Is there something wrong with my 450cc injectors (used dsm) ? My Fuel pressure is at 40psi (connected to the vacuum line) and the car idles nearly perfect with the stock OBD0 ecu. Do my injectors provide too less fuel ?? The engine is a built b16a1 (9:1 pistons) with stock fuel pressure regulator.
Thanks guys!

how does it drive?

the engine is brand new so I don't rev over 3500 but with the hondata and 10psi of boost it drives quite good....

r u sure the hondata is curved for 450s already?.. mine didn't idle worth ****.. with my 450s on a stock base map

how is it a stock ecu if you have hondata??

I unplugged my SMC fuel contorller and my stock ECU did idle the 450cc injectors, but it wasn't smooth like you say it is.

it sounds to me its maped for the 450s, it would idel like crap if it wasnt, becarful new motor on base map dont push it to hard befor its tuned

@JonGP4
Yes the basemap that I got is already curved for the 450s. I'm from germany so I don't have the possibility to visit a hondata tuner so I told my complete setup to a hondata tuner in the us who worked out my basemap. I think it should be rather fine for my setup. I've a wideband O2 and don't drive around without having a look at it all the time

@Boostfedb18c1
I converted to OBD1 and before I hook up the hondata ecu I tried the bigger injectors with my old obd0 ecu.

Now I'm only scared whether the injectors work correctly. I bought them used and don't know whether they're ok.

I'm from the Netherlands, so I also don't have the option to visit a hondata tuner.

Which tuner in the US did it for you? And how much did it cost?

if you drive it and it doesnt bog down, you should be fine.

My car idled ok with the stock ECU and 450s installed...very very rich but idled. OBD0 pr4 ECU on b18a engine w/ dsm 450s

There is nothing wrong with your injectors...

If you're lacking a local Hondata tuner, then I recommend buying a wideband O2 so at least you know what your A/F is.

That will tell you ASAP whether or not they're working. The other option is to send them to an EFI flow bench. I know RC has one, but I'm not sure about the Netherlands.

I'm not sure how you figured hondata is a stock ECU when its already mapped for the 450cc injectors......................................... ................................

Get a wideband and make sure your a/f ratios are good and tune it yourself.

If you tried to run the car with your stock OBD0 ecu then it ran good??? was this using the OBD1 dizzy??

There is no way a stockECU can idle the 450cc, I tried it also. Ran rich as hell and car could not idle, just shuts down.

Is the AEM UEGO Wide Band Gauge Kit the best wideband to buy? Or which do you recommend? Or is it wise to buy one that can datalog? I've read that that the datalogging option on the UEGO is useless.
