Hustler wakes up my sleepy '94
No exciting turbo or anything, but a MegaSquirt install and tune made a shitload of difference! Last year, johnwag and I did a '99 head/intake swap, but I didn't really see any improvement at the dyno. It was a whopping 108 whp on a Dynojet. I fiddled with the timing, yadda yadda, but it just felt a little sleepy like it was bone stock.
So over the last few weeks, I got a box of old parts from wags (header, intake, MegaSquirt, and some other stuff). They worked long and hard to get everything squared away, and today was D-day for the final tune...
On the Mustang dyno we used, the sucker made 126 hp and 116 lb-ft at the wheels. That should translate to 140/130 at the wheels on a Dynojet. Needless to say, it's a whole different animal... and a WHOLE lot more fun to drive. And the best part is, Trey got the drivability nailed. It idles nice, doesn't buck under part throttle, and it doesn't belch flames or anything. In other words, it drives like stock until you stick your foot in it.
Excellent work, sir...

Thanks, I had fun tuning it. The looks on your faces for the 6000rpm steady-state tuning was pretty funny.
The car is a pleasure to drive, it's doing everything right. Don't forget that we need to mark the crank pully (not the damper-ring) since it slipped.
This winter I'll have to tune the cold-start.

Here. Remember that the base timing was finicky. I approached detonation in a few cells in the mid range but hit MBT everywhere. I leaned-out the a little bit for 12.8-12.9. But this was the last log I kept.

Here is the billiard-table shaped 1.6 table I made.
I still want to do some cruise tuning on both cars. I had up to 38* spark and 16.5:1 on the dyno, trying to find knock and couldn't...so I'm going to road tune with the det cans for both guys.

I have multiple times, and confirmed balancer position.
I put in the top two rows of that timing map in my car just now and honestly cant tell a diffrence faster or slower which tells me i was past mbt and might have even started past it.
I just need to spend the money on the dyno, and find a place local that will work with me to do the tuning right, if i was closer i would just bring it to you.

Informative thread! I may try running the 1.6 map while waiting for a chance to get it on the dyno. A few questions, if i may:
Could I ask the reason for the slight differences in the map/rpm breakpoints between the 1.6 and 1.8 spark tables? Were they done that way on purpose because of the differences in the engines?
Could you show me the afr target tables?
Thanks!
