Had some issues getting the plumbing right, thermostat didn't like the header tank feeding in next to it, wouldn't open, so put the feed in upstream of that and it works fine, fan is kicking in and out and hold temp nicely.
Had a few MIL codes to sort out but they're all done now, cold start and everything seems fine, although I still cant drive it obviously, the only code I'm getting now is 11, which I can't find any info on, but I only get that with service wire shorted, no MIL when running so prob not worth worrying about????
Existing loom is not in good nick, lots of hard/broken insulation so next step is a new loom, which brings me to my next decision.
I've found somewhere that sells ecu plugs and pins, so do I stick with my JDM OBD2A ecu and use a harness to convert to OBD1 for Hondata, if I go that way, or do I just make the loom to suit an OBD1 ecu and go straight to Hondata?
I'm leaning towards going OBD1 straight away, I guess my questions are,
1, what are the pro's and cons of going to OBD1, what sort of gains would I see. Engine is stock atm, bigger TB and completely different intake from stock, PLM Toda extractors into full 2.5' mandrell bent exhaust, no PS or A/C, lightweight flywheel and clutch.
Would the stock ecu run that as well as a tuned ecu?
Does the JDM ecu have the 180kph speed limit?
2, what sort of maps do the Hondata equipped ecus come with, will it simply plug and play with a similar tune to what the stock ecu currently runs, and fine tune from there, or will it require a full tune from the start?
I have neither the gear or knowledge to tune myself so will be dependant on someone else to do it for me.
