SMT8-L

Frequently Asked Questions. |
What do the values of the SMT8-L's ignition map actually mean on the engine's timing?
Which wire should I start the installation of the SMT8-L piggy-back with and which wires should follow thereafter?
The RPM in the SMT8-L LetRipp tuning software and Rev counter do not match?
What does "teeth per inject" mean?
Can the SMT8-L piggy-back work with wide band lambda and narrow band lambda probes?
Can the SMT8-L piggy-back alter a road speed governor?
How many analog channels can the SMT8-L piggy-back modify?
Can the SMT8-L piggy-back compensate for engine and air temperature changes?
Can I use the SMT8-L piggy-back to remove my airflow meter and use a MAP sensor instead?
My engine has two additional MAP sensors as well as a MAF sensor. Can the SMT8-L work on my car?
Does the SMT8-L piggy-back have two tuning maps?
How much power can I expect to gain from fitting the SMT8-L piggy-back to my car?
Is the SMT8-L piggy-back the right choice for my car?
If I am not using the air and engine temperature inputs, what should I do in the maps of the SMT8-L piggy-back?
Why does my throttle position start at 14% and end at 85% on the SMT8-L piggy-back?
My extra injector is not working. I have used wire 7 of 10 on the SMT8-L.
What does analog mean?
I have wired my airflow meter into the analog 1 circuit, but now my engine will not start.
The RPM in the SMT8-L LetRipp software and Rev Counter do not match?
The engine does not start after cutting the crank signal?
I have teed onto the crank sensor with pin 2 of 14, the +crank input, but I don't see any RPM in the LetRipp software when the engine is idling?
My RPM is double that of the rev counter. How do I get the correct RPM?
My crank signal is on one wire. How do I know if it is a magnetic or digital signal?
I have heard of the term balance crank signals. What does this mean?
I keep getting an ignition error and the SMT8-L will only retard the timing. Why?
Signal | Teeth per turn | Edges per turn |
60-2 | 60 | 58 |
36-1 | 36 | 35 |
36-2 | 36 | 34 |
24+1 | 12 | 12 |
24+2 | 12 | 12 |
1 pulse per fire 4 cylinder | 2 | 2 |
1 pulse per fire 6 cylinder | 3 | 3 |
1 pulse per fire 8 cylinder | 4 | 4 |
When I use the SMT8-L to control the boost on my turbo car, the engine light keeps coming on and the error code is about the N75 valve. How do I fix this?
I have used wire 8 of 10, but I cannot get the boost solenoid to pulse no matter what values I use in the boost map?
I am trying to pulse the boost solenoid at 50% but the actual boost PWM is 63% in the data display?
Am I able to modify the ETC signal with a SMT8-L piggy-back?
What is ETC?
The engine has two narrow band lambda sensors before the catalytic converter. Can I modify both using the SMT8-L piggy-back?
If I want to tune the wide band sensor must I cut the 2.9 Volt wire on the wide band harness?
If I want to tune the narrow band sensor must I cut the 0-1 volt wire on the narrow band harness?
