hi guys need help again

b4 i went to the ecu recall the rev limiter kicks in at about 8000rpm, some time 7800rpm, went to the ecu recall, so there should be a new ecu in my car, but rev limiter still kickin in at the same point!! the car is warmed up and everything, i thought the new ecu would solve this problem, hopefully they didnt just put some octane booster in instead of new ecu, what do ya guys think the problem is????

Go back to them and ask them

They will prolly tell you that you shouldn't be driving the car to 8000 but if it is not the same as when it went in then you should speak to them first....

i had the same problem b4 i went to toyota, thats the bit that worries me, because some members on here had this problem and they solved it by resetting the ecu, and i went to toyota to replace my ecu with a new one by the ecu recall, and the same problem is still there, with a new ecu shouldnt it be 'starting fresh'?

hey sportivo,

I have also noticed that. It sometimes happens to myself, I have heard from a friend and it could quite possible be true that the guage cannot keep up with the engine. so the engine revs faster than the needle can keep up, some one please correct me if this is a load of rubbish..

Mine has always cut in before 8000, I just assummed that it had something to do wih not every engine being identical. Got the 80k service this week I'd say, so will ask about it then, and let you know.

What does flashing the ECU accomplish?

mine was fine when i first got it cut out at 8200rpm, i didnt have heaps of petrol in once(it still goes but the light came on for a long time) ever since than it cuts out at 8000rpm, i thought a new ecu would of fix it, just strange to me that the memory from the old ecu is carried over to the new one....anyway i will try and reset it

I dunno about that after watching the clips of the supercharged 2ZZ, man the guages move fast B)

My old Stivo used to sing happily to 8200 before the rev limiter came to the rescue, when I picked up my new stivo (last one stolen - see other thread!) I got a rude shock as the limiter kicked in at around 7800-7900! I was not a happy camper as the extra few revs makes a big difference in the shift to the next gear. I rung its little neck a little - put some petrol in and the rev limit increased? to just after 8000? Did an ECU reset and put in a full tank of 98 octane go juice and wham up to 8200! :yahoo: It could be that my prayers and dedications to the gods of LIFT have been answered or is it an ecu setting somehow linked to octane rating of the fuel or fuel quality (I sure it wasn't full of the good stuff when I got it). This would make sense if you are running a lower octane and higher revs that to avoid detonation (pinging) there was a restriction on the rev limit. Could this be the case?

no, because i always have 98 in, no matter what brand as long as its 98, similar thing happen to mine, it was cutting in at 7000rpm, and than 7600? and now 7800/7900rpm, some time 8000, some time 8200......anyway the car is waiting for me to reset it when i have time :)

my car has never failed to hit 8200 unless i was bouncing off the rev limiter before taking off.. i.e taking burnouts too far at the drags.

Hey last week i noticed my rolla revs to 8200rpm in neutral and it has the stock ecu with CAI as the only mod, what do reckon is wrong there.

i had this problem early doors when i first got my car. took it back to toota and they managed to fix it. however not long after that i had my car dyno'd at a melb meet dyno day. anyway i had the slowest sportivo on the day and didnt break the 98kw output when nearly all where over. anyway i cracked it and took it to toyota and explained that it wasnt putting out what it should be even though it had previously had the recall done. toyota tried to tell my that the car wasnt meant to be pushed to its limits and rev"d out. once i told them it wasnt from the way i drove it and that it was professionally dyno'd with a heap of other sportivos and when i told em what kw mine was putting out and what the average for most of the stivos on the day were putting out. they agreed to look at it properly and see what the issue was.

anyway they came to the conclusion that the ecu was faulty(they think?) and they replaced it free of charge.

i dont think they knew what was wrong at all and just replaced the ecu to see what would happen.

since it was replaced the car seems more responsive revs out properly and seems to have more power than it did prior.

however i havnt had it dyno'd since to make sure.

what im getting at is keep putting pressure on toyota and explain about others who have had these problems and what was done to fix em. sooner or later they will buckle and fix it properly.

toyota are just slack........

this is what iam worry about, so u had the ecu recall done, and its still not making the power it should? could it be that the first ecu recall u had was fake and they didnt actually put the new ecu in and try to save money, because just seems strange that they put new ecu in mine and still have the old ecu's data on it....the first day i got my car back i did feel there was more power, but now its not much different to b4

      Turboed Corolla Overbuilt?

      that engine will be fine, the rods are the main thing to be concerned about. The 2860 is a decent turbo for the 1zz but in this day and age I'd go for a G25-550. The injectors might be on the small side, we run DW1000's. You need a full length injector, the shorter injectors with adaptors like ID1050x dont fit the 1zz head. You don't need an aftermarket intake manifold, if you do go down that path, avoid the CNC innovations unit, it's garbage. Do the boost control with a MAC valve and control it with the aftermarket ECU of your choice, I use Link stuff on most of my builds with the G4x Storm as the minimum. I also wire a fuel pressure sensor and oil pressure sensor to the ECU in my installs. Use a decent intercooler, the better cores (ARE, PWR, Garrett, Vibrant, Plazmaman, Hypertune) work a lot better than the chinese stuff like Aeroflow. a 450x250-300 fits fairly well with custom end tanks to route the cooler pipes through next to the radiator Don't forget about the clutch and gearbox. These days I like the Uniclutch twinplate, Above 300whp you'll want to think about upgrading the 3rd and 4th gears in the box also with the SSC (Hollinger) gear set and install an LSD of your choice. If you're going to give it a hard time, you'll also want an oil cooler. I like the HKS thermostat type sandwich plates and setrab or mocal oil coolers with -10 speedflow fittings/lines (Chinese AN fittings neck down to a lot smaller internal diameter in their bends, not great for flow) You'll also want to think about brakes, Celica or Sportivo front calipers will bolt on with sportivo discs as a starting point. To have somewhere like Tunehouse do the work you'll want to budget somewhere between 20-40K

      Camry Touring 2010 Fuel consumption 15.2L/100km. Normal?

      I did the mathematics myself regarding costs vs benefits for fuel injector cleaner. I have changed from 91ULP to 95PULP and 98PULP. Price difference can be about 13 -20 cents. Compared to 91ULP, Premium quality fuel should have a better quality additive package designed to have superior engine cleaning capabilities so the engine can perform at their best.

      Disconnecting winch, lightbar and UHF

      Generally, yes. In the 60s, and earlier, there were cars with positive grounds, so I'm always a bit hesitant to say the negative wire. It is always the one that bolts to the body. Herb

      2011 Land Cruiser 1VD-FTV Engine Won't Start After Overhaul

      Hi everyone, I have a 2011 Land Cruiser VDJ200 with a 1VD-FTV engine. I recently had the engine fully overhauled due to a blown head gasket. However, after the overhaul, the engine is not starting. It only cranks but doesn't fire. I've checked the following DTC codes: Internal memory EEPROM error Low rail pressure The actual rail pressure data shows: 240 bar during cranking 61 bar when ignition is off Based on these findings, I suspect the following potential causes: =Defective Diesel High-Pressure Pump =Leaking Piezoelectric Injectors =Diesel Fuel Bypassing to the DPF Circuit =Faulty Injector Drivers I'm hoping for some expert advice to help diagnose and resolve this problem I'm seeking expert advice on how to troubleshoot and resolve this issue. Any suggestions or guidance would be greatly appreciated.
