88 CI to 98 CI UPGRADE

I like to change my plugs every riding season. I use Champion RN12YC plugs, recommended for shovelheads and the best wires money can buy, also recommended for double fire shovels (one short, one long). I guess everyone has to use what's best for their particular model bike.

Ok, lets get back to the thread topic. I finally downloaded the DTT software that is offered free from their site and I have viewed the tables that it shows me for the MAP that BaggerPaul installed to the module. The following is the graph and the following is the numeric table. I don't understand it 100% yet so I will let BaggerPaul explain what is going on with it.

map sensor vacum tables are shown most vacum created by the motor closed throttle .would be 16 - max map (wot) no vacum throttle wide open . 30 . top to bottom left side of column . right to left self explanation .0-7500 rpm . its not an alpha n input because there is no tps input to the module . so its input to the module is based on manifold pressure and vacum . as vacum is decreased from the intake timing is corrected . as vacum is created timing is corrected . being there is no other input other than the crank position sensor and manifold absolute pressure sensor . tunning is quite tricky so its best to start with a safe map and tune under load on a dyno . there is no feed back as far as temp is concerned . so be carefull when playing with timing on a carb twin cam! p.s. the notes at the bottom of page are defaults and do not pertain to johns map

I do want to say that this MAP was made when the dials on the physical module dials were set at 5 Initial and 5 Advance. Since then, I have backed the Initial timing physically on the module dial down to 4 and I feel that I am running better here. Keep in mind that when the MAP that BP installed, it was only 35* outside, once it warmed up and pressures started changing, an adjustment was called for as pinging was happening.

BP, thoughts??

When you upload a map settings are to be set at 5 5 so you can now change the uploaded settings made to the custom map .and only that map built . To go back to the original 5 5 you must load 5 5

Ohh, you guys make me :witsend: .

Common Man, it isn't that bad.:roflmao:

Today I got the USB interface cables for my ignition. I am ready to rock and roll. Bike goes in on Tuesday morning for the dyno tune. I hope all goes well and I see what I am hoping to see.

No...the pic sure is purdy:roflmao: A loooong way from points and condensors...

Let us know how close you were to the final settings....I'm bettin' it's going in pretty damn close to bang on....

maybe its only the first time ive done this . i had him very convinced that ive done it in the past ! but i hope he did not notice im a novice . i think he will be a tad lean at 5.500 rpm maybe 13.8 but i would leaave it be at that point he will get more mph that way and not hurt a thing im betting he will get one horse per ci out of the first pull no tunning. maybe more

Novice eh, Good one:roflmao:..1 horse/cube is a nice build...

there is more in it then that its up to the tunner.if he whants to set it on kill or not . he should know the powers in the cam and heads and exhaust the piston size dont come in to play all that much it will gain ya torque by cubic inches for sure but its all in the correct combo . and i think he did a great job in picking the correct mix he got alot of good gray beard help off the forum htt and builders .he went kinda conservitive on the cams but they run good i might have to get a set for the dyna till the big motor goes in they rip off the bottom for mouse cams . those red shift 557 run out dam good for what they are . and quiet as hell you cant hear that motor running . if it was not for the exhaust you would think it is off . and for gear drives its quiet !

Good luck on Tuesday - hope your tuner don't party too hardy the day before LOL.

I have to say that I am really looking forward to getting my bike back. I am just really curious as to what kind of power that I am making and how he did with the tune. I am going to go and see him here in just a bit as I want to drop off a jump drive for him so he can put what the final MAP is so I can post for everyone. I will be there in about an hour.

Well, I just got back from MCC and had a sneak peak at what my bike is showing for power. I have to say that I am not happy with what the turn out is at all. Not what I was expecting. I won't have the bike back yet until later today or early tomorrow. Will post sheets then.

let him work it will get better . its all in the tune at this point. good things happen to those who wait!

You are right.... I just felt the Fonz....
