MSPNP2 dwell settings
Base map for a '94-95 1.8 has it set to 3 or 3.5, I forget. Regardless, we had some throttle tip in issues. It was hesitating for a split second when we'd jam the throttle. Raising it to 4.0 really helped, 4.5 REALLY helped. Even the owner, who's raced more Miatas and other cars than I can fathom, was impressed once we upped it to 4.5.
On another project with a MSPNP gen1 and 1.6, I don't THINK I've changed the running dwell, and it's currently at 5.0. Both cars run stock ignitors/coils with NGK blue plug wires. Two questions: 1. Am I on borrowed time with 4.5 dwell with his '94-95 coils? 2. Is the MSPNP and MSPNP2 (and 1.6 vs. 1.8 coils) compatible for dwell settings? Should I just up the 1.8 to 5.0 like the gen1 1.6? Thanks! |
Interested in what responses you get to this question.
My MS2e in the 94 behaves in a similar manner. Even with the TPSdot threshold set as low as 20%. Sounds like upping the dwell might be one solution? |
It was night and day.

Well, the MS9495 map has the dwell set to 3ms.
And for fun I decided to use a bit of Google-fu and found this... Dwell settings for 1.8 liter coils in the 1994-1997 cars: These coils charge faster and need slightly less dwell than the 1.6 coils. Dwell Control: Dwell Control Cranking Dwell: 7.5 ms Running Dwell: 4.5 ms Over at the DIY Auto Tune website. So, from the sounds of it, maybe 4.5 is bueno? I went ahead and updated my TS and will see how it acts tomorrow. Thanks for the info. |
What firmware are you guys running?
|
I'm fairly certain I'm on 3.3.1.
I checked the readme notes for the 3.3.2 firmware and the only improvement of interest was the updated rev limiter settings. The coolant based rev-limiter kicks in way too soon, no matter how I configure it with my 3.3.1 and TS 2.6.04. I've put off disconnecting the coils to update the firmware for now, since it's a fairly easy thing to live with. |
Try upgrading to 3.3.2.
|
I updated to the latest and greatest from DIY when I tuned the car 2-3 weeks ago, 3.3.3.
