It doesn't matter at this point whether he was shifting with wheel pedals or stick. It's too much of a difference for him to keep up or catch up. The minimal milliseconds between shifters wont' make up for it IMO.

BTW, the Procede car did have catless DPs and an exhaust with HFCs.

Yeah, I would join in with tune only. So hopefully a tune only GIAC can come along. I seriously lost some HP since the progman update. But can still run 12.7 @ 112 mph with a second gear launch (0-60 4.2 seconds) on 91 octane and map #7. I never run the lower maps.
FYI: I know these are roll ons, but my last time out, my quickest times were 2nd gear launches! This tune does have some decent low end torque, LOL.

You mean "lose" unless you're referring to Paris Hilton. Great race. JB3 1.4 is definitely a beast once it gets going. Imagine a home flasher with JB3 1.4 tune with switchable maps in the future.

Not sure why the results of the PROcede car is a surprise to anybody really.
When I did the first PROcede V3 vs JB3 dyno back to back on the same car, same day, same dyno the JB3 came out ahead. When I organized the West Coast dyno day in which 20 people with both PROcede and JB3 tuned cars came out, often making more power with less mods too. Whenever we've gotten together for runs in Mexico the JB3 cars pull on the PROcede cars. Last time I pulled on Mote when he had his PROcede in and full mods on race gas. I was on JB3 Map 7 and 93 Octane only. I'd still creep away on him. A couple days later he dynoed his car and was a bit upset by the power results. He then put in a JB3 and redynoed and got like 20 rwhp more but still lower than what he should of. Then he put in new plugs and picked up another 25 rwhp. But even on the bad plugs the JB3 once again posted like 20 rwhp more. As for the reason Mr. 5 would get the jump each time. Two reasons: 1. He's doing the honking I'd suspect and that gives him a few milliseconds advantage, as the other cars have to wait to hear the horn then react where as the person honking knows when he's hitting the 3rd honk and can react quicker. 2. And more importantly, I've posted about this a few times in the past too. The manual cars ALWAYS jump ahead of the autos in rolling runs. I've run STOCK manual cars against my auto 335i when it was stock, and EVERYTIME the manuals would pull ahead right after the honk by .25-.5 CLs I think it's that the autos tranny just has a tiny bit more lag programed in. I'd say the GIAC Stage 1 is probably close to JB3 1.4 Map 5 but maybe a tiny bit less still. Auto tranny's seem to have a 1-1.25 CL advantage in 40-120+ runs (they always drop back 1/2 CL at first but then end up being .5-.75 CL's in front....all mods equal). But even on Map 5 the JB3 car seemed to pull away quicker and more than 1 CL as it went out of view on the first run and was going out of view on the second run when he hit the brakes. So clearly even on Map 5 the JB3 car was pulling more than the 1-1.25 CL's an auto tranny's advantage is over a manuals. And that's with a heavier car. The mods seemed close, but Mr. 5 also has HFC exhaust. His car is already lighter being a manual and aftermarket exhaust's usually drop another 25-30+ lbs. So again, I'd say the GIAC Stage 1 tune is close to JB3 Map 5, but still a bit less. Probably somewhere in the middle between Map 3 and Map 5 Too bad you guys didn't do a JB3 Map 3 run. My guess is it would of been close but Mr. 5 might of edged the Map 3 out by .5-.75 CL's The only way to really know is to get a tune only JB3 1.4 335i with auto tranny on Map 5 and run against a tune only GIAC Stage 1 335i with auto tranny. This way there is no driver shifting excuses or anything. My guess is the JB3 car will ever so slightly creep. Maybe ending up .5 CL's ahead from 40-120. Map 7 JB3 is about 15-18 rwhp more powerful than Map 5 if you have the correct supporting mods. But on an otherwise stock car on 91 Octane, it's only about 7-8 rwhp more peak, but often has a dip in the powerband around 5000-5500 rpms due to some timing/knock being pulled for not having proper octane/mods. So in that case Map 7 is only marginally faster than Map 5 As has been said and known for some time (since the JB3 was first released) it's just a very strong tune that the others just can't quite seem to match. Good runs and vids Craig. |

Nice comparison MR. 5.
I have not had any HPFP issues, but the car is stock. I am waiting to see what AMS finds out with their research, then I would like to get the GIAC flash. The comparison was very helpful. I think people need to keep in mind that although the JB3 car was faster, the GIAC tune is most likely a safer and more conservative tune, but still made decent power. Gumpy. |

Don't the DCI's add an extra 10whp or so in ideal conditions such as these high speed runs? I believe your DCI vs stock Intake dyno thread tells this story very clearly. Mr. 5 you are on the stock Intake, correct? I'm not sure how negligible that is on a high speed run but I would think it would account for more top end power for sure. Perhaps if you had one you'd be a lot closer, if not faster (?), than that Map5 run suggests.

Love the comparisons Mr. 5, really is refreshing to know what the different tunes do and how they react on the road rather than on the dyno.

If the GIAC flash was a Cobb or SCT like handheld flash device that all you had to do was plug it into the OBD port and flash the car, or flash back to stock in minutes and was undetectable to the ECU when flashed back to stock, it would be a winner at that price. But without those conveniences and pretty instant warranty voiding (if the ECU registers it had been flashed and you can't clear that with a BT Cable) it's too risky and too much of a problem flashing back and forth from tuned to stock when needed. For those cars out of warranty, it's a nice option though if you don't want to mess with a piggyback and don't mind a bit less power than JB3 offers. Somebody with a JB+ at 75% should run a GIAC Stage 1 flash only car, I'd bet that would be close too. GIAC would probably come out a bit ahead though. |

Wow great runs Craig. Pretty impressed with the results for stage 1 on the GIAC.
I will have my car back tomorrow, if you want to do some runs this coming weekend. AT puts your 6MT at a disadvantage as I've raced numerous AT's to know. I'm 6MT so I think we should match up great. We can do 91 octane and me on map 5 if you'd like. Let me know! Oh and... we can even video tape me filling up with 91 octane for the rest of the forum. |
