"adaptronic" Engine Management Systems ?

No reason why you can't tune a street car without an air temp sensor but if the ECU has the facility to take one, do it.

[Adriano]

How do you figure that? Do you know how nuch the A/F ratios will change with temperature?

[msnismo]

I used to run of these... its not aimed at just 4 cylinders... my vehicle was the car Andy tested the plug and play board on for the 33's..... Never a drama, had a problem with the installation which ended up frying the ecu (unshielded wiring behind the gate melted). Since it was a dealer that did it a new ecu was available that very afternoon... just called said what had a happened.. went and got the new one and handed over the dead one.

Unfortunately as this was a couple of years ago it wasn't quite up to speed in terms of map points....the new computer due for release looks the goods though

Highly underated... my old ecu is now powering a 25/30 in an R31 quite happily ....

No figuring required. Did it.

few reasons, but they are a very simple budget ECU that gives competant results (tuned them on 4age's and turbo hondas)

i would seriously wait for a full 6 channel IGN and INJ model before fitting it to any of my customers cars.. till then it will remain the 4cyl base ecu.

I, and many others have ZERO issues running wasted injection and wasted spark. Including the 1UZFE boys.

I guess that would depend on the maximum RPM you intended to use vs the dwell time required by your ignition system...

Hopefully I will be able to let you know in a few weeks when I get my rb24 up and running and into the 9000rpm range to see how it handles it

it comes down to how many comprimises you want to make....... especially on a v8 1UZFE... dont get me wrong i have a killer big cammed AE86 here now with one im installing and tuning (if in vic feel free t drop past). i will post up the results in the next day or so.

Trent, if I am ever in Victoria, I'm definitely going to swing past to check out your setup, I hear a lot of good things, and would like to have a look-see and say Hi sometime, unfortunately though, I'm from Wollongong (Just south of Sydney)

I'm also planning to wait until Andy and the boys finish the new ECU, and I plan to upgrade to it also.

And....Howmuch did they change from a cold night to the middle of summer full boost power run?

[Adriano]

Interestingly without an Air temp modifier, the change in air density from 20 deg to 80 deg C is 20.5 % which if uncorrected would result in a 12:1 AFR (20 deg) going to 9.96:1 (80 deg) or if it was tuned with an air temp of 80 deg at 12:1, then you would have a 20 deg AFR of 14.46 !!

Don't care. Car went 9.30.

Adaptronics are quite unreliable, lots of great options but lots of dodgy drivers etc. That pulse racing at menai raves about them but apparently all their computers have been replaced at least once...

[Adriano]

Never had an issue with one. Only bad installations.

That's an incredibly general statement and I very much doubt it is backed up by anything resembling a fact.

[murrayis]

i've had mine for over 2½ years never had a problem with it, and i know a handful of people who have had them longer who havent had any issues

i've had a few with connector issues, they use the cheapest damn conectors for the main power and earth circuits its embarrassing. Other than that they are a capable low end budget ECU, i certainly would not run a big dollar engine off one though.

[murrayis]

Yea?

I am planning on running my build off it ? why would you not recommend it?

Yes I had a connector issue unplugging and reseating fixed it but.

just what you want on a big build.... an ECU cutting in and out at 7000rpm......

Honestley if the swapped to another connector type i would use more on 4 cylinders, if they upgraded again to 8 drivers then i would use more again.

Yep, I agree the New ECU they are releasing will have both of the above thankfully.
