Ok guys im planning to turbo my crx si when i pick it up soon and i wanted to know what i needed to get me going tuning wise. I know i need a d15b7 dizzy and p06 ecu but i wanted to know what is the cheapest way to get my moving.

Could i just use this chipped p06 and go to a neptune professional tuner near me ? could this work?

Chipped OBD1 Non-VTEC ECU with Custom Basemap Chip Package

or do i have to do the full package?

Neptune RTP / Demon V2 / P06 ECU Package

thanks in advance!

If it iz a 90-91 stock si pm6 ecu you can tune it with turboedit with just chipping it basically,

If you wajt to convert to OBD1 you need an ecu adapter harness, a dizzy adapter harness, and OBD1 non vtec ecu and dizzy, you will also need to convert to a 4 wire o2 sensor unless the program you run has the option to use a single wird o2.

Any neptune dealer should be able to provide you with all that you need. You can delete the o2 sensor in neptune so no need to switch. I personally leave the tune in open loop unless they have a wideband to run closed off from.

TO cover yourself.
YOu need a obd1 conversion kit. dizzy, o2 sensor, wiring ecu etc...

Next you will have to talk to your tuner about the neptune.
Some dealers will have the ability to burn chips. So you will be able to go with the chip setup.

Others dont and you will need to get the rtp bundle.
