Well the diypnp is only available for the S5 rx7 and up but soon will come out for the S4. I was wondering if anyone has one and whats different about assmbly compared to the ms2 v3 and v3.57.

It would be nice to have a good how to for the diypnp with pics and a break down of what you will need. If the s4 diypnp comes out soon i will be picking one up and if i get my knowledge straight on what needs to be done differently from the ms2 if there is anything. Then I will be posting a very detailed how to with pics and possibly video. If the s4 diypnp doesn't come out by christmas I may just reinstall my s5 engine harness but I don't want to )

 

well i found what i needed right here cant believe i missed it https://www.rx7club.com/showthread.p...ghlight=diypnp but its not showing in the megasquirt forum for somereason maybe its just me

 

As soon as Jerry sends me the S4 adapter, I'll do a quick writeup of what is necessary. It should not be very difficult at all.

sweet thats what i like to hear thanks

 

HI Ken, do you know how well is the diypnp reading the stock cas? I dont see any posts to adjust the vr signals,Or it read the signal fine as is without any mods?

 

Jerry told me it works fine on an S5, I have not tried it on my S4 rx7 yet. I will try it as soon as the connector is available though.

Ken

 

thanks!!!!!!!!!

 

What we've tested so far is a 84 GSL-SE with a DIYPNP hard-wired in. Car had an S4 CAS and coil packs. This car we fully tuned and it ran beautifully.

We started testing on an S5 car, got the car fired up and free revving out nicely, but we've gotten sidetracked and haven't gotten the car on the dyno yet to finish out the tune. If we see interest here from you guys that will tend to light a fire that helps make it happen faster. We got sidetracked because owners of other vehicles seemed more interested so we're testing on those cars right now. Squeeky wheel gets the grease .

 

One more thing-- the S4 model (N52 DIYPNP kit) will be available in about a month or a bit less. They'll be available in limited quantities at first though until my big shipment of connectors comes in. I only have 20 right now until that big order gets here. It's due in late in Nov, early Dec maybe.

 

do you have to do any mod to the vr input signal? I have problems with that before with the 3.57 board and you have some pics that you can share with us?

 

I have 2 proyects in my shop with s5 parts (rotary s5 powered toyota starlet and a fb rx7) and I have interest!!!!!!!! Ho else have??????? Im sure all in here have and are waiting for more info on the progress!!!!!!!!!!!!!!!!

thanks,Frank

 

You should not have to mod the VR inputs.

Ken

 

thanks!!!

 

Any update about this? Im in the its gonna be alive if I get an ems and get a new clutch stage. I have 3 options do the diypnp for the s5 and use my s5 efi harness, wait till the s4 diypnp comes out and use my s4 harness wich is on the s5 motor right now, or just screw all of that and follow arron cake's how to or muythaibxr's how to and go that route with a ms2. Part of me likes the pnp part of me likes the ms2 and the other part likes the built and tested ms2.

 

We've got most of the S4 parts in. Biggest thing we're waiting on is the case.

 

I just got an email from diyautotune after asking frore some calrifications. I thought other people may find them useful. Looks like all the extra parts required on the V3 bord will not be required on the diypnp.

Q:Will the diypnp have the second VR Sensor circuit?
A:Yes, it is already included!

Q:Will the diypnp be able to control pwm idle valves?
A:Already included again!

Q:Will i need to modify the bord to support and E-fan?
A:There are outputs already available capable of driving relays, which can then drive a fan. So... Yes!! It's already included :-)

 

S4 cases are in, and we've got the kits up on our website now.

 

im very interested in getting on has anyone brought one yet?

 

I just order one!!!!!!!!!!!1

 

I finish the asambly today and flashed the fimwere I will install it on a 13b turbo powered toyota starlet this sunday Iwill let you know...

 

I just got my DIYPNP S5 ecu today and with build it this weekend. This will be my 5th RX-7 MS install and first DIYPNP, but its looks like it will be another great product. Next I plan on installing a Microsquirt on my Yamaha V-Max using Honda VFR EFI throttle bodies in place of the stock carbs.

 

remember to jumper alt-cam to ground, that make me crazy because if not jumpered there is no rpm signal

 

We usually connect Alt Cam to ground with a 51K resistor instead of a jumper.

 

yea with a 51k I will soon test closed loop boost control and see what hapens

 

What pullup resistors if any are people using for vr2 and wled.
