Bog on acceleration is usually a problem with AE. AE is best tuned by feel, not by watching lambda on accel.

I just skimmed through the last couple of pages and now know that you don't have a v-tps on this engine. ΔMAP is not going to be a great AE tuning strategy for this motor. ΔTPS will improve things.

That big dip in your fuel table suggests that you need to work on your intake.

The new rules allowances for SM would have them point out in PTD/TTD this year.

I think you're a bit nuts calling a 1:27, but if you're ok with sporting the tampon on your dash for another year when you don't hit it, I'm ok with that.

But, on a high note, I've got 4 of those shitty red CARB gas cans to haul fuel to the track - you can use them if you promise never to bring them back.
Your incredulity may stem from being so far off the pace in your PTE car. At NASA nationals, they're about the same. The PTE cars on our team are about ~1s under SM records. Our PTD cars 2-3s. Crusher (PTC) about 6s, all on >2:00 course. Figure 25% lower delta for a 1:30 course like Hallett.

Hustlers car will be a slightly off pace C car until its dialed so I could it doing a 1:29. Crusher should be able to do a 1:27 if its not too hot.

That's the first thing I saw too. If its an MS1 PnP, add a damper to the vacuum line. I found that the sharper intake pulses from an open intake and header trigger the onboard MAP sensor even steady state. Turn down the sensitivity and it bogs.

VTPS is the answer but just damping the signal line to the MAP will work in the mean time. I used a tiny paper inline fuel filter off a lawn mower.

I have the MAP damper, don't have a pig-tail for the TPS and don't know how to solder solder he board for VTPS.

I'm so pissed that I'm going to the gun range.

No shame in my game about the times I'm putting up. My goal this year is to just be faster than the guy that's DFL in SM and to run close to or better than other Miatas in TTE where the drivers are usually instructors or have way more history than I do. I've done well with both and have had a blast doing it. I know I'm not fully prepped or optimized with the zero point mods and I've still got to cage the car and points to spend to max out E. I've got gobs of raw time to pick up just with spending my last 5 points. It's all just time and money, right?

No doubts about the times you'll post in Crusher, either. Crusher is about as well prepared, sorted and tuned as a Miata can get to run in C. You've got loads of seat time. Good combination of things to go fast right there.

My doubt was with Hustler pointing at the center field wall and calling his shot again. Two seconds faster than he ran last year with a car he just took 70-90hp out of. In a year where his seat time has fallen way off. Perfect setup for a huge miss and another year of self flagellation.

We all poke fun, but it sucks.

Don't have any friends that build computers/circuit board type ****? I got one of mine to solder my mspnp board, took like 5 min.

Half Hustler's problems would be solved if he wasn't afraid of the post office or had the time to ship stuff.

Most of the modifications he's cried and/or worried about would be done completely free if he lived near me, and are free if he ships me anything. Sounds like he's in a fabrication black hole.

I've had to do an engine swap, find parts, and get it running in 5 days, working after I get off work...this has not been fun.

Didn't say it was fun, I just meant that you sound really pressed for time and don't seem to have a lot of fabricating friends close to you, sucks, but you've gotten a lot done.

Do you have a 99 TPS pigtail and want to solder stuff today?

No on the harness, and can't really help today unfortunately. Other half had gall bladder taken out, playing nurse for a while. If you still need help within the next couple of days I should be able to.

Dude what the **** is wrong with your ***? At least half of your posts are about irregular bowl movements or corrective surgery.

Thanks. After Hallett, this car get's parked until I get a real computer and proper injectors...after paying off my debt. I'll probably track the car again next summer, lol.
