Well, ****. More crank sensor problems!
I've been doing alot of work on the car. We went over to a local mustang dyno to do some pulls, and hopefully get the car fully tuned this evening.
Starting out, adjusting some fuel maps got everything running much more smoothly all over, transitioning started to sound much cleaner.
At around 5500 RPM, we were loosing crank signal all of a sudden. Watching the Miss counter, discrepancies between cam and crank sensor, we could see that as we adjusted sensor voltage at each rpm range, the amount of hits would vary. Go too high, lots of misses, go to low, lose pickup completely.
Apparently most ecu's have this garbage configured for common sensors. Haltech wants you to use an ocilloscope to figure out the voltage at each rpm. My tuner is going to be talking to the Haltech people again tomorrow. This is kinda bull****, serious waste of dyno time....$.
On the bright side, the motor sounds really healthy. I love the sound. This particular Mustang dyno is affectionately called the heartbreaker. I'm not as concerned with the dyno number as the MPH, so i don't really care. But, we never put any timing to it, but it made 121ftlbs at ~3k one one pull. At ~5k, it made 103whp, again with no timing.
Just to reiterate what's on this motor at this point.
-Stock OBD1 block
-Ported obd1 stock valve head, decked .060" for 11:1 compression
-276 cam
-Short runner intake
-1.75" 4-1 header with a 2.25 TT catback
-19lb injectors, CIS fuel pump
-stock obd2 throttle body
-stock 8v flywheel and clutch
-2h 3.94 trans
-Sequential injection on Haltech
Dirty ****ing car.

Scored a New/used TT 298 cam in the classifieds. As i've vowed to buy as many things used as i can, i had to pull the trigger.
Down the road, after springs, rod bolts, and lifter bore clearancing, we'll see what stock valves will do with that cam.![]()

I drove the car around a bit today.
Washed it, and installed the most bitchin hoodpins ever.

Love the hood pins!

Minimalistic, I like.
Personally I prefer the AeroCatch hood latches myself.

I didn't like aero catches on my mk3 hood, and they really didn't seem to fit this car aesthetically. These are like half the price as well.

She mean muggin.
Yea, and i can't wait to get the 3.68 trans into this thing. This rolling diameter with the 3.94 is a little much. I feel like i'm in 5th at 35mph.
#224
Decided to stop keeping the car at the shop
My 298 came in. Wahhh, can't run it just yet.
I got my rear wheels cleaned up, sand blasted, and balanced tonight. No pics yet, but they look alot better.

So, we've been working hard trying to get this car sorted.
All of this might have been a cam sensor issue after all.
Right now, we have it running batch fire, and it revs all the way out with very few misses.
Parking lot, open diff burnout drifting is too much fun, and the car feels pretty damn quick even with 20 deg of timing.
I'm excited.....
Still sorting drivability stuff whenever i get the chance to poke at it. I need to finish wiring gauges, and finish redoing the lighting harnesses.
Perhaps tomorrow!
Also, looking at my finances, i think i can get everything on it to dyno with a 100 shot on the 276 cam. I'm going to decide on the 298, and combine it with a few other engine bits when that goes in.
#227
Getting on the Dyno tomorrow. Not an absolute hell hole this time.
My crank issues have straightened out in batch fire. The car feels really quick even making the uninspiring amount of power it's making right now. I still have a cam sensor issue if i try to run sequential, but honestly i'm done ****ing with it for awhile. I just want to beat it up.
I'll do me best for pics/video!

Dyno aborted the morning of. Intermittant crank signal misses even with the same settings in the ecu, day to day. I can usually straighten it out after the car warms up and with a few voltage threshold adjustments, but misses like this are a problem. Especially if i ever want to put a bottle on the car.
Finishing a few things this afternoon, and leaving it with my tuner tomorrow. First time i think i've ever left a car of mine with somebody.
Got pulled over twice in the past 3 days by the way, lol. The whole no bumper thing grabs too much police attention.
#232
I dropped the car at my tuner's shop. First time i've ever left a car somewhere to be worked on by anybody other than me. Liberating.
Hopefully he can figure this junk out this week.
Tech flexed all the wire, headlight to tail light. Lighting harnesses are from scratch. Just finishing up organizing and finalizing under the dash.
Dash is getting there, gauge/switch harness is done.

Where is your speed-o-meter? How do you know when to hit the NOS?
GOOGLE IS YOUR FRIEND.
I like grocery getters.
#235
No speedo.
I'll have the ecu setup to ground the relay to the nitrous solenoid when:
-rpm's are in the correct range
-tps is >90%
-Manifold pressure is in the correct range
-Coolant temp is in the correct range
And more importantly, to shut it off if any of these values go out of their acceptable ranges.
So hopefully, burnout, flip the switch, and just make a pass otherwise normally.
#236
Woke up this morning to a text saying my crank issues are resolved. No details yet.
He wants to try a different coil as there are still a few misses underload, but nothing like what we had. So, we're moving along.![]()

New BERU coil, and bkr5e's installed. Not sure how i even got my hands on them, but i had some odd bosch joints in there. Now i wait to hear back again.
Too excited. It's running in sequential again, and should be an absolute ball by the weekend.

I'm having a really hard time deciding what it'll do on the motor!
I'm still not used to 4 cylinders. The vr was just BAAAAAAAAAAAAH all the time. This is wwwwwwwaaaaaaAAAAAAAAAAHHHHHHHHHHHHH!

Slap a vr in front and throw this one in the back!
Just kidding, keep it up!
