Have to agree and I'm looking into cost effective alternatives for Brendan. Yeah maybe mate, but I wouldn't be happy leaving an ecu mapped without it having sufficient headroom for differing air density and conditions. Really wanted this to work as Brendan was royally ripped off by the garage supplying the MAP ecu in the first place. But i'm not happy with the MAP ecu, and believe me I've tried ! I've spent the best part of three days on it on and off, fitting it in around other stuff so I dont have to charge much. But it's just not cutting the mustard Possibly looking at an OMEX ecu for it, essentially an AEM but not as feature laden. UK based company and a lot cheaper than an AEM. I put these on 4 or 5 Marcos Mantis GTs with the modular 4.6 Mustang engine and a supercharger, so should be up to the job

Hey Marty, hope you are good mate The O2 signal is disconnected, and I will have a look at the injectors tomorrow.

The problem mate is the SC makes so much boost early on, more than a TT !

IAT trims wont adjust the fueling by that much mate

Oh agreed !!! Good call on the fuel pump I'll give that a try asap but not at the workshop now.

Hey Nod, it's making too much boost early on unlike an NA-T so it's just too lean before 3200rpms

Just been on the dyno again, and have to admit to not being a MAP ecu expert ! Rescaled the MAF 0 RPM 0 so that the ecu is seeing a higher voltage for 0kpa. Seemed to help a little but the basic problem is that at about 8-9psi of boost approaching 3200rpms, you just can't get enough fuel in, it's too lean even at maximum voltage and 40psi static fuel pressure. Then at 3200rpms it goes seriously rich, it shifts from 13:1 to 9:1, it's literally like a cliff drop ! The stock ecu is doing something to cause this, don't think it's going from closed loop to open loop on the o2 sensor as usually, and I could be wrong, once you are at 100% throttle the ecu goes open loop. You just can't map around this sudden shift in output fueling from the ecu. Open to suggestions ???

I've had a technical response back from MAP, just trying to get it back on the dyno as we are extremely busy. No doubt the results will be posted up Done a couple of MAP ecus before, seemed ok. But they were on a TT in the first place.

Okay, time I threw my 2p in here Firstly, Ryan and I get on very well, we have helped each other out in the past and will do so in the future. The good thing is that this forum particularly now has two very competent mappers that care about our beloved Supra and have had very good results in mapping them ! If someone wanted me to fit and map a syvecs\solaris then I have no problem doing this, and Ryan has no problem supplying me the ecu to do so. Like Chris Wilson says, choose your mapper and let them recommend an ecu based on their results and findings. As for the FCon, there is no doubting its competency and results. Ian C is right in that historically, those supplying the FCon in this country weren't particularly experienced with the Supra, they weren't overly friendly but they were overly expensive ! This is no longer the case. The FCon is a great ecu, particularly for auto Supras as they still retain an oem drive with the autobox yet they go very very well. And yes they are very good on manuals too. Everytime we've cracked Dudes engine open, the colourations have been perfect and no marks of det anywhere. So lets not stir anything up that isn't there and just accept that the FCon and Solaris are very good and the guys out there doing there best with them are serving the Supra community very well

PM Dude mate, didn't pay that much for his shimless buckets. Used my contact at TTE to determine what car they were from

Both Do Luck and Trial Supras gone in a week

A path you've trodden well The R32 is good fun mate, I shall demostrate for you Yep, a lot has happened in the last 12 months mate She has indeed gone to a good home, the car will continue to have money spent on it

Not sure mate, I will ask him TBH I couldn't watch it go, I left Dude to see him out Gonna get a bike soon, not a ballsout sports bike as I know I'll hurt myself. Something semi-sensible the gf and I can go for a spin on, probably an older blackbird or 'busa. Looking at a VXR8 too Plus I still have the R32 for sideways fun

Saturday was a very sad day, the Trial Supra is now in someone elses hands I usually get an offer or two a year and I've always said no, but the sad fact is I dont get a chance to use the car and it's been sat for nearly 6 months But she's gone to a uk home and yes I got over £20k for it, who says the right car wont fetch over £20k in the UK The new owner phoned yesterday to say he absolutely loves it, he's had some serious Supras before and in fact had a well known Supra built by an ex-trader. He said it was nice to get a heavily modified Supra where none of the engine lights are on, warning lights etc, everything works, goes like stink, starts, idles and drives really well But she will be missed 'It's been emotional'.

I've heard evening primrose is good for that mate

Agreed Shouldn't be anywhere as near as expensive here mate, we have the flywheel adaptor, spare loom etc so to install the 2JZ engine on the dyno shouldn't be a major drama. Makes it a lot easier if it's an engine you do regularly ! But without a doubt it's the best way to go. I'm very keen to see the difference, I think it's great to calculate the losses on a rundown but in reality I'm not sure how accurate it can ever be given the factors going into the difference from flywheel to tyres, gearbox, diff, tyres etc etc etc. But I'll be finding out soon mate

Paul has had an engine dyno before, it was a Stuska 1200hp model. Yes he had to have training and he will be passing that on I'm somewhat excited to get my hands on it, but it is different to a chassis dyno. You have a joystick in the control room with pots to control load and sweep speed for power runs, but with a power run you run the engine up to 'say' 2k, press the button for a power run and the engine dyno control system takes over for the run. As with a chassis dyno, you can steady state tune in essentially the same way, but instead of a throttle you have a joystick and a pot to dial the load in.

The engine is run in and power runs done mate, but the car still has to go on the chassis dyno for part throttle\low load mapping, cold start, hot start etc. The engine dyno is great but you still need to make the car drive nicely Better than that mate, sitting on a motorway for 500 miles or so isn't properly running an engine in, you need to put load on the engine too - so you can have pre-programmed running in programmes that apply load\revs etc in a way to properly run and bed the engine in. The dyno also has a blowby monitor, so as the engine is run in and the rings bed in, you can see the blowby coming down

Will know more on this once we've done one mate, which will be next week. Yep, that is also computer monitored

Exactly my thinking mate, I will be doing this as our chassis dyno calculates transmission losses on a rundown, so I'm keen to see how close it is or isnt It's worth mentioning, engines dont need to be monsters on aftermarket ecus to be run on the engine dyno, any engine we build can be run in and power tested on the engine dyno from completely stock upwards

Might have to run it at the next open day, should be May some time. Dude will be onhand for technical questions and laying rubber down outside

Hello mate, Yeah I'm dying to get my hands on it with a Supra engine. The glass is bullet proof, so no worries there !!! Sorting out all the final details for hiring it out etc. All the air supply and extract is balanced. Yep the air is recirculated god knows how many times and its all computer controlled. 7000L water supply tank. EGT sensors on every runner etc etc etc

Oh yes mate, that one should be fun - I'm sure there will be footage of that too, there's a camera in the cell so all built and engine dyno'd engines come with a dvd

Been working on this for a while, but it's all in and done. 2400hp Stuska engine dyno with full load control, run in programs etc The adaptor plate for the 2JZGTE has been made already and an AFR built 3.0 single turbo engine is going on next Here's the dyno with a race spec Morgan v8 on it. -oB6Gg81wlc 7dpiQ1k-QJg So if your serious about having your engine built, all run in and power mapped on an engine dyno, with real flywheel power graphs, you know where to come And yep, there will be footage of the Supra engine when it's done

Bloody Dude filling up the workshop with Supras, just cant help himself can he
