CHECHEN

i`have 3 ecu`s from r30 skyline. 300zx very hard to find in russia.

i`m found wat is a chips. HN48364P is 2764 8k memory. hn25089 - 2708 1k memory

Can you give a scheme? how ballast resistor work? i`m have a burnout power transistor on my l20et.

i`m dont understand fully your question. Can you shot a picture of your dizzy? Your ignition system is vacuum advance or it`s uses a hall effect sensor? if in your dizzy not used contackt breaker, then it using a hall effect sensor with power transistor.

Thank You. I`m use a search and found advice to change L20ET for RB25DE injectors. I`m buy a fuel ramp from RB25DE not a look for it. But i have a some trouble. RB25DE injectirs is side load, my L20ET is up load. Thank you once again

I`m dont need that... Procedure is 99% similar with this http://wiki.r31skylineclub.com/index.php?title=ECU_Chipping But on r31 using easy to read 27c128 memory chip. in r30 ecu 2 rom chips with switch on A15 adress line. it`s hard to read. But i`m will solder a adapter for 27c128 adaptation for this ecu.

i`m dont saw it. i`m can`t read hitachi memory chips with my programmator. it`s all. If you can, make it and give me bin-file. I`m rebuild my ecu for 27c512 or 27c256.

Ok, i`m open a ECU an what i see: hd6802 processor (Hitachi MC6802 analog datashet i have) 24 pin ram chip near processor (HM46810P Hitachi Semiconductor :: General-Purpose Static RAM 128*8 bits datasheet i have) 24 PIN Mask rom (HN48364P i`cant found datasheet. but i think it`s 8192 bytes size no datasheet) 24 PIN EPROM (hn25089 i`m think it`s 1024 bytes no datasheet). My chinese programmer UP48 dont support these chips. Chinise guys says: But i don`t have datasheets How I can read all memory? Maybe solder a adapter like 27c512 take a adress and datalines from processor and read this like 27c512?

Paul Newman Ads in Daitona more better, i think

I`m wanna l28et block!!!! How much cost shipping to Russian Federation?

i found a ecu wiring on r31 wiki it`s 99% similar Link http://wiki.r31skylineclub.com/index.php?t...gory:Electrical

Did you kill a ants in your scanner???

wiring diagrams for L20ET HR30 NEEDED!!!

i`m buy a second SKYLINE HR-30 First buyed SKYLINE: Now i`m want repair a coupe and sedan use as parts donor

Hi! I`m want boost up my l20et. I`m buy a watercooled tourbine from VG30DET 15 PSI, and fuel rail with injectors from rb25DE it`s a 270cc? What i can make with MAF sensor for good work with this setup? May be make spring in maf harder?
