision I'm at 324 WHP and 380 Torque Attaching Vdyno and log. Want to give mad props to Rob, after only 2 revisions the car is doing awesome. He's a great guy to work with, and I can't wait to see what the final numbers are. We still need to lean it out a little more, increase boost to 22 PSI and play with timing. I bet my car hits the numbers I originally posted (If not higher) with the AP tune. Proof is in the pudding, and it looks like Joe's tune isnt the magic unicorn dust, it's my car. Is it possible that my custom straight pipe has opened up enough flow to achieve the extra power, or is my car just a factory freak? I truly believe me and @rfinkle2 will hit close to 350 WHP and 400 Torque when the AP tune is finished. |
Quote:
No. Rob is AWESOME, I am NOT doubting his abilities 1 bit. You will not reach 350whp. You CAN break 400 ft/lb. As I have said before, the turbo is in the way. |
324hp? on a bump or wheelspin? meh. not consistent. |
You hit a bump in the road and have smoothing set to 1. *edit and zooming in its a 3rd gear log.......... |
No bumps, was a new, flat road. Repaved like 3 months ago. Let's hold judgement till the tune is finished and I get it on a real dyno :) If the real dyno shows 340-350 WHP are you still gonna doubt? The whole purpose of this test is to provide proof, I'm doing all I can here. There's still 3 areas we havent played with yet to ring some extra HP out. 2 more PSI of boost, leaner AFR's, and a little timing advance. I believe we are gonna do it, and when I post the real dyno sheet your just gonna have to accept that my car is a unicorn :drive: |

Add your timing and boost in any you will be at ~300whp just like every other k04 car out there.* *That isn't running excess oxygen in their fuel (E85) or in their air (Nitrous---->bucker) |

Look back one year ago, if anyone were to tell you that a 700 WHP MZR Speed 3 could exists would you of said "hell yea" or just laughed at them. I know I would of laughed at them, but look... we have a 700 WHP unicorn now, LOL. |
Quote:
I got $100 bucks that says if I get a legit dyno that shows 340 WHP Ziggo would still find something wrong with it. Any takers? I have confidence I'll hit that number, and have a dyno to prove it. I also have confidence that Ziggo, and at least 2 others will call liar liar. Just because you diddnt do it don't mean it can't happen. |
Take everything else out and look at any VD graph. Any jumps in HP are not real. Please take logs in 4th gear like everyone else and set the smoothing to 2 or 3 and we can see where you are really at. Take a look at the battle v dyno thread and you can see examples of stable graphing. Tappin |
