Re: Mark's 1G Winter Projects
A point is almost 9% difference, I doubt your injectors have that much variance, but maybe that combined with airflow differences per cylinder I suppose it could happen.
Maybe the widebands are reading wrong, it might be easier to swap what cylinders the widebands are on to see if the readings follow the sensor.
Good luck this weekend!

Re: Mark's 1G Winter Projects
So is your plan to try to tune it with the downpipe wideband then use single cylinder widebands for fine tuning?
Boost by speed should be sweet!

Re: Mark's 1G Winter Projects
Progress is good! I hear ya on the cam/crank signals, I've been battling them on my car for quite awhile. Signal overlap combined with noise on the line gets frustrating. Mines still just a VR sensor setup running in a 24-1 configuration, what's your new setup?

Yeah its hard to believe it, swapping around the O2's and injectors will build confidance. Swap the most lean cylinder with most rich type of thing.

You're correct, I'm using the DP sensor to tune with, and in the future cylinder trims can be adjusted with the individual cylinder sensors.

I know! I'm just going to try to get some passes in, racing is scondary.

The new setup is a Kiggley 12 tooth wheel on the crank for engine position, it's a hall effect sensor. Then the OEM optical cam sensor for compression stroke. I verified that the signal looks great on an oscilloscope, very minimal noise present.

Re: Mark's 1G Winter Projects
there are settings in the AEM to compensate for timing drift with a hall effect sensor vs cam/crank pickup, the main issue is the factory 1g cam sensor has to deal with timing belt slop and the hall effect sensor with the speed of light being slow....
With the 2g dsm/evo cam/crank pick ups are mag pick ups, so nice square wave triggers. Using the kiggly crank trigger, square wave, and the dsm cam signal hall effect could be an issue with the EMS that needs be figured out.
I know if you run the 1g hall effect you use a different timing and drift offset vs the 2g/evo cam and crank trigger setups.
so it may be a thing of using the factory dsm cam trigger drift offset, and the 2g crank trigger offset values in the EMS.
The only other thing I can think off is you said the timing numbers were spot on, I know with my car being waist spark and a black top cas, I put the timing light on the #4 cylinder and when we sync timing it does not go over 10deg(the timing #we set to look for) at idle or at 7,000+rpm I would estimate it jumps around at least 1deg, and I make sure it does not go over our target number. so at 10,000rpm and 45psi I know the number on the map is no more then indicated.
That would be the lure of a solid, no mater what timing number, if the car could use 1 more deg, but not 1.25 you can make that change and be sure its correct.

Re: Mark's 1G Winter Projects
A little update, the car is awesome with the dog box! Shifting is the best, the only issue now is launching it with the tall first gear. The clutch is hard to figure out at this point, it took three passes to get some serious power to the ground off the line, then in second gear my rear end broke That pass was a 1.37 60'!!!!! No parts shot out but I can spin one tire at a time in the rear!
The first pass off of the trailer I tried to launch and just about killed the car, ran a 2.3 60 foot then ran the car out and hit 165MPH at the traps on a 10.3 second pass! It weighted 2420 on the BIR scale with full exhaust on it, carpet, door panels, passender seat and harness, with all of my safety gear in it. This winter paid off in the weight savings department.
I have a rear end with me so I'm going to swap it out and try again tomorrow. Does anyone have any 4 bolt lsd rearends? I need to get another back up.

Awesome trap, hopefully you can pair that bad ass 60ft with that trap

Re: Mark's 1G Winter Projects
weren't we going for like 158 last year?
Damn dude. Good luck, 1.37 60ft is no joke esp. in a manual DSM.

Re: Mark's 1G Winter Projects
Nice work! I say it will be somewhere in high 8s with a successful pass.

Re: Mark's 1G Winter Projects
What did the car weigh last year? 165 mph is moving in the quarter. Hope you get a clean pass out of it tomorrow.

Re: Mark's 1G Winter Projects
I have 3 extra 3bolt rear ends, I swap the 4 bolt carrier in and use the 3 bolt ring/pinion.

Re: Mark's 1G Winter Projects
Wow! Couple that killer 60' with that trap and you will put up some killer numbers! Good luck tomorrow.

Re: Mark's 1G Winter Projects
I was hoping to see the car run today but just saw it on the trailer. Did something break again?

Re: Mark's 1G Winter Projects
I replaced the rear end, drove the car around and all was good. I noticed a cracked weld in my intercooler piping. More than likely due to my messed up launch the first two passes. The car bounced very hard. I could not find a tig welder on site, so I shut racing down for the weekend and enjoyed the event.
The car will be ready for the MAP event, easy fix! Like I said before in three passes I went faster, and cut my best 60 foot ever! It was a very successful weekend even though I didn't put it all together for an epic pass. I know it will happen soon!!!
There was a crazy N/A powered (No nos) '68 pro-outlaw Camaro out there with a Fuel Injected Sonny's 892CI that ran a 6.44 at 210+! Wild car, I looked up the engine and it makes something like 2200HP - N/A. Also there were some crazy twin turbo firebirds and mustangs. I had a great weekend!
