MSPNP 90-93 Miata 600cc injector problems
 

I installed my DWerks 600cc injectors today. I did the settings in tunerstudio where i punched in the engine cc,injector cc and how many cylinders.

I had a 205cc org fuelsystem before, i have added a 255 walbro HP pump and today the 600cc injectors.

My problem is that my car goes so rich that i can't drive it or get it tuned:\ I tried to divide the crank pw numbers by 2.97 (approx what the differential in injector size is) and punched inn all the numbers . Did not help me at all - car wouldnt even start, if i switched back to the basemap that came with the ecu it starts but runs like crap. It can be driven.

I tried to alter these ASE settings also but didnt see any difference:\

What am i doing wrong?

Setup:
MX5 1990 1.6 - JRSC @ 60/150mm pulley - 2.5" exhaust - MSPNP ecu with extra software. Im running a registered Tunerstudio software. Norwegian Blyfri 98octane ~ 93octane in the US as fuel.

I took the car for a drive earlier today and when i get boost i get a hardcut on the fuel or ignition. Tried roadtuning it a bit, but it wont run as i did with the 205 injectors and only the 77.5mm nosepulley. I hate when the car dont work as i should since i need it to get around..

Please help me with this guys!
I can upload a log from my road run if needed, and pics of the map as it is right now - the way it is now i atleast get to the store and back home.

Here is the map and the logfile from earlier.

I cant get the car to start on this when i turn the engine off.

So i have to use this map to get it started:\

Really need some help here guys:\

Your acceleration enrichment also needs to be dialed back - it's dumping in way too much fuel, probably triggering too easily, and seems to be implicated in most of the running rich in that data log.

May i ask how this is done?

Did you remove the AFPR?

Yes, its long gone:)

Use the Acceleration Wizard. For more detail, see here.

I think i managed to fix this: ) The car feels much better after some tweaking:) I'll post some logs and a copy of the map tonight so you guru's can see if its starting to look ok.

Thanks for the help so far:)
