confused with hsf pcb
 

Hello
I am a little confused with pcb solderind pads to run x1.5 idc or maybe more (engine setup below)

picture taken from this forum but I havethis type of board with no marks like on this one

The second is- I am running 3 (1000cc) jets and user manual suggest to solder 1-2-3 pads to 2-3 is it corect because manual section has doubled chapter #6 but it is pionted on chapter7.
Setup is
nissan rb26 with 3.4 strocker kit
efr9174
2200 bosch injectors
at 1.2 bar I have 525 whp and only 48%idc on pump gas

Re: confused with hsf pcb
 

I suggest using the x1.5 + the "GAIN" trimmer. Ideally using x2.25 (available on V3.1)

Re: confused with hsf pcb
 

Solved, this board revision has a jumpers set on opposite
did x1.5 and pad 2-3 solder for 3 jets, seems it flows reasonably
but see no power gain((
tested at mustang dyno
started at 1.2 bar with gas afr 11.5 , injecting pure ethanol (96% grade) went to 10.5
pulled -10 to 17% of fuel to match11.5 gas afr and no power gain(((
added 3-4*, got +10 whp an average, added 5* no luck
total timing 18 to 24* with wmi active

Re: confused with hsf pcb
 

try adding boost

Re: confused with hsf pcb
 

I did, at 1.4 it made 595 with injection and neraly the same 580 or so on pump gas ron98
I noticed power gain on afr12 ,550@1.2 during pump gas run
Going to test afr 12 with injection but I`ll have to remove 20-22% of fuel and true gas afr make me scare
the jets are 3 x 1mm not 3x1000cc as I posted above

Re: confused with hsf pcb
 

perhaps the turbo has reached its peak flow?

Re: confused with hsf pcb
 

Can you not get methanol?

Re: confused with hsf pcb
 

it is efr9174 wit capable flow of 96lb/min i am sure there is enough room for power grow
yes , I ll try to do so.
The next step we will try
- get a race gas ron109 and see the diffrenece playing afr and timing at desired boost 1.4 bar
-replace alcohol we have now (96% ethyl spirit allowed to food industry from "known guy" ) with methanol from in sealed tank from manufacters (its not easy to get because of the regulations and restrictions)

Re: confused with hsf pcb
 

I have spotted a soldering error, can you please correct it.

Also add solder link MPS to the iDC to obtain 70/30 idc/mps flow progression. this will provide some boost/flow compensation on the system.

this picture taken from another topic of this forum
checked mine board and there is no solder
will do boost compension during this week and report back

Re: confused with hsf pcb
 

why send a board that doesn't belong to you?
