Marks RX7 - lets break a rotary.

Liked for the steps forward not the steps back!

Bit annoying the wiring isn’t spot on but I guess that’s the beauty of one off custom parts, hopefully the loom guy and anyone else involved with the niggles get them sorted without too much hassle.

Looking forward to living the brap life vicariously soon…..
 
To quote the most used phrase of the last few years, it is what it is. Things are not always as they’re meant to be and it can catch people out. It’s not until you go to use stuff you find it out, you’ve got the right attitude towards it which is the main thing 👍
 
Not much happening today as work has been pretty busy and waiting on a few parts. The water level sensor and bigger air filter should arrive tomorrow.

I did manage to quickly fit the new FPR tonight though. No more leaks and a black one matches the colour theme a bit better. I did have to keep the blue fittings though. 😂

I had to double check and question the catch can set up but I think I’m going to run with what I have for the time being and see how it behaves. At first I didn’t think the catch can had a filter but Radium have designed a larger filter on top built in as shown in yellow.

I’ve swapped over the silicone vacuum hose to the FPR for an AN4 line instead.

In ECU/config related news it turns out the water level sensor was not working but I managed to source one locally which has fixed the issue.

The other issue we were having was the DBW being inverted, swapping two pins over at the throttle body has solved that issue so that’s sorted now too. Still a few issues with wheel speed sensors and PDU data being sent to dash, hopefully have this resolved this week.

Finally I’m sending the clutch switch to Matt at LMW to knock up the correct plug/loom.

I know you all look forward to my little updates so didn’t want to disappoint though not too much to report.😀

I’ve sent centre console back to wiring shop to have the new Syvecs switches swapped out plus the clutch switch loom sorted so I can incorporate flat shifting. These should be back with me Thursday.

The tuner and I are going to spend some time tomorrow checking ign/spark (CDI) and crank sensor, basically as many checks as possible as the car is likely going to have to go back to have the wheel speed sensor wiring amended due to interference from the fuel pumps.

The plan is to get the car up off all four wheels and double check tomorrow. I even had to buy a new jack today as my last one shit itself leaving fluid everywhere, luckily I always use axle stands. If we do encounter any other issues though at least they can be resolved back at the wiring shop rather than me attempting it at home.

The ECU needs to go back to Life Racing to have the board amended for my CANBUS requirements too and whilst it’s there they’ve agreed to update my dash as well. I’d hazard a guess this is going to put the first start back by a few weeks. Oh well, keep plugging away. 😁
 
It’s been a few weeks since an update.

The ecu and D4 dash came back earlier this week. Life Racing had to make some amendments to the board to allow us to see all of the PDU information on the dash which also is required for safety measures and alarms.

Good news is all of that is fixed now so that’s a result.

Another outstanding issue was the wheel speed sensors seeing interference from the fuel pumps. The tuner has managed to solve that within the software by messing with frequencies. So a big tick there too.

Next up we had issues with the calibration switches for MAP and traction control. Finally solved too, partly my fault on this one because I didn’t realise there was a lockout switch on the rotary dials to allow me to get to the full 12 positions we needed.

Now the good news is we are almost ready to fire it up. It’s probably going to be this time next week due to other commitments for both the tuner and I.

It’s just a case of testing crank signal, checking ignition and fuel injectors. Prime system and pray to baby Jesus. Not doubt there will be some other issues along the way as let’s be honest that’s just the nature of this car. 😂

Oh I also managed to fix my side lights.

Full transparency I’ve had a nightmare today and I’m so pissed off with myself. I’ve come here as my safe place, it’s like my virtual therapy couch.

In short I was raising car and was trying to get jack stand in the right place. It got stuck under the car in the wrong place and the jack slipped, car lowered and jack stand went through the floor pan. I’m fine and I know it could have been worse with me being injured but I’m absolutely gutted. I’ve spoken to Anil and he said it can be fixed easily enough but it’s just the additional stress and money of it all.

I swear this car is cursed, I don’t believe in all that voodoo shit but it’s truly amazing how much this car pushes me to the limit.

Today was supposed to be a day of joy after over a year of taking this route of a big change in set up and although the engine has started and sounds mega I just feel deflated. See video below.



As much as I’m pleased that a big milestone has been reached the car continued to fight me even after the first start.

Basically the circled fitting below is the oil return from my turbo pressure regulator and it returns back in to the filler neck. Due to the design of the filler neck and as the catch can fittings come off it too, the filler neck cannot drain quick enough which in turn fill the catch can line followed by the catch can itself. So after running the car for 90 seconds I was greeted by over a litre of oil spilling out of the catch can.

In order to solve this issue I have ordered the new Turbo Smart pressure regulator which has just been released which is a return less system. Another £160 spend plus the cost of the floor pan fix.

Not a good day 😢

Oh there’s also a decent exhaust leak on the exhaust manifold side so not looking forward to messing with that

I think it’s a case of putting the car away for a week or so to help reduce my want to set it alight.
