JRSC M45 tuning input or advice
 

Hello all and thank you for any help given... Need advice or input on what tuning route to go on '90 miata adjustable fuel pressure regulator, 320 cc injectors, 340lph fuel pump, header, 8lb flywheel HD clutch, AFM removal as shown on miatajoe.50megs,com newly rebuilt JRSC with 62.5 pulley have emanage ultimate and boomslang with 3bar pressure sensor not installed yet..and WB Wideband brand AFR and Boost gauges also not installed yet. What else might I install knock sensor etc? Again any input or advice greatly appreciated. Thanks for your time. Nick

I have a megasquirt running on my jrsc miata mines aswell a 1990 Stock fuel pump and injectors and clutch innovate wideband runs pretty good I’d suggest get a megasquirt what crank pulley did you buy in having some crank wobble issues knowing it’s a short nose crank in worried might be going turbo

curious, can you share your megasquirt files?..just need for a baseline? thanks very much

Megasquirt tuning
 

I can help you with tuning your car if you need it give me your phone number I can send u a good tune easily

I’m assuming you have a intake temp sensor so you want to run on fuel density there is a lot more to it than what I can tell you but if u are running megasquirt I’d get a exhaust gas temp sensor if you want to make sure it’s running safe that’s an easy way to tell .you have plenty fuel it should run good You will have troubles idling it’s hard with the supercharger and that long tube they sue if you get rid of the valve in that tube and make it short right into the charge pipe it should work better and at 8lbs might want to think about a intercooler soon but for now run safe timing

So you have a JRSC with basically stock everything else? I just got a megasquirt and I believe we have the same setup. Would you be able to send your files so I could understand what I'm doing a little more?

Do you have upgraded injectors? You will want upgraded injectors for an M45 with a JRSC, FF640CC injectors are great for running sequential injection
