because it's more stiffer than the OEM one ??

nice project

[elardv23]

your car is awesome.....
do you know where can i find body kit pictures??
i'm working on my toyota corolla ae 86, but i want some pictures, so i can have ideas to put together,.,.,.,

I'll be glad if you can help me.

I guess I can't, because I have not put my mind into it, and I don't tend to. If I had the money, I would have put a CBY kit with some insane offset wheels. But it is just to expensive.

Try googleing ae86 body kit in "pictures"

Best regards

Well, I havn't had the time to post some news over here, but megasquirt tuning is turning out to be a little more difficult than what I thought it would be.

Anyways, everything is actually working and VE and Spark table are being done. Initially I've had a lot of detonation due to having a spark table from a friend's engine and I realised it would have to be changed...

The spark table is now rising from 20º til 25º @ 5000rpm and fixed past it.

Almost no detonation and the engine is revving fine. It stutters a lot when below 2000 rpm and the cranking and idling is still not good enough.

Can't get it to crank below 10ºC and the battery is getting tired of it.

Had the accel wizard using TPS setting but didn't manage to tune it properly so I changed to MAP which turned to be a lot better. Not perfect... but better.

I think I have to raise the spark table on low throttle so that I can get better response.

Warmup, acceleration enrichments and other aspects still need a lot of tuning, but it runs.

I just need more time to spend around these subjects.

Best regards

Hi Apardal:

congratulations on a fantastic project i have just read the whole lot from page 1 to 17 and have a lot of respect for the work you have done.i am currently doing my own project demo car for my company in Ireland and i can safely say that after seeing your project it has really given me a boost and make me want to go just that little bit further to get it perfect.

Thanks for the inspiration and hope all goes well for you with the rest of the build.

[apardal]

Thank you cab32!

Good luck with yours!

Went to the dyno yesterday! Trying to figure out what was the power output...

- first test, setup made days before so that I wouldn't hear my home made engine stethoscope pinging... with ignition timing very low.

23º ignition timing above 5000rpm

120.4cv@7800rpm e 117.9Nm@5259rpm



- second test, tuned the mixture and lowered the ignition timing. Thought it could be detonation holding the power down!

20º ignition timing above 5000rpm

116.0cv@7888rpm e 124Nm@4562rpm



At this point we decided we should advance the ignition timing since from the moment it detonates, the engine will loose power

- third test, with data logging always on, another tune was made to the VE map.

26º ignition timing above 5000rpm

135.9cv@7896rpm e 128.7Nm@5123rpm



15 hp gain with 3º advance... time to go further

- forth test, removed the air filter

30º ignition timing above 5000rpm

163.4cv@7588rpm e 155.3Nm@7061rpm



We were impressed, 7º of ignition advance gave 43hp with a setup that
initially looked like it didn't work.

I could have tried another test with 2 or 3 degrees of advance but I went to the dyno to make just one or two tests and I was already way off my budget!

I think the torque curve is alright, because it's good through 4500rpm until 7000rpm but the value could be a little higher, maybe with a little more ignition advance it will be better. I draw the conclusion that I've no need to have the rev limit at 8700 since my max power output is around 7500rpm.

At the moment, I'm trying to figure out what's the thing with the noises from my home made engine stethoscope because what I thought was detonation, can't be, because it will make strange noises with 23º of ignition timing and with 30 it makes a little more noise, but gains 43hp. If it was detonation, there would be no power gain, I think.

On the road we tried to figure out what detonation would be and raised the ignition timing to 45 degrees and the noise becomes more intensive, for sure, but it is difficult to understand at what point detonation starts.

I'm going to try to drive the car without the stethoscope and raise the ignition advance until I can hear detonation loud and clear and then I'll lower it by 3 or 4 degrees.

Right now I need to decide whether I'm going to install ITB's or not, if I'll change my cams to a more aggressive setup or if I'll leave it be. Either way, I'll need better oil cooling devices...

A video made today driving around the new setup!
