whilst they are interchangle and the car will start etc

some MEC chip types are not, you may find if you get the wrong MEC chip type, the car runs OK and idles etc but as soon as you drive it, it becomes mega sluggish and performs like ASS

i had this on my series 2 GTST with a remapped ECU, the remap was done to suit basic mods and i connected it up, took it for a spin and it ran like a bucket of crap

turns out the MEC chip type was wrong and i had to use a different MEC chip number. ask a remapper what the MEC chip type means, from memory the guy in sydney taso i think knows what it means

Your mines ecu will probably have the speed limiter removed (all JDM cars are limited to 180km/hr) and be tuned differently from stock.

Are you planning to get a Nistune?

If the answer is yes then it may be possible to take out the Mines chip from your ecu and replace it with the Nistune chip (or it may be glued in too securely).

If the answer is no then ideally you would put your car on a dyno and do a run with the Mines ecu and then a stock ecu and keep the most suitable one.

Its different from stock, i emailed Mines and asked what they had done to it.

I would like to get a nistune, but i also want to be able to control all the stuff and aftermarket ecu's do that, but i am leaning towards a nistune due to the shear price, and if i give my fiance 2 options she would chose the cheaper option allowing me to get it sooner.

If i get a nistune and cant take the chip out of my mines i am screwwed, so i guess ill have a spare one ready to get chipped and put in and tuned

From memory the MEC number Paul is going in about is the type of chip in the ECU. so like he said you may have trouble putting say a MEC123 chip into an ECU board that is designed/programmed to read a MEC987 chip. The reason people swap just chips around is to reflash the tune, you pull the old chip out and install a new one with a tune burnt on it. It makes sense when doing this to keep the chip types the same.

Because your looking at using the whole ecu you should be ok using either the 0V800 or 0V801. I'm certain there wasn't any changes in sensor types or wiring between the 98-99 run of ecu's (800) and the 99-on (801). also, either ecu is able to be nistuned.

I know it's a different car but still a RB Nissan, I ran a 89 ecu in my 92 R32 without an issue.

Edit: should also add that the 89 ecu had a different MEC number to the original 92 ecu and I had no issues.

Buy the nistune chipped ecu from KJB-R33. It will almost certainly work and if by some chance it doesn't you could always on sell it - its only the price of the Nistune chip anyway you could always take that out and it would be worth the price.

      Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?

      Duncan's V37.......race car?

      By PranK · Posted

      This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!

      OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.

      OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers) Replacement of the Valve body (if you removed it) is the "reverse of assembly". Thread the electrical socket back up through the trans case, hold the valve body up and put in the bolts you removed, with the correct lengths in the correct locations Torque for the bolts in 8Nm only so I hope you have that torque wrench handy (it feels really loose). Plug the output speed sensor back in and clip the wiring into the 2 clips, replace the spring clip on the TCM socket and plug it back into the car loom. For the pan, the workshop manual states the following order: Again, the torque is 8Nm only.
