Wide band or Narrow band Auto tune?

Impressive for an auto tune

but give us a look at the AFR line at WOT

with wide band sensors, plenty of oportunity and the sensors in a good spot you would expect it to be close.

Ihave had a similar result with the TTS and narrow band sensors it to a bit or work and some long straight road with the throttle buttoned up on some pilbara roads, the AFR line at WOT was as close as fuck is to swearing, Deano at Thundertech did'nt want to waste my money

Thanks guys,

I will be keen to see the dyno results of the 106 Hilly. Keith does awesome work. Hallam Boyz have also worked on the heads(drilled comp releases) and jugs(honed them because my next door neighbour sanded them) and he said the kit was gorgeous, better quality than what Harley put out he said. One thing with Keith though, he plays it safe with the squish so I took a whisker more off the cylinders to bring it back to 0.030.

Pauly, I didn't upgrade the tuner. The PC V has been my tuner of choice on all 4 cruisers Ive had. All I did was purchase the Autotune module from M & M Cycles and it comes with 2 wide band sensors.

I sold the engine with the sanded jugs to a mate and the bike purrrrrs, so that actualy wasnt a bad idea, when Hallam Boyz seen those jugs I sanded back then he even said they would wear in new rings just fine and he was right, the bike is doing really well. Because its a mate, if anything does go wrong, I will help him install a Dunnperformance 103 kit to make up for it but I think the engine is going to be reliable, time will tell.

I would love to now the HP and TQ numbers from 3 engines that all used the same cams, TB, Air, pipes ect;

Keith Dunn 103 kit
S & S 106 kit
and the
Fuel Moto 107 kit

Hi,

Good work bashful, legendary engine builder, one of the finest

Thanks

Ha Ha 

they  are  happy figures , cool should run  11.8 at strip ,  we should organise day  a day at heathcote when weather better for forum play day , cheers

That would be awsome, I have 16 peolple I ride with in Geelong and 5 of us went to Calder to watch and we want to run the strip for fun. I did a test today and trap speed was around 180 clicks so not sure what 1/4 time, i figure the 12s. Held bike at 4000rpm, dropped clutch and back wheel did set me ofcoarse by about 1 meter or more.

the drags good fun , hardest part is leaveing the line , love it , i cant ride for shit but the rush is awsom

Back at the start of this thread I have placed a dyno chart from today showing exhaust comparisons. The results may not be 100% accurate due to the CF setting being different and obviously 2 different dyno's allthough both are dynajet.

I have changed my exhaust from stock headers and s & s slipons to v & h big radius 2 into 2 with stock baffles replaced with BCT baffles, changed the map a little by going 12.5 instead of 13.5 at 100% throttle.

Hi,

Good stuff bashful, you reckon try a 2 to 1 pipe on your build, would be good comparison, well done, legendary job

Great experience to once again highlight these bikes are very very easy to work on

Thanks

to test new changes to bike , allways better to use same machine to monitor , tyre presure changes of from 28 psi to 38 psi will change readings 3 hp , then conditions humidity etc will have small effect also and  quality of air , i have had bike here with tyre pressure at 18  psi , pumped up to 38 psi and bike which is 95 cuber jumped from low 90's to 105 rwhp , i also made this hp with 1.800 valves size in head , robots maybe right , they are very simple to make go

Funny how the fist sheet does 100ftlbs at 2500rpm and the second sheet does 100ftlbs at 3500rpm

hi ando , different pipes or restrictions will move torque miles , to open up pipes generally shifts peak torque higher in rev range , these engs are very exhaust sensitve ,thats were important to use same machine for monitering changes .

hi,

when i do mine i going take to same dyno operator each time, professional

thanks
