240z + 1JZ-GTE (manual)

Getting pretty close to finishing the wiring but not enough to start yet. Had to alter the TPS wiring and need to run some extra wires for the injectors as they are currently wired for batch firing. Also need to wire in the new lambda sensor and that's pretty much it. Will have another play tomorrow.
 
Good luck with the wiring, I don't envy you, takes a long time to do it well and neatly.
 
Finish enough of the wiring, with a lot of help from my mate Ian, to get the car back up and running again and started loading some values into the maps. There are an awful lot of software options for the ECU which took Ian, who knowns these inside out, quite a while to configure. Then the sensors needed calibrating along with an ignition timing offset because I am running adjustable cam pullys. We spent a few hours already and that's just got it running with basic ignition and fuelling. It does run smoother and revs quicker than the old Toyota ECU already. Cant wait to start driving around in it. Still need to sort out a lambda as the old Toyota one doesn't use a boss so couldn't swap it.

Loads still to do but we're heading in the right direction. Here a quick taster vid. The car shut it self down after a few seconds due to lack of coolant pressure.......forgot to tell the ECU we didn't have a coolant pressure switch!!

Good work there, glad to hear its up and running.

Yes, theres a lot of settings and sensors to set up on these ECU's, although I actually enjoy that part. Its just good to get the wiring out the way.

Will be good to see your results this year with the new ECU.

Any idea what sort of difference it'll make to performance John?

I'd imagine he'll be able to get better performance from the engine. But also depending what he's setting up: launch control, traction control, boost by gear, flat shift and then the safety benefits of being able to set up limits for oil pressure, water and oil temp, boost, AFR and more.

How advanced are you planning to go John?
 
The old ecu was not mappable in any way. So it was not possible to get the best out of the engine or get the afr's to a reasonable level. This should allow me to not only get better performance from the car but also improve its running under all conditions. Then there's all the extras that Ian has mentioned to improve safety and aid drivability.

The car has always been an evolving hobby and the ecu swap will allow me to take the car to the next level and way beyond. The engine is currently standard apart from the cams. Now I have the ability to control any upgrade I choose and still retain drivability. The extensive data logging also allows me to monitor the effect of every tweak and improve the car without paying a mapper. At the end of the day this was a very cheap mod that will unlock the potential of the car so was a bit of a no brainer.

Long live the 1JZ :driving:

I am confident you will unlock some more ponies;). ..

Dare I say had it been a RB under similar conditions, it would have been on its 4th rebuild:rolleyes::devil:
 
Engine go for around 1k although there was a good complete one for £850 on eBay a couple of weeks ago. R154's are anything from 1.5k to 3k.
 
Managed spend a couple of hours, with my mate, on the car today. Started with the cold start and base maps. Got the car ticking over nicely with good AFR's and idle control keeping it at 700rpm. Spent a while on the pickup from idle and low revs under load. Progressed enough to actually get the car out on the road so took it for a drive to get some numbers in the fuel and ignition maps. Didn't venture into boost but it now feels like we're getting somewhere.
 
I usually nap on the sofa.

Because we dont have a base map there's an awfull lot of numbers to put in on all the maps before we start burning money on rolling road time. The mapping we are doing now is all FOC so we will get it as close as possible before booking a couple of hours at the RR to finish it off.
 
Finished the rest of the wiring yesterday which included fuel and fan control plus the new lambda. Ian also had another play with some mapping of the lambda targets. He has also finished the base maps which I'll load the ECU with tomorrow. The ECU has gone back today to have dual knock control installed which was forgotten when he ordered it. We are making progress but the end still seams a long way off.

I still need to get my head around the mapping as at the moment it all looks very complicated so its all left to Ian. I need to take over at some point so as I'm at the workshop most of tomorrow, as the white shell is being collected, I will try and go through the vast options in the ECU software and try to simplify it in my head.
 
More progress.

Dean helped me yesterday, keeping an eye on the laptop as I drove around a bit. Then Ian came out with me for an hour or so and we got loads of mapping done. It now drives just as nice as with the factory ECU. Ticks over smooth and pulls cleanly at all speeds. Drivability is great. Ian has not allowed me to drive the car around but I'm told not to use over 30% throttle and keep out of boost. I'm downloading all the data logs each time I drive the car and sending them to Ian to analyse. I'm starting to get the hang of working out what they mean and which maps to alter but haven't made many changes yet. I'm still only running a maximum of 20deg of ignition so once the fueling is sorted we will move onto that.
 
Chears Ian. It is getting there but with events looming, I'm getting a bit nervous that it won't be ready for silver stone or spa a couple of weeks later.
