Default Trouble starting my 99 Miata.

Hey guys,

I just finished installing my ECU on my 99. The car is naturally aspirated with stock injectors, 1 bar map sensor, and the stock IAT sensor. Here is what I have done after plugging everything in with pnp harness and wiring the map sensor:

1. Loaded the NB8A base map from 8/5/09.
2. Tried starting (Car cranks but won't turn over)
3. Checked connections. OK.
4. Flashed the firmware to the latest.
5. Reloaded the same map.
6. Tried starting. No luck.
7. Calibrated my TPS.
8. Set O2 to OEM narrow band.
9. Tried starting. No luck.

I checked through all the Adaptronics threads and there was two similar posts. One had no replies and the other the guy said he "set timing" and it worked. Am I missing something here? Stein said his stuff started right up first try. Any input would be greatly appreciated.

**Also, I forgot to mention, I connected my map vacuum line to a capped nipped on the side of the IM closest to the firewall. Is this not an appropriate vacuum source?

I am using the same source for where my map line is connected. you should be fine.

You need to calibrate your map sensor. Since it is a 1 bar map sensor, set the max map reading under the analog tab to 100 kpa then with the ecu running and the motor at rest click learn to get the correct adc value. this will set 100 kpa to your atmospheric pressure.

As for the min map reading, you will need to use a vacuum pump (brake bleeding tool with a gauge) from a friend, or sears, or harbor freight, or wherever you can find one.
then set your minimum value, create that same value with the vacuum pump ant click learn.

once these are done SAVE THE FILE, then try starting it.

BTW, i think that it might be tough to tune your setup with just the oem narrowband o2. Not impossible, but i wouldn't want to do it personal

I just noticed that check engine light does not come on when I turn the key to ignition. With the PNP harness, is the check light still supposed to come on to show that it sees the stock ecu?


Swimming, I am not going to tune the setup. I have a tuner that I take my cars to and he uses an LC-1. I just want to get the car running on the ecu with a base map before I proceed with really modifiying it.

If you can't get it fired tomorrow Quinn give me a call and I'll get you through it. That NB8A 1 bar map should be pretty solid. I had a customer that started right up with it yesterday and went driving around. If you send me an email I'll send you another map to try.
