Re: What is the typical Injector MS at Idle/Cruise?

Well the injectors are not from a large prominent company, they are from HunterTuned & yes I entered in the Dead Times provided.

It is definitely a lot better since pulling the timing back out at low throttle but still bucking & misfiring a little.

The plug are also gapped to 0.015.

Re: What is the typical Injector MS at Idle/Cruise?

I made some changes by pulling some timing out of the low RPM/Load areas & it did make some improvements. The setup is ebay Turbo, 1000cc HunterTuned Injectors, 255 Walboro, F22 SOHC stock bore (85mm) Wiseco Pistons, Eagle Rods, Stock Head with OEM valves, ARP head studs, King bearings, blah bla...

What is the typical Injector MS at Idle/Cruise?

Hey guys, Currently looking to see what is a normal rate for Injector MS at Idle & Cruising under 2,500 RPM. I am having an issue right now where the car is stumbling pretty hard at idle & cruising under 2,500 RPM. I have changed the spark plugs, the injectors, new battery & still the sa...

Re: H22A w/ 550cc injectors

Try this file, I just remade the injector size from my current H22 file that was using stock injectors. I just googled & found the RC Injector Dead Time page: https://www.rcfuelinjection.com/Portals/0/CVProductSpecs/RC_SL-550_Injector_Latency_Time.pdf & I listed the Dead Time on the tune fil...

Re: Upgrade from 255 Walboro to bigger?

Thank you.

Raised the pressure a little more & looks like I definitely lower the duty cycle.

Here is another pull finally hitting 11lbs.

New wastegate with 7-8lbs spring, the old one had a rip in the diaphragm & the spring was only about 4lbs.

Re: h22 euro R map

Here you go. H22 Euro-R in my 1993 Honda Accord on 93 pump. Intake, header, 2.5 Yonaka Cat Back, No cat. Replaced h22 Euro -r injectors to stock 310cc injectors (used injector box) from an obd1 H22 so you may have to change the size because idk what the stock Euro-R size is. Wideband: Connect to ECU...

Re: Upgrade from 255 Walboro to bigger?

Okay update:

I have an adjustable fpr now installed & it is set at base 43psi. The duty cycle is a little lower about 82% for the same pull as I uploaded before.

Would 50psi base pressure on RC750's too high?

Upgrade from 255 Walboro to bigger?

Hey do you guys think I should upgrade from a 255 Walboro to a bigger pump to lower duty cycle? I have attached two datalogs. I have the old fat body style RC 750cc's & the fuel pump is not relayed by the pump, so I am just using the stock wiring as of now. Would a relay setup at the pump help g...

Re: F22B Non Vtec (JDM) Turbo Tune & Pull, Suggestions??

Fixed the fuel leak on injector #4. The top o-ring either got twisted & crimped during my installation or the o-ring was bad. It looked like a hot dog if you put it in a deep fryer lol. 58 degrees, night time..did some pulls. About 6.2lbs with 13 degrees timing, 52% duty cycle, 5933 RPM, TPS 63%...

Re: Inject Dead Times Voltage

Awesome! Thank you for that information. I just did as you said & it seemed to run pretty well. Just messed with the dead times around 12-14V for a clean idle & all seems well.

Took the EK for a spin & the AFR's are actually pretty dead on.

Thank you!!

Inject Dead Times Voltage

Is there a way to actually adjust the dead times voltage numbers accurately? If I put 9.00 V it automatically jumps to 8.96 no matter how I put the number in..if I try to put in 13V it goes to 12.13V. The RC Injectors spreadsheet gives a breakdown of what Voltage is per what dead time but I cannot g...
